Colonna Committee Scope: This Committee shall have primary responsibility for documents on the manufacture, selection, care, and use of garments and equipment used for protection of industrial personnel where there is potential for flash fire. Industrial personnel include workers who are potentially or may accidentally be exposed to hydrocarbon or combustible dust flash fires, and not electrical flashes. These documents do not cover fire fighters and other emergency services personnel. 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 Flash Fire Protective Garments is presenting two Reports for adoption, as follows: Report I: The Committee proposes for adoption, amendments to NFPA 2112, Standard on Flame-Resistant Garments for Protection of Industrial Personnel Against Flash Fire, 2001 edition. NFPA is published in Volume 12 of the 2004/2005 National Fire Codes and in separate pamphlet form. NFPA 2112 has been submitted to letter ballot of the Technical Committee on Flash Fire Protective Garments, which consists of 20 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 2113, Standard on Selection, Care, Use, and Maintenance of Flame-Resistant Garments for Protection of Industrial Personnel Against Flash Fire, 2001 edition. NFPA is published in Volume 12 of the 2004/2005 National Fire Codes and in separate pamphlet form. NFPA 2113 has been submitted to letter ballot of the Technical Committee on Flash Fire Protective Garments, which consists of 20 voting members. The results of the balloting, after circulation of any negative votes, can be found in the report

2 Log #8 Final Action: Reject (Title) RECOMMENDATION: Revise text to read as follows: Standard on Fabrics and Components for Flame-Resistant Garments for Protection of Industrial Personnel Against Flash Fire. SUBSTANTIATION: The standard does not specify garment performance requirements, it addresses fabric, thread, hardware, and labels (see Chapter 7). COMMITTEE STATEMENT: See Committee Action and Statement on Proposal (Log #3) Log #30 Final Action: Reject (Title) RECOMMENDATION: Revise title of document to: Standard on Thermal protective Garments for Industrial Personnel for Survival and Escape from Hydrocarbon Flash-Fires SUBSTANTIATION: 1. NFPA 2112 goes beyond testing fabric flameresistance to the point of predicting thermal protection. 2. Products compliant with this standard do not necessarily completely protect in all flash fire situations, but are intended to allow time to escape and mitigate thermal injuries to a survival level. COMMITTEE STATEMENT: The Committee believes that the current title best reflects the scope of the document. The Committee also believes that the proposed title goes beyond the scope of the committee, with the inclusion of the terms survival and escape Log #3 Final Action: Accept in Principle (1.1) RECOMMENDATION: Revise text to read as follows: 1.1 Scope. This standard shall specify the minimum design, performance, certification requirements, and test methods for fabrics and components of flame-resistant garments for use in areas at risk from flash fires. SUBSTANTIATION: The standard does not specify garment performance requirements, it addresses fabric, thread, hardware, and labels. (See Chapter 7). in Principle Revise the scope statement to read as follows: 1.1 Scope. The standard shall specify the minimum performance requirements and test methods for flame-resistant fabrics and components and the design and certification requirements for garments for use in areas at risk from flash fires. COMMITTEE STATEMENT: This accomplishes the intent of the submitter Log #CP3 Final Action: Accept (1.2) SUBMITTER: Technical Committee on Flash Fire Protective Garments RECOMMENDATION: Modify as follows: 1.2.1* This standard shall provide minimum requirements for the design, construction, evaluation, and certification of flame-resistant garments for use by industrial personnel, with the intent of not contributing to the burn injury of the wearer, providing a degree of protection to the wearer, and reducing the severity of burn injuries resulting from accidental exposure to hydrocarbon flash fires. A Users are cautioned that flammable clothing can contribute to the severity of burn injuries through their ignition and continued burning after exposure to flash fire. SUBSTANTIATION: The Committee wants to reinforce the fact that clothing meeting this standard is less likely to contribute to burn injuries Log #9 Final Action: Accept (1.3) The minimum requirements identified in this standard are not intended to meet all the protection needs of a user in areas at risk from flash fires. Users shall refer to NFPA 2113 for conducting the appropriate hazard assessment to identify the in-use area s minimum protection requirements. SUBSTANTIATION: NFPA 2112 sets minimum standards for participating in the flash fire protective garment arena. It does not (and should not), however, establish a users need for minimum protective requirements. The addition of the proposed text will direct users to the appropriate standard (NFPA 2113) to make this determination Log #CP2 Final Action: Accept (1.3.2) SUBMITTER: Technical Committee on Flash Fire Protective Garments RECOMMENDATION: Modify