Lake Committee Scope: This Committee shall have primary responsibility for documents on the fire safety criteria for recreational vehicles and recreational vehicle parks. This list represents the membership at the time the Committee was balloted on the text of this edition. Since that time, changes in the membership may have occurred. A key to classifications is found at the front of this book. The Technical Committee on Recreational Vehicles is presenting two Reports for adoption, as follows: Report I: The Technical Committee proposes for adoption, amendments to NFPA 1192, Standard on Recreational Vehicles, 2002 edition. NFPA is published in Volume 10 of the 2003 National Fire Codes and in separate pamphlet form. NFPA 1192 has been submitted to letter ballot of the Technical Committee on Recreational Vehicles, which consists of 24 voting members. The results of the balloting, after circulation of any negative votes, can be found in the report. Report II: The Technical Committee proposes for adoption, amendments to NFPA 1194, Standard for Recreational Vehicle Parks and Campgrounds, 2002 edition. NFPA is published in Volume 10 of the 2003 National Fire Codes and in separate pamphlet form. NFPA 1194 has been submitted to letter ballot of the Technical Committee on Recreational Vehicles, which consists of 24 voting members. The results of the balloting, after circulation of any negative votes, can be found in the report

2 NFPA 1192 BLOOM: Vapor Resistant is subjective and does not insure dangerous or flammable vapors or gases cannot enter a recreational vehicle. A Vaportight compartment insures safety of the component and occupants, and is readily understood Log #CP14 Final Action: Accept ( Entire Document ) Log #44 Final Action: Accept ( Entire Document ) Recommendation: Where ever the terms LP-Gas, gas, fuel*, or liquefied petroleum gas appear (including Annex A & B), replace with the term propane. (*fuel as it is referring to LP-Gas/propane not gasoline) Substantiation: The term propane is the most commonly used language by consumers, RV technicians, dealers and the RV Industry at large. The majority of documentation on this topic refers to prpane. In addition the National LP-Gas Association recently changed its name to the National Propane Association. Also, an individual 2005 code change proposal has been submitted to deal with the needed change involving the definition of Liquefied Petroleum Gas (LP-Gas and LPG) Log #5 Final Action: Reject ( Entire Document ) Submitter: Gerald Spivey Streator, IL Recommendation: Now available is a safety ladder that would help people exit from the window to the ground, which is approximately 8 ft high. I think this ladder should be mandatory for all 5th wheel trailers with windows over 7 ft high. Substantiation: Camping trailers are required to be built to specifications of the RVIA, which includes escape windows, fire extinguishers, smoke detectors, and all other codes. Note: Supporting material is available for review at NFPA Headquarters. Committee Statement: The proponent did not make a specific proposal Log #CP3 Final Action: Accept ( Entire Document ) Submitter: Technical Committee on Recreational Vehicles Recommendation: Change the following terms as they appear in the standard: 1. Change liquid level gauge; vent valve; outage gauge; outage valve to fixed maximum liquid level gauge 2. Change filler valve; fill valve; double backflow check valve; double backflow check filler valve to double check filler valve 3. Change check valve; back check valve to backflow check valve 4. Change excess flow check valve to excess flow valve 5. Change relief valve; relief device to pressure relief valve 6. Change pressure relief to pressure relief device Substantiation: This is an editorial revision to correlate the various terms into one consistent and more accurate term Log #CP5 Final Action: Accept ( Entire Document ) Submitter: Technical Committee on Recreational Vehicles Recommendation: Change vaportight to vapor resistant where it appears in the standard. Add a new definition to Chapter 3 as follows: Vapor Resistant: Constructed so that gas or air is inhibited from entering or leaving except through vents or piping provided for the purpose. Annex Note - Examples of vapor resistant include construction where penetrations, seams or joints are caulked, sealed, filled or equivalent. Substantiation: Vaportight was not defined and unenforceable. Vapor Resistant continues to ensure a level of safety that is necessary without being subjective. Ballot Results: Affirmative: 18 Negative: 1 Submitter: Technical Committee on Recreational Vehicles Recommendation: Complete the editorial revisions to the NFPA Manual of Style for the entire document. Substantiation: In the last cycle NFPA 1192 was only partially revised to meet the NFPA Manual of Style. The chapters of the standard were reorganized and numbering was revised however the paragraphs were not broken out into individual requirements. A task group of the committee has been formed to review staff revisions and complete the editorial revisions of the standard to the Manual of Style Log #CP7 Final Action: Accept ( 1.2 ) Submitter: Technical Committee on Recreational Vehicles Recommendation: The purpose of this standard shall be to provide the minimum criteria for recreational vehicles that are considered necessary to provide a reasonable level of protection from loss of life from fire and explosion. Substantiation: Under the NFPA Manual of Style, Table identifies that the term Reasonable is unforceable and vague Log #CP8 Final Action: Accept ( ) Submitter: Technical Committee on Recreational Vehicles Recommendation: Revise as follows: This standard is applicable shall apply to new recreational vehicles manufactured on or after September 1, 2002, however, nothing shall prevent the use of the standard prior to September 1, 2002, if the purchaser and the manufacturer agree. Substantiation: Editorial changes based on the NFPA Manual of Style, plus changing the effective date from 2002 to 2005 in order to have an accurate date upon publication. The last part of the sentence is unnecessary, since AHD would determine earlier use Log #127 Final Action: Reject ( (b) (1) ) Submitter: Joseph M. Bloom, Bloom Fire Investigation Recommendation: This section at present reads The pressure relief valve discharge shall be directed upward or downward within 45 degrees of vertical horizontal, so that its discharge shall not directly impinge on the prime mover engine nor be directed into the interior of the vehicle. The section should replace the word vertical with the word horizontal for motor home applications, reflecting the original case as stated in all previous editions of NFPA 501C. This should be an exception to the section. Substantiation: 1. When a relief valve is placed at or near vertical, facing the ground, as this section allows, a release of highly pressurized propane will cause a mushroom effect against the ground, causing the expelled contents to impinge into the underside and interior of the vehicle. The relief valve cannot face up, as burning contents under pressure will burn into the floor. In a fire scenario, this may effectively block and prevent egress as the entire underside of the motor home may be instantly engulfed in fire. 2. Once ignited, the mushroom effect will raise the temperature and pressure of the tank and relief valve and may overcome its designed limits, resulting in either a vapor explosion and/or boiling liquid expanding vapor explosion, placing nearby persons and property at substantial risk of damage and injury

3 3. The relief valve placed at the bottom of a tank, as is now allowed, will leave the relief valve under the liquid portion, so that any release of pressure will force liquid, not vapor, to expel. As the liquid expands into vapor at an expansion rate of 270:1, a vapor cloud may be generated, allowing for the very real potential of a significant propane explosion, placing life and surrounding property at great risk. Committee Statement: Standard date references are routinely updated by NFPA staff during the revision cycle. With the relief valve in the vertical position, there is the potential for a massive LP-gas explosion in the event of a motor home fire in a densely populated area. Although the relief valve placement horizontally is less than ideal due to a horizontal flame torch propagation of 30 ft or more during relief, the potential Log #21 ( ) Final Action: Accept in Principle of explosion is minimized. Submitter: Bob Eugene, Underwriters Laboratories Inc. Committee Statement: The section reference is based on an earlier edition of NFPA 1192 not the 2002 edition. The committee believes having the relief valve at horizontal could endanger life or property. Based on current design, the relief valve communicates only with the vapor space. Ballot Results: Affirmative: 17 Negative: 1 Abstain: 1 Recommendation: Revise text to read as follows: UL 842, Standard for Valves for Flammable Liquids, Substantiation: Revised date notes the most recently ANSI approved edition. in Principle Updates will be reviewed by committee and staff. Committee Statement: Standard date references are routinely updated by NFPA staff during the revision cycle. BLOOM: Until the 1999 edition of, all LP-gas systems had relief valves mounted in a horizontal orientation, for safety reasons. The reference to the relief valve orientation change from the horizontal to the vertical was not addressed nor discussed nor voted on by the committee according to records Log #22 ( ) Final Action: Accept in Principle This is a serious matter, where the committee consensus now believes the relief valve at horizontal could endanger life or property. However, a vertical orientation may be far more dangerous. Does the committee need to advise NHTSA and all manufacturers of the fire and life safety problems as there are hundreds of thousands of RVʼs in operation at this time with horizontally mounted relief valves. Explanatin of Abstention: PABIAN: Voted to abstain to review proposal in more depth. Submitter: Bob Eugene, Underwriters Laboratories Inc Log #18 Final Action: Accept in Principle ( ) Submitter: Bob Eugene, Underwriters Laboratories Inc. Recommendation: Revise text to read as follows: UL 144, Standard for LP-Gas Regulators, Substantiation: Revised date notes the most recently ANSI approved edition. in Principle Updates will be reviewed by committee and staff. Committee Statement: Standard date references are routinely updated by NFPA staff during the revision cycle. Ballot Results: Affirmative: 18 Abstain: 1 Explanatin of Abstention: BLOOM: Not received Log #19 Final Action: Accept in Principle ( ) Submitter: Bob Eugene, Underwriters Laboratories Inc. Recommendation: Revise text to read as follows: UL 484, Standard for Room Air Conditioners, Substantiation: Revised date notes the most recently ANSI approved edition. in Principle Updates will be reviewed by committee and staff. Committee Statement: Standard date references are routinely updated by NFPA staff during the revision cycle Log #20 Final Action: Accept in Principle ( ) Submitter: Bob Eugene, Underwriters Laboratories Inc. Recommendation: Revise text to read as follows: UL 569, Standard for Pigtails and Flexible Hose Connectors for LP-Gas, Substantiation: Revised date notes the most recently ANSI approved edition. in Principle Updates will be reviewed by committee and staff Recommendation: Revise text to read as follows: UL 1484, Standard for Residential Gas Detectors, Substantiation: Update to current standard. in Principle Updates will be reviewed by committee and staff. Committee Statement: Standard date references are routinely updated by NFPA staff during the revision cycle Log #23 Final Action: Accept in Principle ( ) Recommendation: Add text to read as follows: UL Publications UL 125, Valves for Anhydrous Ammonia and LP-Gas (Other than Safety Relief), Substantiation: Editorial. A 2005 code change proposal has been submitted under (1) to reference this UL standard. in Principle Updates will be reviewed by committee and staff. Committee Statement: Standard date references are routinely updated by NFPA staff during the revision cycle Log #24 Final Action: Accept in Principle ( ) Recommendation: Add text to read as follows: UL Publications UL 2061, Adapters and Cylinder Connection Devices for Portable LP-Gas Cylinder Assemblies, Substantiation: Editorial. A 2005 code change proposal has been submitted under (2) to reference this UL standard. in Principle Updates will be reviewed by committee and staff. Committee Statement: Standard date references are routinely updated by NFPA staff during the revision cycle.

