1 Title: McIntosh Hydroblasting and High Pressure Cutting Procedure Site Procedure No.: MC Page: 1 of 17 Preparer: B. Turner Owner: M. Ware Approver: G. Vann EHS Specialist EHS Team Leader Site Manager 1. Purpose The purpose of this procedure is to establish guidelines for all contractors performing hydroblasting, water cutting or any other work involving the use of high pressure water on the BASF McIntosh, Alabama site. This procedure is designed to improve communications between site operations and contractors providing the hydroblasting/cutting services as well as other contracted or contractor employees who may be affected by the hydroblasting/ cutting operation. 2. Definitions 2.1. Anti-Withdrawal Device An indexing device that attaches to the equipment or piping being cleaned that allows the flex lance to pass through but prevents the withdrawal of the nozzle Automation Automatically controlled operation of an apparatus, process or system by mechanical or electronic devices that take the place of human labor. Examples are automated feed, automated indexing, and automated manipulation or any of these combinations. Non-automated examples include shot gunning and hand fed lance assemblies. Nonautomated activities require a formal review and approval Back Thrust Force The force produced by a jetting gun and the amount of force the operator must withstand. Back Thrust (lbf) = x flow rate x pressure 2.4. Double Trigger Gun A high pressure water gun that requires the operator to activate two triggers, one with each hand, to generate a high pressure Water Jet Dump System Valve A quick response valve that can be triggered by the hydroblasting technician to cut off the high pressure water stream DuraSafe Shotgun A shotgun so designed as to require the operator to use both hands to operate the gun. This type of shot gun is operated in the same manner as a double trigger gun Flexible Lance A flexible tube or hose section carrying water to the nozzle. It is normally located between the trigger or control valve and the nozzle.

2 Procedure No.: MC Page: 2 of Foot-Controlled Valve A valve that dumps the pressure of the system by activating (releasing) a foot pedal High Pressure Hose A flexible hose that can carry water and/or other fluids from one part of the high pressure water jet system to another High Pressure Water Cutting The use of pressurized water, typically between 30,000 and 40,000 psi, usually with the addition of solid particles used as abrasives, to penetrate into the surface of a material for the purpose of cutting that material Hydroblasting The process of cleaning surfaces with high pressure water, at or above 5,000 psi or greater than 5 gpm, with or without the addition of other liquids or solids Hose Shroud A length of flexible material usually formed into a tube around a hose end coupling or across the connection to the jetting gun. The shroud provides the operator holding the gun some instantaneous protection from the high pressure water to prevent injury from a hose or fitting failure Indexing The act of positioning or adjusting the cleaning nozzle into the device or equipment being cleaned Lancing An application whereby a hose fitted with a nozzle is inserted into and retracted from the interior of a tube of a pipe or tubular product Moling An application whereby a hose fitted with a nozzle is inserted into and retracted from the interior of a tube and has a self-propelling nozzle for cleaning the internal surfaces of pipes or drains Nozzle A device with one or more orifices through which the water discharges from the system. The nozzle restricts the area of flow of the fluid, accelerating the water to the required velocity and shaping it to the required flow pattern. Nozzles are also commonly referred to as bits, tips or orifices Pressure Pump A pump that will increase the pressure of water delivered to it and deliver it into a common manifold to which either flexible hoses or rigid tubing connecting to lances and nozzles are attached. These pumps can be either mobile or permanently mounted and are most often of a positive displacement plunger style that will provide a constant flow of water at a given speed of rotation.