Application as shown: 1.3.2* This standard shall not apply to protective clothing for wildland fire fighting, technical rescue, structural fire fighting, proximity fire fighting, or any other fire-fighting operations or hazardous materials emergencies. This standard shall not apply to single-use or limited-use garments. This standard shall not apply to protection from electrical flashes, radiological agents, biological agents, or hazardous materials. SUBSTANTIATION: The application section has been modified to clarify the Committee s intent that single-use and limited-use garments should be addressed in a separate set of documents and are not considered within the scope of NFPA Log #28 Final Action: Accept ( ) RECOMMENDATION: Change edition of AATCC 135 to 2003 and AATCC 158 to SUBSTANTIATION: The referenced standard has been revised since the publication of the 2001 edition of NFPA Log #27 Final Action: Accept ( ) RECOMMENDATION: Change edition of ASTM F 1930 to SUBSTANTIATION: The referenced standard has been revised since the publication of the 2001 edition of NFPA Log #31 Final Action: Reject ( ) RECOMMENDATION: Add ASTM F 1154, Standard Practice for Qualitatively Evaluating the Comfort, Fit, Function and Integrity of Chemical Protective Suit Ensembles. SUBSTANTIATION: NFPA 2112 does not address the pretest conditioning of garments that are not intended to be laundered or dry-cleaned. This proposed practice provides a practical wear-conditioning procedure.

Both NFPA 2112 and NFPA 2113 use the first sentence only of the preferred definition.

4 The preferred definition of garments. The preferred definition of hardware includes proximity protective ensemble which is not applicable to flash fire protective garments. The preferred definition of hazardous material is one that is broadly applicable to all hazardous material incidents and is not directed toward personal protective clothing - i.e., protection from inhalation, ingestion, dermal exposures (whether absorption or contact) and is therefore not applicable to the Log #13 (4.1.6 (New) ) Final Action: Accept scope of this standard. The preferred definition of lining indicates permanent attachment, which is not always applicable to linings for flash fire protective garments. The Committee accepted the preferred definition of Product Label, but added an annex to this definition. The second sentence of the secondary definition currently found in this standard is added as an annex item to this definition. The preferred definition of reinforcement is not specific as to the purpose of the extra layer of material and needs to have that additional wording to clearly indicate the purpose for the reinforcement. The Committee accepted the preferred definitions for Emblem (with modification), Interlining, and Product Label (with modification). RECOMMENDATION: Add new text to read: Manufacturers shall not claim compliance with a portion(s) or segment(s) of the requirements of this standard and shall not use the name or identification of this standard, NFPA 2112, in any statements about their respective product(s) unless the product(s) is certified as compliant to this standard. SUBSTANTIATION: Certain manufacturers in industry have made claims for compliance with or meeting the requirement of NFPA 2112 without fulfilling all requirements of the standard, including certification, as specified in Log #32 Final Action: Accept in Principle (3.3 Limited-Use Garment (New) ) RECOMMENDATION: Add new text to read: Limited-Use Garment A garment intended to be used until damaged or contaminated, but not intended to be decontaminated for re-use, to be drycleaned or to be laundered. A disposable garment is a limited-use garment worn only once. SUBSTANTIATION: NFPA 2112 does not address the pre-testing conditioning of garments that are not intended to be laundered or dry-cleaned. This addition defines this class of garments. in Principle Add a new definition as follows: 3.3.x Limited-Use Garment. A garment whose service life is limited by the manufacturer to a specified number of wear cycles and does not meet the testing requirements of this standard. COMMITTEE STATEMENT: The Committee supports the need for this definition as proposed but has modified it to differentiate limited-use from the single-use concept added by action on another proposal Log #18 Final Action: Accept in Principle (3.3.x Single-Use Garment (New) ) 3.3.x* Single-Use Garment. A garment that is designed to be used one time and then disposed of. A.3.3.x Single-Use Garment. What constitutes a use will be defined by the garment manufacturer. A single use could include unpacking, or one donning, or one wearing while responding. In the absence of any manufacturer s specific information, one use should be considered any one-time wearing of the garment. Inspection of any garment should be conducted in accordance with the manufacturer s instructions and should assess the overall condition and suitability of an item for a specified use. use garments. The proposed change adds the definition of a single use garment. in Principle Add new text as follows: 3.3.x* Single-Use Garment. A garment that is designed to be used one time and then disposed of. A.3.3.x Single-Use