4 Log #CP1 Final Action: Accept ( Chapter 3 Definitions (GOT) ) Submitter: Technical Committee on Recreational Vehicles Recommendation: Adopt the following definitions from the NFPA Glossary of Terms for the following items: Cylinder. (secondary) NFPA 1192, 2002 ed. A portable container constructed in accordance with U.S. Department of Transportation Specifications for LP-Gas Containers (49 CFR). External Pressure Relief Valve. (preferred) NFPA 58, 2001 ed. A pressure relief valve that is used on older domestic containers, on pressure relief valve manifolds, and for piping protection where all the working parts are located entirely outside the container or piping. Flush-Type Full Internal Pressure Relief Valve. (preferred) NFPA 58, 2001 ed. An internal pressure relief valve in which the wrenching section is also within the container connection, not including a small portion due to pipe thread tolerances on makeup. Full Internal Pressure Relief Valve. (preferred) NFPA 58, 2001 ed. An internal pressure relief valve in which the wrenching section is also within the container connection, not including a small portion due to pipe thread tolerances on makeup. Identified (as applied to equipment). (preferred) NFPA 79, 2002 ed. Recognizable as suitable for the specific purpose, function, use, environment, application, and so forth, where described in a particular code or standard requirement. Substantiation: Adoption of definitions will assist the user by providing consistent meaning of defined terms throughout the National Fire Codes. Ballot Results: Affirmative: 18 Negative: 1 HOPKINS: Log CP1 should have been written to indicate that the definitions of external pressure relief valve, flush-type full internal pressure relief valve and full internal pressure relief valve be moved to the annex. This would then match the action taken by the Committee on these definitions in Log #33. Comment on Affirmative: MCTIER: The definition of Full Internal Pressure Relief Valve is the same as the definition of the Flush Type Full Internal Pressure Relief Valve and is a mistake. The definition of Full Internal Pressure Relief Valve is as follows: Full Internal Pressure Relief Valve: A pressure relief valve for engine fuel and mobile container use in which all working parts are recessed within the container connection and the spring and guiding mechanism are not exposed to the atmosphere Log #25 Final Action: Accept in Principle ( Compartment ) Recommendation: Delete the existing definition and replace it with the following: Compartment. A completely enclosed volume designed to provide for a separate area. Substantiation: NFPA requested these preferred definitions be accepted so as to be consistent throughout the National Fire Codes. However, the meaning, when applied to RV applications does not work as well as the original 1999 (secondary) definition. in Principle Revise definition as follows: An enclosed volumetric space designed to provide for a separate area. Committee Statement: The committee agrees with the submitter and further feels that this revision more accurately describes the term Log #26 Final Action: Accept ( Container ) Recommendation: Delete the existing definition and replace it with the following: Container: A tank or cylinder. Substantiation: NFPA requested these preferred definitions be accepted so as to be consistent throughout the National Fire Codes. However, the meaning, when applied to RV applications does not work as well as the original 1999 (secondary) definition Log #27 Final Action: Accept in Principle ( Interior Finish ) Recommendation: Delete the existing definition and replace it with the following: Interior Finish. The exposed interior surface in combination with the substrate to which it is applied. Interior finish shall include any material (e.g., paint, wallpaper, decorative panels) that is affixed to such surfaces. Substantiation: NFPA requested these preferred definitions be accepted so as to be consistent throughout the National Fire Codes. However, the meaning, when applied to RV applications does not work as well as the original 1999 (secondary) definition. in Principle Move second sentence to Annex for the definition: Interior Finish. The exposed interior surface in combination with the substrate to which it is applied. A Interior finish includes any material (e.g., paint, wallpaper, decorative panels) that is affixed to such surfaces. Committee Statement: The second sentence should not be part of the definition. It is explanatory information and therefore should be in the Annex Log #28 Final Action: Accept ( Propane ) Recommendation: Change the title to read: Propane (Liquefied Petroleum Gas, LP-Gas, LPG). Substantiation: The term propane is the most commonly used language by consumers, RV manufacturers, dealers and RV technicians. The majority of documentation on this topic refers to the term propane. For example the National LP-Gas Association recently changed its name to the National Propane Association Log #30 Final Action: Accept ( ) Recommendation: Revise the reference at the end of the sentence from (see ) to read (see ). Substantiation: Editorial. The current reference is wrong. The motorhome definition needs to be referred to the RV definition not to the recreational park trailer definition Log #29 Final Action: Accept ( Motor Home ) Recommendation: Delete the term permanently from the sentence Motor Home. A vehicular unit designed to provide temporary living quarters for recreational, camping, or travel use, built on or permanently attached to a self-propelled motor vehicle chassis or on a chassis cab or van that is an integral part of the completed vehicle. Substantiation: There exists no definition for the term permanent and therefore this requirement is unenforceable and vague

5 Log #31 Final Action: Reject ( Pipe ) Recommendation: Delete the existing definition and replace it with the following: Pipe. Rigid materials (e.g., iron pipe) of the gas system. Substantiation: NFPA requested these preferred definitions be accepted so as to be consistent throughout the National Fire Codes. However, the meaning, when applied to RV applications does not work as well as the original 1999 (secondary) definition. Committee Statement: The current definition works with the inclusion of plumbing requirements in this edition of the standard Log #32 Final Action: Accept in Principle ( Piping ) Recommendation: Delete the existing definition and replace it with the following: Piping. The materials of the gas supply system that convey gas from source to appliance, including both rigid (e.g., iron pipe) and semi-rigid (e.g., copper) materials of the gas supply system. Substantiation: NFPA requested these preferred definitions be accepted so as to be consistent throughout the National Fire Codes. However, the meaning, when applied to RV applications does not work as well as the original 1999 (secondary) definition. in Principle Revise definition as follows: Piping. The tubing or rigid conduit of the system. Delete through Committee Statement: The change in language is more inclusive eliminating the need for the sub-definitions and more clearly states the definition of piping Log #33 Final Action: Accept in Principle ( Pressure Relief Valve ) Recommendation: Delete the existing definition and replace it with the following: Pressure Relief Valve. A type of pressure relief device designed to both open and close to maintain internal fluid pressure. Substantiation: NFPA requested these preferred definitions be accepted so as to be consistent throughout the National Fire Codes. However, the meaning, when applied to RV applications does not work as well as the original 1999 (secondary) definition. in Principle Revise the definition to read: Pressure Relief Valve. A type of pressure relief device designed to both open and close to maintain internal fluid pressure. Move all subdefinitions ( through ) to Annex material for the definition. Committee Statement: The committee agrees with the submitter and by moving the subdefinitions to the Annex retains the information in proper form recognizing that the terms are not used in the rest of the standard Log #34 Final Action: Reject ( External Pressure Relief Valve ) Recommendation: Delete definition External Pressure Relief Valve. A relief valve tht is located entirely outside the container connection excerpt the threaded portion, which is screwed into the container connection, and that has all of its parts exposed to the atmosphere. Substantiation: This definition was added during the 2002 MOS process and is not necessary because it is not used within the body of the text. Committee Statement: See Committee Action on ( Log #33) Log #35 Final Action: Reject ( Internal Spring-Type Pressure Relief Valve ) Recommendation: Delete definition Internal Spring-Type Pressure Relief Valve. A relief valve in which only the spring and stem are within the container connection, and the spring and stem are not exposed to the atmosphere. Substantiation: This definition was added during the 2002 MOS process and is not necessary because it is not used within the body of the text. Committee Statement: See Committee Action on (Log #33) Log #36 Final Action: Accept ( Tank ) Recommendation: Delete the existing definition and replace it with the following: Tank. A container constructed in accordance with the Section VIII, Rules for the Construction of Unfired Pressure Vessels of the Boiler and Pressure Vessel Code. Substantiation: NFPA requested these preferred definitions be accepted so as to be consistent throughout the National Fire Codes. However, the meaning, when applied to RV applications does not work as well as the original 1999 (secondary) definition Log #CP9 Final Action: Accept ( ) Submitter: Technical Committee on Recreational Vehicles Recommendation: Revise definition as follows: Camping Trailer. A vehicular portable unit that is mounted on wheels and constructed with collapsible partial side walls that fold for towing by another vehicle and unfold at the campsite to provide temporary living quarters for recreational, camping, or travel use. Substantiation: All other RV definitions (motorhomes, T.T., 5th wheel) All RVʼs are portable therefore it is an unnecessary term Log #37 Final Action: Reject ( Tubing ) Recommendation: Delete the existing definition and replace it with the following: Tubing. Semi-rigid (e.g., copper tubing) materials of the gas system. Substantiation: NFPA requested these preferred definitions be accepted so as to be consistent throughout the National Fire Codes. However, the meaning, when applied to RV applications does not work as well as the original 1999 (secondary) definition. Committee Statement: The existing definition is adequate