3 Procedure No.: MC Page: 3 of Pressure Washing The process of cleaning surfaces with high pressure water, routinely below 5,000 psi and 5 gmp or less, with or without the addition of other liquids or solids Rigid Lance A rigid tube carrying water to the nozzle manifold usually referred to as stiff lance Roto Jet A hydroblasting nozzle that projects a 2 or 3 dimension high pressure water stream Shotgunning A hand held application whereby an assembly of a lance and a nozzle can be manually manipulated in virtually all planes of operation Stinger A short section of rigid tubing used on the nozzle end of the flex lance that prevents the lance from reversing directions inside the piping or equipment Snorkel A section of pipe or tubing extending from the anti-withdrawal device or feeding mechanism within 1 or less of the tube sheet which contains the lance and tip and guides it into the pipe or tube being cleaned Water Jet A rapidly moving stream of water of different shapes and types exiting from a nozzle orifice. The speed of the jet depends on the pressure drop across the nozzle orifice Whip Hose The short piece of hose that attaches directly to the shotgun and is at least 6 in length and made of double wire braiding Whip Lock/Whip Check Restrainer attached at any point where two hoses are joined. This device is used to control the movement of a pressurized hose if it becomes uncoupled Working Pressure The maximum pressure, as recommended by the manufacturer, at which a component is to be used. 3. Scope This procedure applies to the BASF McIntosh site. This procedure applies to all personnel involved in or affected by hydroblasting and high pressure water cutting on the McIntosh site.

4 Procedure No.: MC Page: 4 of Procedure 4.1. McIntosh Site Implementation - Hydroblasting The BASF McIntosh site is committed to improving the safety of all hydroblasting operations performed on the site. As much as conceivably possible, manual hydroblasting activities such as shotgunning, shall be replaced by automated cleaning equipment. Due to the corporate requirement for hydroblasting automation, any manual hydroblasting work must go through a formal review and approval each and every time a non-automated cleaning operation occurs. Formal review and approval shall be documented via the Change Management database. NOTE: All pressure washing shall be performed under, at a minimum, a safe work permit General Safe Work Practices - Hydroblasting When all other measures have been exhausted and automation is not feasible, a formal review shall be performed for hydroblasting shotgunning and hand fed lancing in accordance with section 4.8. of this procedure. NOTE: A pre-job BASF required checklist shall be completed prior to the beginning of any job. This checklist must be completed jointly by the hydroblasting supervisor and a BASF supervisor and signed off by the hydroblasting crew supervisor and a BASF supervisor. See Attachment 1 for this checklist During and at the completion of the job, the hydroblasting crew is responsible for controlling debris/waste and maintaining good housekeeping practices on the job site. This includes, but is not limited to, the elimination of slip, trip and fall hazards including proper hose placement and proper disposal of trash, contaminated PPE and chemical/product wastes generated from the cleaning service The hydroblasting company shall comply with all BASF and state and federal environmental policies, laws and procedures Barricading of the pump(s) and the job site hazards is required on every job and should be placed accordingly to restrict unauthorized personnel from entering the work area. Barricading should also include the end point of the operation. The hydroblasting company shall provide barricade tape that reads Danger Hydroblasting or identifies in some clear and concise manner that the area is a hydroblasting area. The area can be barricaded with red chain(dependent upon high pressure hydroblasting water cutting or pressure washing-red) or yellow chain (pressure washing as defined in this procedure at 2.17-YELLOW). A tag on the barricade should identify the hydroblasting supervisor or person of authority (this can be a trained attendant) for the cleaning job. Permission to enter the barricaded work area should be granted only from the approval of the hydroblasting supervisor, person of authority or trained attendant(s). The barricaded area shall