Garment. What constitutes a use will be defined by the garment manufacturer. A single use could include unpacking, or one donning, or one wearing while responding. In the absence of any manufacturer s specific information, one use should be considered any one-time wearing of the garment. Inspection of any garment should be conducted in accordance with the manufacturer s instructions and should assess the overall condition and suitability of an item for a specified use. COMMITTEE STATEMENT: The Committee deleted the text as indicated since response applications have been excluded from the standard and the inspection statement proposed in the annex is not applicable commentary for this definition Log #14 Final Action: Accept in Principle in Part (4.1.7, and (New) ) RECOMMENDATION: Add new text to read: The certification organization shall not certify any flame-resistant garments to the 2001 edition of this standard on or after 1 February The certification organization shall not permit any manufacturer to label any flame-resistant garments as compliant with the 2001 edition of this standard on or after 1 February The certification organization shall require manufacturers to remove all certification labels and product labels indicating compliance with the 2001 edition of this standard from all flame-resistant garments that are under the control of the manufacturer on 1 February The certification organization shall verify this action is taken. SUBSTANTIATION: Specific language is needed to control the expiration of the 2001 edition and practices within industry for citing both the old and new standards. A grace period of 6 months is allowed for manufacturers to comply with the new edition assuming a promulgation date of August After that time, no product should be certified to the old edition of NFPA in Principle in Part Add new text to read: The certification organization shall not certify any flame-resistant garments to the 2001 edition of this standard on or after 1 February August The certification organization shall not permit any manufacturer to label any flame-resistant garments as compliant with the 2001 edition of this standard on or after 1 February August The certification organization shall require manufacturers to remove all certification labels and product labels indicating compliance with the 2001 edition of this standard from all flame-resistant garments that are under the control of the manufacturer on 1 February The certification organization shall verify this action is taken. COMMITTEE STATEMENT: The Committee changed the date from a 6 month period for compliance to 12 months to allow adequate time for implementation.

COMMITTEE STATEMENT: The Committee believes that single-use and limited-use garments should be addressed in a separate set of documents and are not considered within the scope of NFPA The Committee has submitted a request to the NFPA Standards Council to obtain approval to develop new documents where this subject can be covered Log #1 Final Action: Accept ( ) RECOMMENDATION: Change sensor schematic to show only one hole located in the center of the disk, and change the accompanying text: Connect 4 1 T/C in to center of disk. parallel, silver soldier connections. Bring the T/C common lead out of center hole of support. Secure sensor into support with three or four sewing thread pins cut to 9.5 mm (3/8 in.) long. SUBSTANTIATION: The calorimeter construction detailed in (multiple Type J T/C s) violates the law of intermediate materials in thermoelectric circuits Log #4 Final Action: Accept ( ) RECOMMENDATION: Revise with the following text: The recorder shall be any strip chart recorder with full-scale deflection of at least 150 C (300 F) or 10 mv and sufficient sensitivity and scale divisions to read exposure time to ±0.1 second, or alternatively, an equivalent automated data acquisition system meeting or exceeding the sensitively and accuracy requirements of the strip chart recorder shall be permitted to be used instead of a strip chart recorder. The sensor data acquisition system shall be able to record temperatures to at least 150 C. The temperature acquisition system shall have at least a resolution of 0.1 C and an accuracy of ±0.75 C. SUBSTANTIATION: A strip chart recorder is inadequate for the determination of heat flux from the temperature response of the sensor. Cold junction compensation, linearization, and accounting for the temperature dependency of the copper heat capacity is beyond its capability Log #10 Final Action: Reject (8.2.5) RECOMMENDATION: Revise text to read as follows: TPP testing shall be conducted on three separate sample test suites containing multiple specimens measuring 150 mm ± 5 mm x 150 mm ± 5 mm (6 in. ± 1/4 in. x 6 in. ± 1/4 in.) and shall consist of all layers representative of the garment to be tested. The specific number of test specimens in a single test suite will vary according to the materials being measured A minimum of three sample test suites is required for determination of a thermal protective performance (TPP) rating The determination of a single sample test suite thermal protective performance value requires multiple sample specimens and an iterative exposure technique mm (5.25 in.)