6 Log #CP2 Final Action: Accept ( 3.4 ) Submitter: Technical Committee on Recreational Vehicles Recommendation: Combine the definitions of 3.3 and 3.4 into Section 3.3. Substantiation: The combination of the definitions is more appropriate now that a plumbing chapter has been added to NFPA Log #38 Final Action: Accept ( Continuous Waste ) Recommendation: Add the following definition as new Continuous Waste. A drain connecting the compartments of a set of fixtures to a trap or connecting other permitted fixtures to a common trap. Substantiation: This definition existed in the 1999 edition of ANSI A119.2 but was inadvertently omitted in the publication of the 2002 edition Log #39 Final Action: Accept ( Vent System ) Recommendation: Relocate existing Vent System (waste) definition to be a new subcategory of vent. Substantiation: This definition was moved during the 2002 MOS process, and should be located under vent section Log #40 Final Action: Accept ( Water Distribution System ) Recommendation: Delete the term permanently from the sentence Water Distribution System. The potable water piping within or permanently attached to the recreational vehicle. Substantiation: There exists no definition for the term permanent and therefore this requirement is unenforceable and vague Log #41 Final Action: Accept ( Toilet - Trap Arm ) Recommendation: Rephrase the title to read: Toilet - Trap Arm. Substantiation: This title was changed during the 2002 MOS process, and should be rephrased, since there is no such components as a toilet trap arm Log #CP10 Final Action: Accept ( ) Submitter: Technical Committee on Recreational Vehicles Recommendation: Delete the word adequate from the paragraph. Substantiation: Under the NFPA manual of style, Table identifies that the term adequate is unenforceable and vague Log #42 Final Action: Reject ( 4.4 ) Recommendation: Revise 4.4 to read as follows: 4.4 Electrical Requirements. All 120V electrical installations, systems, and equipments shall comply with Article 551, Parts I and III through VI, of NFPA 70, National Electrical Code. All low voltage electrical installations, systems, and equipment shall comply with ANSI/RVIA 12V, Low Voltage Systems in Conversion and Recreational Vehicles Insert NEC Article 551: Sections I, III, IV, V, VI plus all applicable 120V definitions from Section into ANSI A119.2 as new paragraph Substantiation: This would allow the NFPA 1192/ANSI A119.2 Standard to contain all 120V RV requirements, without referring to the NEC Article 551. Committee Statement:While extracting the information may be beneficial for the end user. There are too many requirements that may be omited from other parts of the NEC that may cause confusion Log #43 Final Action: Reject ( (New) ) Recommendation: Insert 551 sections I, III, IV, V, VI plus applicable RV definitions from section II directly ANSI A Substantiation: Per the NFPA MOS, this is an acceptable procedure and would allow the NFPA 1192/ANSI A119.2 to incorporate all the 120V requirements, without referring to the NEC. Committee Statement:While extracting the information may be beneficial for the end user. There are too many requirements that may be omited from other parts of the NEC that may cause confusion Log #124 Final Action: Reject ( Chapter 5 ) Submitter: Joseph M. Bloom, Bloom Fire Investigation Recommendation: Dispensing, transfer, or any other method of supplying or providing gasoline or other motor fuels for vehicle use shall not be permitted. This does not apply to the tank providing fuel for a motor home engine. Substantiation:An option in some fifth wheel trailers is a gas tank with dispensing pump and hose, and a direct nearby open door to the interior. Committee Statement: The submitter is encouraged to identify a specific paragraph for revision. Ballot Results: Affirmative: 18 Negative: 1 BLOOM: This is not revision material, and the committee may find it appropriate to add a section to the document. Dispensing of flammable liquids by untrained persons, minors without adequate supervision, or an accident cannot be prevented. Firefighters may not be aware that a fuel-dispensing tank is located under a trailer and are subject to severe burn injuries or death in the event of a rupture while aggressively extinguishing a fire Log #125 Final Action: Reject ( Chapter 5 ) Submitter: Joseph M. Bloom, Bloom Fire Investigation Recommendation: Gasoline or motor fuel tanks not intended specifically for a generator shall not be permitted in trailer applications. Substantiation: An option in some trailers is a gas tank with dispensing pump which transfers gasoline to ATVʼs, motorcycles, etc

7 Committee Statement: The submitter is encouraged to identify a specific paragraph for revision. Comment on Affirmative: HOPKINS: Existing parts (2)(c)&(d) were inadvertently omitted and should have been included in this proposal, with necessary Manual of Style changes also made to these sections. Ballot Results: Affirmative: 18 Negative: 1 BLOOM: See my Explanation of Negative on (Log #124) Log #47 ( ) Final Action: Accept Log #45 Final Action: Accept ( 5.2.1(1) ) Recommendation: Delete the phrase non permanently mounted from the sentence. One but not more than three nopermanently mounted cylinders having individual water capacities of 105 lb (47.6 kg) maximum [approximately 45 lb (20.4 kg) LP-Gas capacity]. Substantiation: The phrase is unnecessary and is undefined and therefore unenforceable Log #46 Final Action: Accept in Part ( 5.2.1(2) ) Recommendation: Delete the phrase permanently mounted from the sentence. One but not more than three permanently mounted tanks having a maximum aggregate water capacity of 200 gal (757 L) maximum [approximately 672 lb (323 kg) LP-Gas capacity] Substantiation: The phrase is unnecessary and is undefined and therefore unenforceable. in Part Revise paragraph to read: One or more permanently mounted tanks having a maximum aggregate water capacity of 200 gal (0.8m 3 ). maximum [approximately 672 lb (323 kg) LP-Gas capacity] Committee Statement:The committee accepts the deletion of the term permanently mounted however no substantiation has been provided for limiting to three tanks. The deletion of the maximum weight reference because tanks are filled by volume not by weight Log #CP11 Final Action: Accept ( ) Submitter: Technical Committee on Recreational Vehicles Recommendation: Revise as follows: Location of LP-Gas Containers. LP-Gas containers shall be in accordance with through LP-Gas containers that do not meet the provisions of shall not be installed nor shall provisions be made for installing or storing any LP-Gas containers, even temporarily, inside any recreational vehicle New LP-Gas cylinders that have never contained LP-Gas and are supplied as original equipment shall be permitted to be transported inside the vehicle LP-Gas containers with their control valves shall be installed in compliance with one of the following: (a) In a recess or compartment other than on the roof that is vaportight to the inside of the recreational vehicle. (b) Mounted on the tongue or A-frame of a travel or camping trailer or forward of the front bulkhead below the overhang of a fifth wheel trailer and not lower than the bottom of the trailer frame Containers shall not be mounted on the exterior of the rear wall or the rear bumper of the vehicle. Substantiation: Reorganized for clarity. Recommendation: Change title to Heat Shielding of LP Containers and Piping. Add new sentence as follows: Propane gas piping located less than 4 1/2 in. from the exhaust system, transmission, or heat producing component of the primary mover engine shall be shielded by a vehicle frame member or by a noncombustible baffle, with an air space on both sides of the frame member or baffle. Substantiation: Currently there is no requirement to prevent LP piping from being right next to exhaust components. Ballot Results: Affirmative: 18 Negative: 1 BUDICA: Change 4 1/2 inches to 12 inches Reason: Future piping may have materials and/or protective coverings other than copper and iron. If plastic or rubberized product is used will be affected at 4 1/2 inches without shielding. Changing from 4 1/2 inches to 12 inches will ensure no effects to materials. If closer than 12 inches, shielding will be required. Also, this will help compensate for any primary engine movement when torqued and untorqued. Change primary mover engine to heat generating engine or device with fuel burning intake/exhaust Reason: Current wording only designates the main engine, but does not account for an auxiliary generator or devices such as Aqua-hot type hot water heaters. The hot exhaust pipes of these devices would also require shielding. Comment on Affirmative: LIVINGSTON: Required clearance is too arbitrary and not based on sound substantiation/testing. Heat generated from an exhaust pipe or muffler in the system is different from heat generated from a catalytic converter, for example. Positioning an LP-gas pipe within 4 1/2 inches from a catalytic converter may not provide enough cooling from air circulation. There is no substantiation for this measurement. The type of baffle is not spcific enough because temperature value have not been established. This action requires further testing under real-world conditions Log #48 Final Action: Accept ( ) Recommendation: Replace 2nd and 3rd sentence with this sentence: The compartment shall be ventilated with at least two vents, each having an aggregate free area equal to at least 0.5 in 2 for each 7 lb (0.5 cm 2 per 500 g) of the total propane fuel capacity of the maximum number of the largest cylinders the compartment can hold. Substantiation: The current 3rd sentence is confusing since it implies the venting at the top and bottom must be equal. This new language is more understandable Log #1 Final Action: Accept ( ) Submitter: Jerome A. Hoover, Monaco Coach Corporation Recommendation: Revise text to read as follows: The manual control of the tankʼs shutoff valve, the LP-Gas fill connection, and the liquid level outage valve of permanently installed tanks shall be located not more than 18 in. (457 mm) from the vehicleʼs outside wall. The LP Gas fill connection and its liquid level outage valve shall be located in accordance with like requirements for LP Gas pressure relief valves (see ). Exception: Vehicles shall be permitted to be equipped with a remotely controlled normally closed electronic shutoff valve installed within 9 in. (228 mm) of the outlet of the tankʼs shutoff valve using piping and tubing. A double backflow check valve shall be installed in the fill opening of the tank. The