5 Procedure No.: MC Page: 5 of 17 encompass all of the hoses in use at the hydroblasting work area. When working above ground level, barricades will be required below At least one wheel on any staged mobile equipment must be double chocked against accidental movement when parked on location Whip locks shall be used on all pressured hose connections to prevent the hose from whipping in the event the coupling breaks or becomes disconnected A trained attendant is required to be present for all operating equipment at all times. The attendant must be close enough to shut down the equipment in an emergency All jobs require a line-of-sight between the equipment attendant and the hose end equipment operator. If direct line-of-sight cannot be achieved, radio communication or use of an additional trained attendant for line-of-sight must be used to assist in quickly de-energizing the equipment All hoses should be routed and protected in a manner that prevents vehicular damage and personnel exposure to the hoses. When possible, roadways should be barricaded for vehicular and pedestrian traffic where hoses cross roadways. See above All personnel, when the system is under pressure, shall not be within 6 of pressurized connections unless the equipment is shielded or guarded in some manner (including weep holes) To help prevent injuries from a lance or line mole hose reversing under hydraulic pressure, it is required to clean the tube sheet and the first 6 (inches) of the tubes or the first 24 of the piping with a shotgun connected to an indexer or similar automated device, so that proper engagement with the lance or line mole can be achieved before high pressure is applied All equipment being cleaned shall be adequately shielded against flying debris/chemicals and high pressure water stream that could pose a potential injury or exposure to someone. Examples include but are not limited to plywood, metal sheeting or water blast curtains Hydroblasting equipment shall be grounded per site and hydroblasting company requirements An anti-withdrawal device must be used on all flex lances, rigid lances and line moling jobs. The anti-withdrawal device must be securely attached to the equipment being cleaned.

6 Procedure No.: MC Page: 6 of When flex lancing or line moling, the lance/hose must have a hard stop for the maximum length of travel All non-rotating equipment high pressure hose assemblies must include whip checks to protect personnel from excessive movement of hoses in case of a hose rupture or a blown end fitting Hose shrouds shall be designed so that they can withstand the full rated service pressure of the system for maximum personnel protection and are not intended to only perform water management duties in the event of a hose rupture The Back Thrust Force for a hydroblasting operator shall not be greater than 1/3 of his/her body weight. Rotating operators in and out of the job is also recommended because of the physical demand of the job duration Only the nozzle operator shall manually control the dump system. When a foot valve is used, it must be placed within a frame that will guard the valve from being accidentally operated and that is sturdy enough, so that it will not accidentally moved or knocked over when it is used. Where the water dumps through a dump system and is not immediately released to the open air, but passed into a dump line, the dump line must be secured, so that it does not whip when activated. Also ensure that the dump system is clear of obstructions Indexing is not allowed while the lance is energized unless the indexing is automated and controlled from a remote location General Safe Work Practices - Hydroblasting Equipment Requirements All high pressure pumps provided by the hydroblasting company must be equipped with a relief system that allows for the relief of the pressurized system. This pressure must be set at 1.2 times the pressure of the lowest rated component of the system operating at the time All rigid or stiff lance assemblies shall include use of a minimum 3 (feet) shroud to protect the employee(s) handling the end of the rigid or stiff lance. The construction of the shroud, for example such as a double S.S. braided shroud, shall be sufficient enough to help ensure the safety of the employee against serious injury from a potential hose rupture. A visual inspection shall be made of the shroud prior to each use. The hose shroud shall be inspected for inner and outer integrity, such as excessive wear and breakdown of reinforcement wire braiding, at a minimum on a quarterly basis. These quarterly inspections must be documented and records made available

7 Procedure No.: MC Page: 7 of 17 to the BASF McIntosh site upon request. Prior use inspections shall be documented on a pre-work checklist before each job Anti-withdrawal devices used on tube sheets during rigid or flex lancing, must include the use of a snorkel device that does not exceed 1 clearance from the tube sheet. In vertical tube sheet applications, to prevent the potential of a water cut to the foot, that gap between the snorkel and the tube sheet, must be protected by a physical barrier to prevent contact with the lance operator. Among these potential devices is a 4 X 4 X 12 piece of angle iron or a 2 X 4 X 12 board. NOTE: This shielding is not required if indexing is automated In addition to use of anti-withdrawal devices when line moling, a stinger must be attached to the end of the nozzle which is at least 1.5 times longer than the I.D. of the piping being cleaned. The rigidity of the compression fitting and nozzle length can be included in the overall stinger length requirement. NOTE: Special consideration shall be given to tees in the line being cleaned when the tee in the line is larger than the main line being cleaned. Additional length of stingers maybe required to prevent accidental reversal of the line mole assembly in the piping When performing line moling operations using a self-propelled nozzle as described in section 2.15, controlled by a foot-controlled valve as described in section 2.8 with an anti-withdrawl device as described in section 2.1 in place of no hands-on twisting of the moling line while under pressure this will be considered automated. However, if a line moling operation has to be manually turned while under pressure, this is NOT automated and will require an MOC for the work to be performed All high pressure hoses and flex lances used for line moling must be marked at a minimum 24 from the end compression fitting. This visual marking will minimize the potential for a serious water cut when the line mole on the hose end is exiting toward the end of the pipe. NOTE: This is not applicable with automated processes All shotgun whip hoses must be shrouded to protect the shotgunner against accidental rupture of the whip hose. Shotgun shrouds must be constructed, for example such as of double S.S. braided material, in a manner that protects the shotgunner against a serious water cut. The protective shroud must be a minimum of 6 in length. The whip hose shroud shall be visually inspected prior to each use. The hose shroud shall be inspected for inner and outer integrity, such as excessive wear and breakdown of reinforcement wire braiding, at a minimum on a quarterly basis. These quarterly inspections must be documented via a company specific checklist or other record and records made available to the BASF McIntosh site upon request. Prior use inspections shall be documented on a pre-work checklist before each job. Hoses must have tags/bands, etc. to reflect the current testing period.