Follow the procedure outlined in for samples where the approximate thermal protective performance value is known (e.g., repeats of sample test suites as identified in above) Test Exposure of samples with unknown thermal protective performance values - A method of successive halving is employed to determine the thermal protective performance value Place the copper calorimeter/specimen assembly prepared in , which is initially at room temperature, into the specimen holder testing location Place the manual or mechanically operated shutter device over the heat source to completely block the heat then place the copper calorimeter/ specimen assembly over the shutter (exposure configuration) Start the data acquisition system, remove the shutter, and collect the copper calorimeter sensor information Terminate the sample exposure (replace the shutter and move the specimen holder/calorimeter assembly away from the heat source) after the total accumulated heat energy as measured by the calorimeter meets/exceeds the shutter and immediately move the copper calorimeter/exposed specimen assembly away from the heat source (location free of drafts or other heating/ cooling sources) Continue to acquire calorimeter data for at least 30 seconds after removing the assembly from the heat source and until the heat stored in the specimen has been released (into the calorimeter and environment). Acquisition times greater than 30 seconds after removal may be required on heavy single and multilayer specimens From the measured calorimeter response, determine if a predicted second-degree burn injury occurred (total measured heat energy exceeded the Stoll value at any time during the exposure or cooling cycles) If a second-degree burn injury is not predicted, determine a new exposure time value that is halfway between the just completed t trial value and the higher previous exposure time value (for the first time through, select a higher previous exposure time value as 1.5 x t max ). assign t trial time to this value and repeat Sections through If a second-degree burn injury is predicted, determine a new exposure time value that is half way between the just completed t trial value and lower previous exposure time value (for the first time through, the lower the following criteria: previous exposure time value with be the previous t trial value determined in J/cm = x t i ). Assign t trial time to this value and repeat Sections Where t i is the time value in seconds of the elapsed time since the initiation through of the thermal energy exposure (shutter removed). The exposure time value, t max If the difference between the current t trial and the previous t trial that satisfies this equation represents the approximate second-degree predicted burn injury point for the continuous heating of the sample specimen Allow the specimen holder/calorimeter assembly to cool to room temperature before dissembling and removing the exposed specimen. Remove the shutter and also allow it to cool to room temperature Prepare another test specimen as outlined in Determine the exposure time trial value for the next iterative exposure by dividing t max (determined in ) by two, trial exposure time, t trial = t max / Place the copper calorimeter/specimen assembly prepared in , which is initially at room temperature, into the specimen holder testing location Place the manual or mechanically operated shutter device over the heat source to completely block the heat then place the copper calorimeter/ specimen assembly over the shutter (exposure configuration) Start the data acquisition system (collect the copper calorimeter sensor information), remove the shutter, and expose the copper calorimeter/new specimen assembly to the heat source for t trial seconds. Replace the shutter and immediately move the copper calorimeter/exposed specimen assembly away from the heat source (location free of drafts or other heating/ is 0.5 seconds, then the thermal protective performance value for this test suite is: TPP value, J/cm 2 = current t trial, seconds x exposure heat flux value, kw/ m 2 /10. SUBSTANTIATION: The current TPP method measures direct flame impingement heat transfer only. It neglects accounting for the thermal energy that remains in the specimen and is subsequently transferred to the sensor after the heat source is removed. The proposed text accounts for the burn injury potential of the heated sample. COMMITTEE STATEMENT: The Committee rejects the proposal at this time to establish a new test method because the current criteria in the standard would be inconsistent with the proposed test method were it to be included. No performance criteria has been provided with this submission. To facilitate further study of this matter, a task group has been formed and charged with development of the method and corresponding criteria. cooling sources) Continue to acquire calorimeter data for at least 30 seconds after removing the assembly from the heat source and until the heat stored Log #2 Final Action: Accept in Principle in the specimen has been released (into the calorimeter and environment).