8 remote fill connection, liquid level outage valve, and electronic shutoff valve control shall be located within 18 in. (457 mm) of the vehicle outside wall. and shall be located in accordance with like requirements for LP-Gas pressure relief Log #CP13 ( , ) Final Action: Accept valves (see ). Substantiation: Filling the LPG tank is an attended process and is accomplished Submitter: Technical Committee on Recreational Vehicles through a positive mechanical connection with minimal discharge of vapor from the liquid level outage valve when the volume of LPG in the tank reaches 80 percent, and minimal discharge of vapor when the refueling hose is disconnected from the fill connection. The volume is much smaller than the volume of unintended, and unpredictable discharge of LPG due to expansion from the pressure relief valve cited in The standard ( ) also requires instructions that are posted at the LPG and engine fuel fill locations, stating to turn off all pilot lights, appliances, and their igniters before refueling. Because; 1) Tank filling is attended and pressure relief is unattended, 2) Tank filling results in minimal, anticipated discharge and pressure relief results in considerable, unexpected discharge, and 3) Tank filling requires ignition sources be extinguished while pressure relief most often occurs with ignition sources present, then the 3 ft. minimum distance requirements for pressure relief valves is not necessary for LPG fill connections, or liquid level outage valves. Recommendation: Revise current as follows: Location of Tank Appurtenances. The manual control of the tankʼs shutoff valve, the LP-Gas fill connection, and the liquid level outage valve of permanently installed tanks shall be located not more than 18 in. (457 mm) from the vehicleʼs outside wall. The LP-Gas fill connection and its liquid level outage valve shall be located in accordance with like requirements for LP-Gas pressure relief valves (see ). Exception: Location of Remote Controlled Appurtenances Vehicles shall be permitted to be equipped with a remotely controlled normally closed electronic shutoff valve installed within 9 in. (228 mm) of the outlet of the tankʼs shutoff valve using piping or tubing A double backflow check valve shall be installed in the fill opening of the tank The remote fill connection, liquid level outage valve, and electronic shutoff valve control shall be located within 18 in. (457 mm) of the vehicle outside wall and shall be located in accordance with like requirements for LP- Gas pressure relief valves (see ). Renumber the rest of the section accordingly Log #50 Final Action: Accept ( ) Recommendation: In the exception, change the term electronic to electrically operated in two places. Substantiation: Editorial - These shutoff valves have no electronic components Log #49 Final Action: Accept ( ) Recommendation: Delete the phrase permanently installed within the first sentence. The manual control of the tankʼs shutoff valve, the LP-Gas fill connection, and the liquid level outage valve of permanently installed tanks shall be located not more than 18 in. (457 mm) from the vehicleʼs outside wall. Substantiation: The phrase permanently installed is unnecessary and undefined and therefore is unenforceable Log #51 Final Action: Accept in Principle ( Exception ) Recommendation: In the Exception, revise the second sentence to read: A double backflow check valve shall be installed both in the tankʼs fill opening and in the remote fill valve for of the tank. Substantiation: This prevents gas accumulation in the remote fill piping from being released into the atmosphere after filling. in Principle A double backflow check valve shall be installed in the tankʼs fill opening and a single check or double check filler valve in the remote fill connection of the tank. Committee Statement:There is no reason to require a double check valve on the remote fill as one is already required on the tank. Substantiation: Manual of Style revision. Comment on Affirmative: MCTIER: Correct the final version of and as follows: Location of Tank Appurtenances. The manual control of the tankʼs tank shutoff valve, the LP-Gas propane fill connection, and the fixed maximum liquid level outage valve gauge shall be located in accordance with like requirements for LP-Gas pressure relief valves (see ) so that the discharge from these devices shall be not less than 3 ft (0.9 m) measured horizontally along the surface of the vehicle from openings into the recreational vehicle, propane burning appliance intake and exhaust vents, and all internal combustion engine exhaust terminations Location of Remote Controlled Appurtenances Vehicles shall be permitted to be equipped with a remotely controlled normally closed electronic electrically operated shutoff valve installed within 9 in. (228 mm) of the outlet of the tankʼs tank shutoff valve using piping or tubing A double backflow check filler valve shall be installed in the fill opening of the tank The remote fill connection, the fixed maximum liquid level outage valve gauge, and electronic the electrically operated shutoff valve control shall be located within 18 in. (457 mm) of the vehicle outside wall and shall be located in accordance with Substantiation: this revised version covers the previous accepted proposals including the consistent names for equipment Log #52 Final Action: Accept ( ) Recommendation: Revise text to read as follows: Containers shall be equipped with a listed overfilling prevention device. Cylinders with a 4 - lb through 40 - lb propane capacity shall be equipped with a listed overfilling prevention device and a CGA 791 (Type 1, 1-5/16 in. Acme) outlet as described in Compressed Gas Association (CGA) V-1, Compressed Gas Cylinder Valve Outlet and Inlet Connections. Substantiation: All containers on RVs should have overfill prevention devices. The current language would allow a 45 lb cylinder (available) to not have an OPD Log #53 Final Action: Accept ( ) Recommendation: Add new first sentence to as follows: First stage regulators shall have an outlet pressure setting up to 10.0 psi (69 kpa) in accordance with UL 144, Standard for LP-Gas Regulators

9 Substantiation: Separate first stage regulators have a maximum nominal outlet pressure Log #54 Final Action: Accept ( ) Recommendation: Revise the existing first sentence to read: A listed two-stage regulator system or an integral two-stage regulator listed to the requirements of UL 144, Standard for LP-Gas Regulators... Substantiation: Editorial, to clarify the appropriate listing standard Log #55 Final Action: Accept ( ) Recommendation: Revise fifth sentence as follows:...shall have a 1 in. 2 (6.5 cm 2 ) minimum and 2 in. 2 (12.9 cm 2 ) maximum vent opening to the exterior. Substantiation: Limiting the size of this vent will prevent the vent itself becoming large enough to allow water/ice etc. in, compromising the intent of the regulator compartment Log #56 Final Action: Accept ( ) Recommendation: Revise the title of to read: LP-Gas Shutoff Valves, Excess Flow Valves and Back Check Valves. Substantiation: Editorial code change is being submitted under (2) new (d) to address back check valves, so the title of should be changed if accepted Log #57 Final Action: Accept ( (1) ) Recommendation: Delete the phrase permanently mounted in the first sentence. (1) Permanently mounted Tanks shall require a manual shutoff valve equipped with a listed internal excess flow valve that is designed to close automatically at the rated closing flow of vapor or liquid specified by the manufacturer. Substantiation: The phrase is unnecessary, since this requirement would apply to permanent or non-permanent tanks Log #58 Final Action: Accept ( (1) ) Recommendation: Revise (1) to read as follows: (1) Tanks shall require a manual shutoff valve equipped with an internal excess flow valve listed to the requirements of UL 125, Valves for Anhydrous Ammonia and LP-Gas (Other than Safety Relief)... Substantiation: Editorial Log #59 Final Action: Accept in Principle ( (2) ) Recommendation: Revise (2) to read as follows: (2) The mating connection shall be listed to the requirements of UL 2061, Standard for Adapters & Cylinder Connection Devices for Portable LP-Gas Cylinder Assemblies, 1997 and installed with in the regulator furnished and with the vehicle as follows: Substantiation: Editorial, to clarify the appropriate listing standard. in Principle Remove the date reference for the standard. Committee Statement: Editorial. Comment on Affirmative: MCTIER: Delete the phrase with in the regulator furnished and with the vehicle in (2). Substantiation: The mating connection is not necessarily required to be installed only in the regulator PABIAN: The date of the standard be deleted from the code text as the referenced standard in Chapter 2 contains the date. This is consistant with the other referenced standards in Log #60 Final Action: Accept in Principle ( (2)(d) ) Recommendation: Add (d) as follows: (d) The mating connection to the regulator inlet shall be provided with a back check valve. Substantiation: High pressure discharge will occur when the mating connection to the cylinder valve is disconnected for cylinder refilling. Potential exists for the cylinder still attached to a changeover regulator to discharge if the changeover regulator lever is not rotated to the connected cylinder as required for proper operation. There is a nuisance issue with the excess flow valve operation when larger volumes must equalize pressure to open the excess flow valve. in Principle Revise the proposal to read: (d) Each mating connection to the automatic changeover regulator inlets shall be provided with a backflow check valve. Committee Statement: Revised for clarity as to the appropriate location of backflow check valves. The revision also clarifies that automatic changeover regulators need the protection to prevent unintended flow of gas in the event the manual lever is not turned to the appropriate position. Therefore this does not apply to single container two-stage regulation systems Log #3 Final Action: Accept in Principle ( (b) ) Submitter: Joel Creek, Skyline Corporation Recommendation: Revise text to read as follows: (b) The mating connection to the cylinder valve shall also incorporate a listed excess flow valve that will close at a flow not greater than 200 ft 3 /hr at 100 psi (5.66 m 3 /hr at kpa) and has a bypass area that will not allow a flow greater than 10 ft psi (28 28 m 3 /hr at kpa). Substantiation: The conversion from 10 ft 3 /hr to 28 m 3 and 100 psi to 69 kpa are not correct. The conversion is 10 ft 3 /hr equals 28 m 3 /hr and 100 psi equals 689 kpa. Note: Supporting material is available for review at NFPA Headquarters. in Principle Revise the correction as follows: (b) The mating connection to the cylinder valve shall also incorporate a listed excess flow valve that will close at a flow not greater than 200 ft 3 /hr at 100 psi (5.66 m 3 /hr at 689 kpa) and has a bypass area that will not allow a flow greater than 10 ft 3 /hr at 100 psi (0.28 m 3 /hr at 689 kpa).

10 Committee Statement: The committee accepts the change and found that the underlined corrections were also necessary Log #118 ( 5.3 through ) Final Action: Accept Submitter: Matthew Brick, Skyline Corp Log #61 Final Action: Accept ( ) Recommendation: Revise the first paragraph to read: Regulator Pressure Relief Valves A separate first stage of a two-stage regulator system shall incorporate an integral pressure relief valve having a start-to-discharge setting within the limits specified in UL 144, Standard for LP-Gas Regulators The second stage of a two-stage regulator system shall be equipped with one or both of the following: (1)... (2)... Substantiation: Separate first stage regulators require separate pressure relief valves Log #62 Final Action: Reject ( ) Recommendation: Revise as follows: Permanent exterior warning labels with the word WARNING with minimum 1/4 in. (6 mm) high letters and body text with minimum 1/8 in. (3 mm) high letters on a contrasting background shall be affixed to the appliance or appliance compartment and at the fuel source in a visible location indicating the following: Substantiation: Adding this language will standardize this code reference with all other labels that was changed in the 2002 edition by the NFPA Technical Committee Task Group on labels. Committee Statement: The committee could not determine the necessary wording for the label because the appliance manufacturer must determine the specific language to be used Log #63 Final Action: Accept ( ) Recommendation: Delete the existing last sentence, and add a new last sentence as shown. Then move the entire existing to Mounting of LP-Gas Containers. Container openings for vapor withdrawal shall be located in the vapor space when the container is in service or shall be provided with a permanent internal withdrawal tube that communicates with the vapor space in or near the highest point in the container when it is mounted in service position with the vehicle on a level surface. Tanks shall have vapor withdrawal located midway between tank ends. Each cylinder shall be permanently and legibly stamped to show the correct mounting position. Stamping shall be 1/4 in. (6 mm) minimum letter height. The method of mounting in place shall be such as to minimize the possibility of an incorrect positioning of the cylinder. The cylinder shall incorporate a method of mounting that keeps the cylinder in the position it was designed to be used. Substantiation: The existing sentence is unenforceable. The new language is more specific. Moving the requirement to keeps this requirement affiliated with other cylinder requirements. Comment on Affirmative: MCTIER: Revise the new last sentence of to add clarity as follows: The cylinder shall incorporate a method of mounting that keeps the cylinder in the a position it was designed to be used for its designed use. The MOS task force will address the MOS problem of having more than one requirement in a single paragraph Recommendation: Delete Section 5.3 Fuel Oil Supply for Heat Producing Appliances. Delete the entire sections through Substantiation: Are fuel oil requirements applicable for use in recreational vehicles per the definition of recreational vehicles? Fuel oil is for units set on sites with more permanence such as park trailers. Appliances need to be listed for use in recreational vehicles, are fuel oil appliances listed? LP gas is available nationwide and bottled for travel use. The elimination of fuel oil requirements will reduce the size of Chapter 5 by removing information that manufacturers do not use Log #64 Final Action: Accept in Principle ( ) Recommendation: Add anew sentence after exist first sentence of (1) as follows: Wrought iron pipe used on the high pressure side of the regulator shall be Schedule 80. Add new sentence after existing first sentence of (2) as follows: Wrought iron fittings used on the high pressure side of the regulator shall be Schedule 80. Substantiation: Schedule 80 wrought iron pipe is required by NFPA 58, Table (a), 1998 edition when iron pipe is used for high pressure applications. in Principle Revise to read as follows: (1) Schedule 80 steel or wrought iron pipe shall be used where system pressure exceeds 125psig. (2) Schedule 80 steel or wrought iron fittings or forged brass fittings shall be used where system pressure exceeds 125psig. Committee Statement: The committee determined that other materials needed to be identified, and a pressure value needed to be specified Log #65 Final Action: Accept ( ) Recommendation: Revise the third sentence as follows: The system shall be made of materials having a melting point of not less than 1450 F (788 C), except as provided in 5.4.2(6), 5.4.5, 5.4.6, and , or of materials (used in piping or fittings) listed for the specific use intended. Substantiation: The added two references are needed to show other areas of the standard that permit materials to have a melting point less than 1000 degrees Log #66 Final Action: Accept ( ) Recommendation: Delete the words one of and add an s as shown in the second sentence: Conformance shall be permitted to be determined on the basis of test, or the gas piping system shall be permitted to be sized in accordance with one of Tables 5.4.4(a) through Table 5.4.4(d) or other approved method. Substantiation: More than one table is often needed for determining system design and compliance.