8 Procedure No.: MC Page: 8 of The length of the shotgun shall be a minimum of 66 in overall length from the shoulder brace (butt stock) of the gun to the end of the nozzle when used in a manual (non-automated) application High pressure hose and fittings, connection fittings and couplings shall be manufactured to be compatible with the hose. All components of the system should be compatible with the service pressure of the pump and only fittings marked with the maximum allowable working pressure (MAWP) shall be used. Fittings designed for pressure less than the service pressure of the pump shall never be used in a higher pressure application. NPT or pipe thread connections shall not be used at pressures greater than 15,000 psig Hydroblasting shotguns require double triggers or safety latched triggers which require disengaging the safety latch. This requires the use of both hands before the trigger can be engaged When roto jet nozzles are in operation inside a vessel, the entry point where the hose enters the vessel must be securely covered to prevent the jet from exiting the vessel. Suspending the roto jet nozzles with a rope is not acceptable McIntosh Site Implementation High Pressure Water Cutting Requirements The BASF McIntosh site is committed to improving the safety of all high pressure water cutting operations performed on the site. As much as conceivably possible, manual high pressure water cutting activities shall be replaced by automated cutting equipment. Due to the corporate requirement for automation, any manual high pressure cutting work must go through a formal review and approval each and every time a non-automated cutting operation occurs. Formal review and approval shall be documented via the Change Management database. NOTE: All high pressure cutting shall be performed under a safe work permit During and at the completion of the job, the hydroblasting crew is responsible for controlling debris/waste and maintaining good housekeeping practices on the job site. This includes, but is not limited to, the elimination of slip, trip and fall hazards including proper hose placement and proper disposal of trash, contaminated PPE and chemical/product wastes generated from the cleaning service The hydroblasting company shall comply with all environmental policies and procedures Barricading of the pump(s) and the job site hazards is required on every job and should be placed accordingly to restrict unauthorized personnel from entering the work area. Barricading should also include the end point of the