11 Log #119 Final Action: Reject ( (a), (b), (c), and (d) ) Submitter: Matthew Brick, Skyline Corp. Recommendation: Tables 5.4.4(a), (b), (c), and (d) sizing of low pressure gas piping and tubing. Revise to include maximum lengths over 40 ft 0 in. up to 50 ft 0 in. After reviewing National Fuel Gas Code, NFPA 54, 1999 Pipe/ Tubing sizing tables (9.26) and (9.28), the BTUH values for LP only systems (piping and semi-rigid tubing) have changed. I assume Tables 5.4.4(a), (b), (c), and (d) were derived from earlier NFPA 54 standards as they coincide with NFPA 54, 1988 Tables (C-16) and (C-17).

It would be helpful to have lengths in these tables up to 50 ft 0 in. as in the CSA Z240 RV Series-99, Z Please inform manufacturers of value changes in LP only systems if changed in Tables 5.4.4(c) and (d). Note: Supporting material is available for review at NFPA Headquarters. Committee Statement: The proposed tables contain columns that appear to be missing information and some sizing errors. Without this information the committee cannot accept the proposal. Comment on Affirmative: MCTIER: Tables (a), (b), (c), and (d) are not clear and are obsolete compared to the new tables now shown in both NFPA 58 and NFPA 54. The tables that should meet the requirements for NFPA 1192 should be extracted from NFPA Edition and they are as follows: 1. Table 12.3 Pipe Sizing Between Second Stage Regulator and Appliance: Nominal Pipe Size 2.

Water Column (based on 1.52 specific gravity gas) In addition we can reference the other (13) Tables shown in Chapter 12 of NFPA 58. The information is the same for propane in both NFPA Edition and NFPA Edition Log #67 Final Action: Accept in Principle ( ) Recommendation: Add an s to the word roof in the first sentence as shown: Tubing shall not be run inside walls, floors, partitions, or roofs, except that 1/4 in. (6 mm) O.D. tubing shall be permitted to be concealed provided it is enclosed with a metallic covering of thickness equivalent to the thickness of the tubing enclosed. Substantiation: Editorial. There are often more than one roof on a RV, especially those with slide-out feature. in Principle Keep the s Change the word roof to ceilings Committee Statement: Better clarifies the intent of the restriction Log #68 Final Action: Accept ( ) Recommendation: Delete end of first sentence as follows:...or roof, except that 1/4 in. (6 mm) O.D. tubing shall be permitted to be concealed provided it is enclosed in a metallic covering of thickness equivalent to the thickness of the tubing enclosed. Substantiation: These materials are not needed or used in modern RV constructions. This language goes all the way back to gas light installations Log #69 Final Action: Reject ( (New) ) Recommendation: Add a new paragraph as follows: Special Requirement for High Pressure Piping. Piping exposed to a working pressure over 30 psi shall be sloped 1/8 in/ft toward the propane container. The high pressure fuel system shall be located entirely on the exterior of the vehicle or in a compartment vaportight to the vehicle interior. Substantiation: See NFPA 58, The recondensation of propane vapor back into liquid can enter the regulator if the piping is not sloped. In a worse case scenario, this could cause complete failure of the regulator. Committee Statement: See Committee Action on (CP #6)

13 Log #CP6 Final Action: Accept ( (New) ) Submitter: Technical Committee on Recreational Vehicles Recommendation: Add a new paragraph as follows: Propane system pressure shall be regulated to 25 psi or less within 24 inches of the container outlet. Substantiation: This language adds additional safety to propane systems by limiting the length of high-pressure piping systems. Comment on Affirmative: MCTIER: Revise new as follows to more specifically define the requirement: Propane system pressure shall be regulated to 25 psi or less at the container outlet within 24 inches of the container outlet if the connecting piping or tubing is over 24 inches in length measured from the container outlet to the integral two-stage regulator or the two-stage automatic changeover regulator system Log #70 Final Action: Accept in Part ( (1) ) Recommendation: Delete the phrase permanently mounted within the sentence and replace with the phrase non-removable. (1) If the regulator is not directly connected to a permanently mounted nonremovable container shutoff valve, it shall be connected to the container shutoff valve by a listed high-pressure flexible hose connector or by material conforming to Substantiation: The phrase non-removable is more easily understood and enforceable. in Part Delete permanently mounted but do not replace with any other language. Committee Statement: The committee agrees with the submitter that the current language should be deleted. However, nonremoveable does not improve the clarity of the requirement Log #71 Final Action: Accept ( (3) ) Recommendation: Delete the term permanently from the sentence. (3) The connection between the shutoff valve of a cylinder intended to be removed and mounted on the tongue (A-frame) and a regulator permanently mounted other than as described in (2) shall be made with a listed highpressure flexible hose connector. Substantiation: The term permanently is unnecessary and is unenforceable Log #72 Final Action: Accept ( (4) ) Recommendation: Change (4) as follows: (4) The connection between the shutoff valve of a cylinder intended to be removed and mounted within a compartment shall be made with a listed high pressure flexible hose connector if the regulator is not directly attached to the shutoff valve. A regulator shall not be permitted to be directly attached to the shutoff valve of a cylinder. Substantiation: A CGA 791 outlet is not designed to withstand the side loading created if a regulator is directly attached to a cylinder. Leakage or failure of the thermal protection could occur Comment on Affirmative: MCTIER: My recommendation is to leave (4) as stated in the 2002 Edition of NFPA We have millions of propane grills that are in service where the propane regulator is equipped with a CGA 791 inlet connection that is directly attached to the shutoff valve of the cylinder. This is the present standard for the industry. Even though an integral two-stage regulator is required for recreational vehicles, the required use of a flexible connector between the inlet of the regulator and the container outlet connection on all single cylinder installations seems like overkill to me. When the regulator is secured in the compartment, particularly with multiple cylinder compartments, the flexible conneector makes good sense Log #73 Final Action: Accept ( (1) ) Recommendation: Change the term container to tank within the sentence. (1) The connection between a permanently mounted regulator or a regulator directly attached to a permanently mounted container tank and the gas supply system shall be made with a listed flexible hose connector or with material conforming to Substantiation: The word tank is the correct term, since this specific requirement is addressing ASME tanks. Ballot Results: Affirmative: 18 Negative: 1 HOPKINS: Committee Action on this proposal should have been accept in principle since Committee Action on Log #74 revised the sentence to eliminate the reference to container altogether Log #74 Final Action: Accept in Principle ( (1) ) Recommendation: Within the sentence in two places change the phrase permanently mounted to non-removable. (1) The connection between a permanently mounted non-removeable regulator or a regulator directly attached to a permanently mounted non-removeable container and the gas supply system shall be made with a listed flexible hose connector or with material conforming to Substantiation: The phrase non-removeable is more easily understood and enforceable. in Principle Revise proposal as follows: (1) The connection between a regulator fixed-in-place and the gas supply system shall be made with a listed flexible hose connector or with material conforming to Committee Statement: Meets the submitters intent and more clearly identifies the requirement Log #75 Final Action: Accept in Principle ( (2) ) Recommendation: Change (2) to read as follows: (2) The connection between a regulator mounted on a cylinder support bracket or a regulator directly attached to the shutoff valve of a cylinder and the gas supply system shall be made with a listed flexible hose connector or with material conforming to A regulator is not permitted to be directly attached to the shutoff valve of a cylinder. Substantiation: A CGA 791 outlet is not designed to withstand the side loading created if a regulator is directly attached to a cylinder. Leakage or failure of the thermal protection would occur. in Principle Revise proposed language as follows: (2) The connection between a regulator not fixed-in-place and the gas supply system shall be made with a listed flexible hose connector. A two-stage regulator is not permitted to be directly attached to the shutoff valve of a cylinder.

14 Committee Statement: Meets the submitters intent and more clearly identifies the requirement. The change recognizes that the dynamic loading on a typical single stage regulator are substantially less and therefore acceptable Log #76 Final Action: Accept ( ) Recommendation: Add a new sentence at the end of as follows: Flexible nonmetallic tubing or hose shall not be permitted to enter the body of a listed range or cooktop as the final connection. Substantiation: Flexible nonmetallic tubing or hose has not been evaluated for use in close proximity to heat sources such as a range burner. In addition, some appliance installation instructions do not address this issue at all Log #14 Final Action: Reject ( ) Submitter: Ronald Mell, R E Mell and Associates Recommendation: Revise the first part of the sentence to read: Quick Disconnect devices with integral shut off used downstream of the LP gas propane regulator... Substantiation: This would add additional safety by requiring the Quick Disconnect device to have a shut off valve integral with the device. In addition this change would match current language found in NFPA 54, paragraph , Exception No. 2, 2002 edition. Committee Statement: See Committee Action on (Log #77) Log #77 Final Action: Accept in Principle ( ) Recommendation: Add the following sentence at the end of : Quick disconnects used on the interior of the vehicle shall also be equipped with a manual shutoff device immediately upstream of the quick disconnect. Substantiation: This language from NFPA 54, should be in A This change would harmonize with CSA Z240 RV Series - 99, (a) Gas Supply Requires Disconnect. in Principle Revise as follows: Quick Disconnect Devices Quick disconnect devices used downstream of the LP-Gas regulator shall be listed for use with LP-Gas and for the specific environment (indoor, outdoor, or both) Quick disconnect devices shall not be capable of connection to the cylinder portion of a cylinder connection device Quick disconnect devices shall either have integral shut-off or shall have a manual shut-off upstream, capable of operation from the same user position as the quick disconnect device. Committee Statement: Additional requirements were necessary to ensure safety. The proposal has been modified to reflect MOS requirements. Ballot Results: Affirmative: 18 Abstain: 1 Explanatin of Abstention: BLOOM: Not received Log #78 Final Action: Accept ( ) Recommendation: Revise text to read: Gas Piping Support. All gas piping shall be supported at intervals of not more than 4 ft (1.2 m), except where adequate support and protection are provided by structural members. All pipe piping shall be rigidly anchored to a structural member within 6 in. (152.4 m) of the supply connection(s) by galvanized, painted, or equivalently protected metal straps, hangers, or fittings. All pipe piping shall be anchored within 6 in. (152.4 mm) of tubing connections at the end of pipe piping runs and within 12 in. (304.8 mm) of tubing connections within pipe piping runs. Substantiation: There is inadequate support for manifolds that are made of copper tubing. Since copper is a softer material than iron, also less rigid, there should be equal or greater support of any diameter and length of copper manifolds used. Ballot Results: Affirmative: 18 Abstain: 1 Explanatin of Abstention: BLOOM: Not received Log #79 Final Action: Accept ( ) Recommendation: Change title to: Testing Low Pressure Piping Systems for Gas Leakage Substantiation: The current and tests are intended only to address the piping system downstream of the LP system regulator. Ballot Results: Affirmative: 18 Abstain: 1 Explanatin of Abstention: BLOOM: Not received Log #4 Final Action: Accept ( (1) ) Submitter: Joel Creek, Skyline Corporation Recommendation: Revise text to read as follows: (1) The entire system shall be pressurized to not less than 8 in. water column (1.99 kpa) or more than 14 in. water column (3.5 kpa), the appliance shutoff valves shall be closed, and the system shall be isolated from all sources of pressure. When the test gauge is installed downstream of an appliance regulator, before the test is begun, open one valve and lower the pressure to 8 in in. water column (1.99 kpa kpa) so that the appliance regulator is in an open condition. The pressure in the system shall be measured over a period of 3 minutes with a manometer or with a pressure-sensing device designed and calibrated to read, record, or indicate a pressure loss due to leakage during the pressure test period. During the 3-minute period, a drop in pressure shall not occur. Substantiation: The conversion from 0.5 in. water column to 0.5 kpa is not correct. 0.5 in water column is equal to kpa. Note: Supporting material is available for review at NFPA Headquarters Log #80 Final Action: Reject ( (New) ) Recommendation: Add the following paragraph: Testing High Pressure Piping Systems for Gas Leakage. The high pressure piping system shall be proven by test to be leak-free by maintaining an air pressure of at least 80 psi (551 kpa) for a period of at least 10 min. Before the test is begun, the temperature of the air and the piping shall be approximately the same, and a uniform temperature shall be maintained throughout the test period. Leaks if observed, shall be located and corrected. Products containing ammonia or chlorine shall not be used for locating leaks. Defective material shall be replaced. Tests shall be conducted by any of the following methods: (1) The piping system shall be pressurized to a minimum of 80 psi (551 kpa), and the system isolated from all sources of pressure. The pressure in the system shall be measured with a pressure sensing device, calibrated to read in increments of not greater than 2 psi. During the 10 min period a drop in pressure shall not occur. (2) A bubble type leak detector shall be installed between the source of pressure and the piping system. The bubble detector shall not indicate any air flow for a period of 1 minute.

15 (3) As an alternate test, all connections in the high pressure piping system shall be tested for leakage with either soapy water or bubble solution. Substantiation: Remote cylinder applications (where a cylinder is mounted on each side of a fifth wheel bulkhead) have created the need for longer runs of piping on the high pressure side of the regulator. Current testing requirements were designed to address piping systems downstream of the propane regulator. This section adds requirements for testing the high pressure piping. Committee Statement: See Committee Action on (CP #6) Comment on Affirmative: HOPKINS: The Committee Statement is inaccurate because it refers back to Committee Action on Log #CP6 which has nothing to do with testing high pressure piping systems for gas leaks Log #117 Final Action: Accept ( 5.5 through ) Submitter: Matthew Brick, Skyline Corp. Recommendation: Delete Section 5.5 Fuel Oil Piping System. Delete the entire section through Substantiation: Are fuel oil requirements applicable for use in recreational vehicles per the definition of recreational vehicles? Fuel oil is for units set on sites with more permanence such as park trailers. Appliances need to be listed for use in recreational vehicles, are fuel oil appliances listed? LP gas is available nationwide and bottled for travel use. The elimination of fuel oil requirements will reduce the size of Chapter 5 by removing information that manufacturers do not use Log #12 Final Action: Reject ( ) Submitter: Ronald Mell, R E Mell and Associates Recommendation: Revise the first part of the first sentence to read: Fuel-burning appliances installed or intended to be used only outside the RV shall be listed for RV use. Substantiation: Adding this language would require all propane grills whether they are mounted on or just supplied loose with the RV to be listed for RV use. Committee Statement: This language is very broad and no specific standard has been referenced as being for RV use Log #13 Final Action: Accept ( ) Submitter: Ronald Mell, R E Mell and Associates Recommendation: Add a new last sentence as follows: Fuel burning appliances shall be so installed as to not obstruct any path to exit(s). Substantiation: Adding this language would preclude the mounting of BBQ grills, for example, under exit windows or locating grills that are mounted on swing-arms from swinging into a position that could block an entry door Log #15 Final Action: Reject ( ) Submitter: Ronald Mell, R E Mell and Associates Recommendation: Add the following new language and label to the end of this paragraph: Propane grills shall not be operated under an extended awning. A permanent warning label with the word WARNING with a minimum 1/4 in. (16 mm) high letters and body text with a minimum 1/8 in. (3 mm) high letters on a contrasting background shall be affixed in a visible location adjacent to the grill(s) and shall read as follows: WARNING DO NOT OPERATE THIS PROPANE GRILL UNDER AN EXTENDED AWNING FAILURE TO COMPLY COULD RESULT IN A FIRE OR PERSONAL INJURY. Substantiation: This added language will provide additional safety by warning the consumer of the potential fire risk when operating a LP-gas grill under an extended awning. Also the current ANSI Z21.58, Standard for Outdoor Cooking Gas Appliances does not allow any type of roof structure (noncombustible or not) above a listed LP-gas grill while it is in operation. This is due to the potential of grease fires and the related potential high plume of flame that can be created. Committee Statement: This requirement is outside the scope of NFPA 1192 because it is a consumer requirement that cannot be controlled by this standard Log #81 Final Action: Accept ( ) Recommendation: Revise the fifth sentence to read: Vent hood ducts shall be designed so that the duct outlet is located at such a point as to precludes the trapping of products of combustion. Substantiation: The change is editorial in nature. The language is changed to provide a clearer meaning Log #82 Final Action: Accept in Principle ( ) Recommendation: Add a new sentence at the end, as follows: Appliances with pilot lights shall have this information located so that it is easily readable after the appliance is installed. Substantiation: Only appliances with pilot lights need this information readable after the appliance has been installed. in Principle Revise as follows: Clearances, Input Ratings, Lighting and Shutdown Information on clearances, input ratings, lighting and shutdown shall be attached to the appliance. and located so that it is readable when the appliance is installed Appliances that require manual lighting of pilot lights shall have lighting and shutdown requirements located so that it is easily readable after the appliance is installed. Committee Statement: Clarifies the requirements and meets the submitters intent Log #83 Final Action: Accept in Principle ( ) Recommendation: Delete the term permanent in the first sentence. Every appliance shall be accessible for inspection, service, repair, and replacement without removing permanent construction or other fuel-burning appliances. Substantiation: The term permanent is unnecessary and is unenforceable since it is undefined. in Principle Revise the proposal as follows: Every appliance shall be accessible for inspection, service, repair, and replacement without removing permanent construction or other fuel-burning appliances.

16 Committee Statement: The definition of accessible already addresses the issue Log #84 Final Action: Accept ( ) Recommendation: Revise the first sentence to read: When used, privacy curtains that can be placed or swung closer to a cooktop/ range or wall furnace than the... Substantiation: The application of the requirement needs to apply to these specific listed appliances Log #85 Final Action: Accept ( ) Recommendation: Delete the word tag and replace it with the word label in the third sentence. The only exception to framing in or guarding such spaces shall be where such spaces will be necessary to allow access to shutoff valves or controls in order to comply with and , in which case the unguarded area shall have a warning tag label, posted in a readable location. Substantiation: The word label is more consistent in the text. The word tag is not commonly used Log #86 Final Action: Accept ( ) Recommendation: Add the term cooktop to the title and first sentence of the paragraph Vertical Clearances of Ranges and Cooktops. Ranges and cooktops shall have a vertical clearance between the cooking top and combustible material or metal cabinets in accordance with Table or the terms of their listings. Substantiation: The term cooktop refers to an appliance that only has burners. A range is both a cooktop and oven combination. Using cooktop in the requirement clarifies the intent Log #87 Final Action: Accept ( ) Recommendation: Add title to to read as follows: Exhaust Duct Installation Substantiation: Currently this code reference does not include a title and should have one to identify what the requirement is about Log #CP12 Final Action: Accept ( (New) ) Submitter: Technical Committee on Recreational Vehicles Recommendation: Move the note from Table to a new Substantiation: Manual of Style requires Notes with requirements to be in the body of the text Log #88 Final Action: Accept ( ) Recommendation: Delete the term permanent from the title Return Air Duct Permanent Unclosable Openings. Substantiation: The term permanent is unnecessary and is unenforceable since it is undefined Log #89 Final Action: Accept ( ) Recommendation: Delete the term permanent from the first sentence. Living areas not served by return air ducts and closed off from the return opening of the furnace by doors, sliding partitions, or other means shall be provided with permanent unclosable openings in the doors or separating partitions to allow circulated air to return to the furnace. Substantiation: The term permanent is unnecessary and is unenforceable since it is undefined Log #90 Final Action: Accept ( ) Recommendation: Delete the term permanent from the sentence. Each air conditioner shall be accessible for inspection, service, repair, and replacement. without removing permanent construction. Substantiation: The phrase without removing permanent construction is unnecessary. Also the term permanently is unenforceable since it is undefined Log #91 Final Action: Accept ( ) Recommendation: Revise the labels in (A), (B), (C), and (F) to reflect the actual labels used by the manufacturer inside the RVs. (A) The following warning: WARNING LP-Gas cylinders shall not be placed or stored inside the vehicle. LP-Gas cylinders are equipped with safety devices that relieve excessive pressure by discharging gas to the atmosphere. FAILURE TO COMPLY COULD RESULT IN DEATH OR SERIOUS INJURY (b) The following warning label has been located in the cooking area to remind the user to provide an supply of fresh air for combustion: WARNING IT IS NOT SAFE TO USE COOKING APPLIANCES FOR COMFORT HEATING. (1) Cooking appliances need fresh air for safe operation. Before operation: (1) (a) Open overhead vent or turn on exhaust fan. (2) (b) Open window. FAILURE TO COMPLY COULD RESULT IN DEATH OR SERIOUS INJURY (2) Unlike homes, the amount of oxygen supply is limited due to the size of the recreational vehicle, and proper ventilation when using the cooking appliance(s) will avoid dangers of asphyxiation. It is especially important that cooking appliances not be used for comfort heating, as the danger of asphyxiationʼs is greater when the appliance is used for long periods of time

17 (C) A warning label has been located near the LP-Gas container. This label reads as follows: WARNING DO NOT FILL CONTAINER(S) TO MORE THAN 80 PERCENT OF CAPACITY. FAILURE TO COMPLY COULD RESULT IN A FIRE OR PERSONAL INJURY (1) Overfilling the LP-Gas container can result in uncontrolled gas flow, which can cause fire or explosion. (2) A properly filled container will contain approximately 80 percent of its volume as liquid LP-Gas (F) The following label has been placed in the vehicle near the range area: WARNING IF YOU SMELL GAS: (1) Extinguish any open flames, pilot lights, and all smoking materials. (2) Do not touch electrical switches. (3) Shut off the gas supply at the container valve(s) or gas supply connection. (4) Open doors and other ventilating openings. (5) Leave the area until odor clears. (6) Have the gas system checked and leakage source corrected before using again. FAILURE TO COMPLY COULD RESULT IN EXPLOSION RESULTING IN DEATH OR SERIOUS INJURY Substantiation: Editorial - under item (B) in the first sentence change the existing term an to a. The label should read exactly how it is shown in existing paragraph The existing paragraph (B)(2) is not part of the existing warning label, so the designation (2) should be deleted and assigned a paragraph number during the MOS process. Therefore, the designation (1) becomes unnecessary within the label and should be deleted and existing (a) and (b) should be renumbered to (1) and (2). In (B), the information regarding failure to comply... was shown below the paragraph of explanation (2) and not as part of the label itself. The paragraph of explanation (2) was moved out of the label and the failure to comply statement moved into the label. In (C), the existing (1) and (2) statements of explanation were moved out of the label and a failure to comply statement added to the label. In (F) a failure to comply statement was added to reflect the actual text of the label used. Comment on Affirmative: MCTIER: Under (C) revise the first sentence of the warning label as follows: DO NOT FILL CONTAINER(S) TO MORE THAN THE MAXIMUM ALLOWED FILLING 80 PERCENT OF CAPACITY LIMIT Substantiation: In its original form this warning does not comply with U.S. DOT regulations nor with NFPA 58 for cylinders. Many cylinders are filled by the weight method rather than the volumetric method throughout the United States. The cylinders are designed to be filled to the 80 percent level when the temperature of the propane is at 40 F. The allowed weight of the propane liquid is based on a weight of.42 times the water capacity weight marked on the cylinder. Since propane liquid expands with increases in temperatures, it will be filled to a level above 80 percent when the temperature is about 40 F and it is filled by weight method that is allowed by DOT and NFPA 58. The second sentence below the main warning statement covers the approximate 80 percent filling level and therefore, allows both filling methods Log #122 Final Action: Reject ( (c) ) Submitter: Larry Budica, Fleetwood Enterprise, INc Recommendation: Delete LP-Gas container warning label which references 80 percent fill capacity. Substantiation: Introduction of OPD (overfill protection device) makes warning unnecessary. Committee Statement: The label provides an added level of safety that is necessary Log #16 Final Action: Reject ( 5.9.1(H) (New) ) Submitter: Ronald Mell, R E Mell and Associates Recommendation: Add the following label new (H): (H) The following label has been placed adjacent to the propane grill: WARNING DO NOT OPERATE THIS PROPANE GRILL UNDER AN EXTENDED AWNING FAILURE TO COMPLY COULD RESULT IN A FIRE OR PERSONAL INJURY. Substantiation: A 2005 code change proposal has been submitted under , which would require a warning label indicating that propane grills should not be operated under an extended awning. If the proposal ( ) is accepted, then this same information needs to be addressed in Section 5.9 under consumer information. Committee Statement: See Committee Statement on (Log #15) Log #92 Final Action: Accept in Part ( ) Recommendation: Modify the paragraph as shown: Each recreational vehicle shall have a label in accordance with Section 4.3 permanently affixed, in a visible location at or near each gas supply connection, or at the end of the piping. an exterior label in accordance with Section 4.3 with The label shall contain the word CAUTION with minimum 1/4 in. (6 mm) high letters and body text with minimum 1/8 in.

The label shall contain the with the word WARNING with minimum 1/4 in. (6 mm) high letters and body text with minimum 1/2 in. (3 mm) high letters on a contrasting background. and The label shall be affixed in a visible location adjacent to near the LP-Gas container that reads as follows: WARNING DO NOT FILL LP-GAS CONTAINER(S) TO MORE THAN 80 PERCENT OF CAPACITY. FAILURE TO COMPLY COULD RESULT IN A FIRE OR PERSONAL INJURY. (B) Each motor home or truck camper having exterior combustion air inlet(s) at a level below the roof shall have a permanent exterior danger label in accordance with Section 4.3. with The label shall contain the word DANGER with minimum 1/4 in. (6 mm) high letters and body text with minimum 1/2 in. (3 mm) high letters on a contrasting background. The label shall be affixed in a visible location near the gasoline filler spout and the LP-Gas container reading as follows: Substantiation: Text was added that provides additional clarification to the requirement. Deleted text was not needed or was unenforceable. in Part Accept the change but delete the word permanent Committee Statement: Permanent is not defined and not necessary in this section. Comment on Affirmative: MCTIER: In the warning label under (A) change LP-GAS CONTAINERS to PROPANE TANKS as all installed tanks must be filled by the volumetric method and therefore, the maximum 80 PERCENT CAPACITY meets the NFPA 58 requirements for propane tanks

18 Log #17 Final Action: Reject ( (New) ) Submitter: Ronald Mell, R E Mell and Associates Recommendation: Add the following new section as follows: Warning label for propane grills under extended awnings. LP-gas grills shall not be mounted where they can be operated under an extended awning. A permanent warning label with the word WARNING with a minimum 1/4 in. (16 mm) high letters and body text with a minimum 1/8 in. (3 mm) high letters on a contrasting background shall be affixed in a visible location adjacent to the applicable appliance(s) and shall read as follows: WARNING DO NOT OPERATE THIS PROPANE GRILL UNDER AN EXTENDED AWNING FAILURE TO COMPLY COULD RESULT IN A FIRE OR PERSONAL INJURY. Substantiation: A 2005 code change proposal has been submitted under , which would require a warning label indicating that propane grills should not be operated under an extended awning. If the proposal is accepted, then this same information needs to be addressed in Section 5.9.2, Required Marking. Committee Statement: See Committee Statement on (Log #15) Log #94 Final Action: Accept in Principle ( ) Recommendation: Make the following changes as shown: (A) Rear clearance line is defined as a plane extending between lines on each side of the vehicle that connect a point that is 8 in. (203 mm) above the ground on the vertical center line of the rearmost wheel spindle to the lowest point on the intersection of the rear wall and floor lines. Where the fuel tank is located between the chassis main rails, the rear point may be taken at the bottom of the main rail. Skid bars shall not be used to lower this point. (B) Front clearance line is defined as a plane extending between lines on each side of the vehicle that connect a point that is 8 in mm) above the ground on the vertical center line of the forward most wheel spindle to the lowest point of the front chassis cross member. The fuel tank shall be permitted to be located on a trailer A-frame if no part extends below the bottom of the A-frame members. Substantiation: The deleted language are definitions that need to be moved to the definition section of the standard. The two sections of deleted language are not requirements. in Principle Revise as follows: Revise the second sentence of as follows: The fuel tank and any of its attachments and fittings shall be located above rear and front clearance lines as specified in Revise (A) and (B) as follows: (A) Where the fuel tank is located between the chassis main rails, the rear point may be taken at the bottom of the main rail. Skid bars shall not be used to lower this point. (B) The fuel tank shall be permitted to be located on a trailer A-frame if no part extends below the bottom of the A-frame members. Add the following new definitions to Chapter 3 Rear Clearance Line. The plane extending between lines on each side of the vehicle that connect a point that is 8 in.

The plane extending between lines on each side of the vehicle that connect a point that is 8 in. (203 mm) above the ground on the vertical center line of the forward most wheel spindle to the lowest point of the front chassis cross member. Committee Statement: The submitters substantiation states that the deleted text are definitions but there is no proposal for including them in Chapter 3. The committee action accepts the revision to (A) and (B), revises the main paragraph to use the defined terms and adds the definitions to Chapter 3 in accordance with the submitters intent Comment on Affirmative: MCTIER: In the first sentence of (A) change may be taken to shall be permitted to be taken to comply with the MOS. This is just a reminder to the MOS task force. Also, the Committee might consider inserting a line drawing showing the fuel tank location Log #2 Final Action: Accept ( ) Submitter: Joel Creek, Skyline Corporation Recommendation: Delete text as follows: Hose to tube joints shall remain leak free when subjected to an internal pressure of 10 psig (69 kpa). Substantiation: is testing the same joint integrity as and 10 psig is in excess of pressures seen in fuel distribution systems on recreational vehicles. If a hose to tube joint passes the test in the joint will be sufficient for the minimal pressures seen on the inlet side of fuel-burning generators. Generator manufacturers state that the pressure at the fuel inlet of recreational vehicle generators must not exceed 1.5 psig Log #95 Final Action: Accept ( (New) ) Recommendation: Add a new paragraph as follows: All fuel transfer dispensing equipment shall only be accessible from the exterior of the vehicle, and renumber the rest of the section accordingly. Substantiation: This requirement adds safety and provides consistency with the State of Oregon requirements. Ballot Results: Affirmative: 18 Negative: 1 BLOOM: Fuel dispensing should not be allowed. Dispensing of flammable liquids by untrained person, minors without adequate supervision or accident cannot be prevented. Firefighters may not be aware that a fuel-dispensing tank is located under a trailer and are subject to severe burn injuries or death in the event of a rupture while aggressively extinguishing a fire Log #96 Final Action: Accept ( ) Recommendation: Revise as follows: These compartments shall be ventilated with openings having a minimum area of 1.7 in. 2 (1100 mm 2 ) within 2 in. of at both the top and bottom. Substantiation: This change to would then be consistent with the ANSI/RVIA 12V Standard paragraph 2-3 addressing ventilation requirements for auxiliary battery compartment installations. Comment on Affirmative: MCTIER: Add of the compartments to the end of the requirement to make sure that it is clear Log #97 Final Action: Accept ( ) Recommendation: Delete entire Substantiation: There is no reason to allow the ventilation within 2 in. of the top and bottom only, where compartment doors are used. RVIA is also sub-

This change to would then be consistent with the ANSI/RVIA 12V Standard paragraph Log #128 ( ) Final Action: Reject 2-3 addressing ventilation requirements for auxiliary battery compart- ment installations. Submitter: Jim Jollay, Char-Broil, Div, of W. C. Bradley Co Log #98 Final Action: Accept ( (New) ) Recommendation: Add a new as follows: These compartments shall not contain flame or spark producing equipment. Substantiation: (c)(4) addresses fuel tank compartments but not dispensing compartments, that could contain the hose and nozzle but not the tank. Ballot Results: Affirmative: 18 Negative: 1 BLOOM: See my Explanation of Negative on (Log #95). Recommendation: Revise text to read as follows: Fuel burning appliance intake and exhaust vents shall be located at lest 3 ft (0.9 m) from any point the fuel dispensing hose nozzle valve can reach if the intake or exhaust is above or at the same level as the valve. If any of such intake or exhaust is located below the valve with the hose extended fully horizontally, the location of the intake/exhaust shall not be in an area defined by the hose and a vertical line from the hose fully extended horizontally plus 3 ft (0.9 m). Substantiation: This change provides similar clearance as specified in for filler spouts. The wording in is such that it provides greater distance if an intake or exhaust is below the spout. The change proposed provides for similar clearance for the fuel dispensing hose nozzle valve. With the current wording if a 5-ft hose were extended fully horizontally and the three feet added the end would be 8 ft from the connection to the RV. This effectively means that an intake or exhaust could not be closer than 8 ft radius to the connection to the RV. With hose horizontal an intake or exhaust could be located 2 ft horizontally from the end of the nozzle as long as it is 4 ft below the horizontal plan. This change would assure that at no time would an intake/exhaust be horizontally closer than 3 ft to the valve for any valve position. See the following sketch for clarity

Bloom, Bloom Fire Investigation Recommendation: Add: Motor homes over 35 ft in length or bus-type motor homes having the door at the right side front shall be provided with at least one additional door-type exit. Substantiation: Window exits are not designed to safely or adequately provide safe egress to elderly occupants, handicapped, or persons covered by the Americans with Disabilities Act. Committee Statement: The substantiation does not match the recommendation. Ballot Results: Affirmative: 18 Negative: 1 BLOOM: A second exit should be mandatory on longer vehicles, and the committee should address the problem, despite the committee statement Log #104 Final Action: Accept in Part ( ) Recommendation: Delete the text as shown in the second sentence: The required smoke alarm shall be installed a minimum of 6 in. (152 mm) from all exterior walls measured edge to edge. and away from the direct flow of air from heat and air conditioning outlets. Substantiation: Many air conditioning outlets are of the rotary type and can spin a full 360 degrees. As written, this requirement would not allow a smoke detector to be installed. in Part Delete the entire second sentence of Committee Statement: The committee agrees with the submitter but also determined that the requirements were not necessary because they should be addressed in the listing of the product as required in the first sentence Log #105 Final Action: Accept in Principle ( ) Recommendation: Modify the requirement as shown: The fire extinguisher shall be installed in accordance with tits listing and Section 1.6 of NFPA 10 and shall be located within the recreational vehicle interior as near as practical to the within 24 in. of the opening of the primary means of exit. Substantiation: The current language is unenforceable. The proposed text adds a specific dimension and continues to meet the intent of the requirement. in Principle Revise proposal to read as follows: The fire extinguisher shall be located within the recreational vehicle interior in accordance with its listing and Section 1.5 of NFPA 10. Committee Statement: The reference to section 1.5 is the correct reference. NFPA 10 addresses location of the fire extinguishers and it is not necessary to do so in this section. Ballot Results: Affirmative: 18 Negative: 1 BLOOM: The present fire extinguisher location is universally known and can be easily accessed by anyone for a fire, which occurs inside or outside the RV Recommendation: Revise text to read as follows: Internal Combustion Engine Exhausts and Vehicle Wall Openings The terminus of Exhausts from internal combustion engines shall not terminate under the vehicle.

TABLE 2 Long Charge Time Short Charge Time Substantiation: Explanation of Automatic Generator Starting System (AGS) Small Unventilated Space 3,300 ppm 450 ppm Large Unventilated Space 220 ppm 30 ppm carbon-monoxide (CO) risk: Small utility engines, such as those used for RV engine generators, are usually applied without catalytic after-treatment of the exhaust. Untreated exhaust from spark-ignited gasoline, LPG, and natural gas RV engine generators contains potentially hazardous amounts of carbon monoxide (CO). When operated outdoors in open areas, exhaust and its CO component are dispersed. When operated in confined spaces, especially enclosed structures, exhaust and its CO component can accumulate to unhealthy and potentially lethal concentrations. When engine generators are manually started, they are customarily started and run under the direction and awareness of a responsible person who is (or should be) conscious of the engine generator CO hazards from their reading RV and engine generator manufacturersʼ literature. In the case of an engine generator that has an AGS feature, it is possible that starting and running will not be under the direction and awareness of a responsible person. If a low battery charge condition triggers an AGS start while an RV is garaged or stored in a confined area (such as between uses or while awaiting service or repair), an unhealthy or even lethal concentration of CO can accumulate. Subsequently, if a careless or unsuspecting person, child, or pet should enter the confined area, health injury or death are possible. The injury potential of CO for healthy persons is primarily a function of CO ppm (parts per million) concentration, length of exposure, and breathing rate. Generally available information identifies 1200ppm CO (0.12%) concentration as IDLH (immediate dangerous to life and health). Thirty minutes of continued exposure to the IDLH concentration is associated with irreversible health effects, inability to escape, and death. Higher concentrations are more immediately dangerous. 500 ppm has been identified as the level where long term exposure (several hours) can be lethal to humans. For RVʼs confined in unventilated spaces, and for reasonably expected charging circumstances, CO can accumulate to concentration levels that exceed the IDHL. See Table 1. TABLE 1 Long Charge Time Short Charge Time Small Unventilated Space 54,800 ppm 7,500 ppm Large Unventilated Space 3,650 ppm 500 ppm Assumptions used for these estimates are: - Typical 7kW fuel engine generator, without exhaust after-treatment, operating within EPA CO emissions limits hour Long charging session (large battery bank, low charge rate, and charging initiated at low state of charge). - 1 hour Short charging session (small battery bank, high charge rate, and charging initiated at a high state of charge). - Small unventilated space (9600 space volume less 3600 vehicle volume = 600 cu-ft net, for a 36 ft RV with minimal clearance for the opening of vehicle and storage compartment doors. RV sufficiently sealed that the net volume, not gross volume, is relevant). - Large unventilated space (90,000 cu-ft high ceiling space suitable for 4 stall RV service bay) Other information relevant to assessing CO risks; As a practical matter, the 0.3% limit would drive the selection of sophisticated fuel and exhaust systems such as what are currently used for automotive engines. When operating properly (and after a warm-up period), tailpipe CO level would be essentially nil, and the actual concentrations of CO should be less than indicated in TABLE Shutting the AGS system off (and shutting the engine generator off if running due to an AGS command) when parked means that a conscience manual decision is required to have AGS re-enabled or the engine generator restarted after parking. In usual circumstances, the result of a when parked shutoff means that; - AGS would be shut off and remain off when the RV is parked for storage or awaiting servicing. - Once restarted at an RV park location, AGS would remain available for as long as the vehicle was parked (or as long as the AGS system is capable of being enabled, whichever is shorter) This method interrupts the hazard sequence by limiting the amount of CO that can accumulate during confined engine generator running - whether starting/running unattended or attended by responsible persons. With AGS off, suppression of the external CO detectorʼs alarm is allowed to avoid its sounding as a result of exhaust from neighboring vehicle engines, campfires, or outdoor cooking appliances that are venting near the external detector-alarm. With AGS off, the allowed suppression of engine generator shutdown permits the typical RV circumstance, that is, engine generator control is manual and only the CO alert/control measure is the internal CO detector-alarm These markings and literature requirements are applicable to both sparkignited and diesel fueled engine generators. AGS should be shut off when RVʼs are stored to prevent unattended and unexpected starting. Safety Theory: The safety theory used to justify the proposed requirements is,...to provide safe operation for normal and reasonably expected abnormal circumstances.... It is reasonable to expect; - RVʼs will sometimes be parked in confined spaces with the AGS system enabled - even if there are manual, label, or display instructions to shut off AGS. - A person (or child or pet) who does not know if the AGS system is enabled, and/or does not know about possible AGS CO hazards, could occupy and be sleeping or napping in an RV or the confined area where the RV is parked or stored. - An RV could be left in a repair garage with AGS on, where it could run unattended, and possibly cause harm to persons unaware of the CO hazard in adjoining office areas or persons entering the storage or adjoining areas at a later time.