9 Procedure No.: MC Page: 9 of 17 operation. The hydroblasting company shall provide barricade tape that reads Danger Hydroblasting. The area can be barricaded with red chain(dependent upon high pressure hydroblasting water cutting or pressure washing-red) or yellow chain (pressure washing as defined in this procedure at 2.17-YELLOW). A tag on the barricade should identify the hydroblasting supervisor or person of authority (this can be a trained attendant) for the cleaning job. Permission to enter the barricaded work area should be granted only from the approval of the hydroblasting supervisor, person of authority or trained attendant(s). The barricaded area shall encompass all of the hoses in use at the hydroblasting work area. When working above ground level, barricades will be required below Job plans must be established and approved by the responsible BASF supervision for all high pressure cutting work before work execution. At a minimum this shall include basic job steps, parameters and safeguards All high pressure water cutting will be through the use of an automated track system Manually held cutting devices are not permitted All hoses shall be inspected prior to use and pressure tested on a quarterly basis (minimum). Records of inspections/testing shall be maintained by the hydroblasting company, contract/contractor companies using hydroblasting equipment and BASF personnel using hydroblasting equipment. Inspection/testing shall be documented and available for BASF review when requested. Tags, bands, etc. shall be used to indicate hose inspection/testing dates Track cutting systems will be firmly attached to include a secondary method of attachment Personnel must remain 10 from the cutting head Prior to starting the cut, ensure that the portion of the structure to be cut is properly supported so that it will remain suspended when the cut is finished. If the portion of the structure to be cut is not rigged, determine with the customer contact how much of the structure to leave uncut until the support is in place The largest orifice to be used for hydro cutting is.022 inches McIntosh Site Implementation Pressure Washing (Below 5000 psi) The BASF McIntosh site is committed to improving the safety of all pressure washing operations performed on the site. While pressure washing activities are generally

10 Procedure No.: MC Page: 10 of 17 performed at a much lower pressure than hydroblasting or high pressure water cutting activities, there are still inherent dangers associated with this work that shall be addressed by personnel responsible for authorizing the work and personnel performing the work. All personnel performing pressure washing work shall be properly trained on the equipment which shall be operated by the personnel. These personnel include BASF personnel, hydroblasting company personnel and any other contractor, contract or sub-contractor personnel performing this type of pressure washing work at the McIntosh site. While pressure washing is typically performed at lower service pressures, the below special precautions must be followed. NOTE: All pressure washing shall be performed under a safe work permit During and at the completion of the job, the pressure washing crew is responsible for controlling debris/waste and maintaining good housekeeping practices on the job site. This includes, but is not limited to, the elimination of slip, trip and fall hazards including proper hose placement and proper disposal of trash, contaminated PPE and chemical/product wastes generated from the cleaning service The pressure washing crew shall comply with all environmental policies and procedures Pressure washing does not include line moling or lancing type activities Pressure washing units shall be inspected prior to use and operated per the manufacturer s recommendations. Periodical system inspections shall follow the manufacturer s recommendations or site/company procedures. Alterations or modifications are not permitted. The maximum operating pressure of the pressure washer shall be posted/available on the machine PPE shall address the hazards associated with pressure washing, which could include but is not limited to water cuts, chemical contact, noise, respiratory consideration for Legionnaires disease and chemicals, and any other recognized hazards for the task Job plans must be established for all pressure washing activities before work execution. At a minimum, this should include basic job steps, parameters, and safeguards. If a Job Hazard Analysis (JHA) is performed on a specific pressure washing job, then this JHA must be reviewed each time the job is performed. A copy of the JHA must be on the job site attached to the SWP issued for that job. Not all pressure washing jobs can be covered by a single JHA; therefore, each different job must have a JHA, if this is the method to be used for review of the job prior to starting work Barricading of the pump(s) and the job site hazards is required on every job and should be placed accordingly to restrict unauthorized personnel from entering the work area. Barricading should also include the end point of the

11 Procedure No.: MC Page: 11 of 17 operation. The barricade tape shall read Danger Pressure Washing. A tag on the barricade should identify the supervisor for the cleaning job. Permission to enter the barricaded work area should be granted only from the approval of the supervisor or employee performing the work. The barricaded area shall encompass all of the hoses in use at the pressure washing work area. When working above ground level, barricades will be required below Pressure washing equipment shall be grounded per site and or contract/contractor company requirements Whip checks are required at all hose to hose connections All component parts and fittings shall be checked for correct size and rating for the unit Pressure hoses shall not be bent or pinch as this may cause internal damage that is not easily identified during pre-job inspections. Do not use tools such as pliers, wrenches, vise grips, etc. directly on the hose portion, as these tools may cause internal damage All hose assemblies shall be inspected for the following criteria: Assemblies shall be free from external damage such as broken wires or excessive braids showing All end fittings and couplings are in good order and satisfy pressure rating for the unit operating pressure Only threaded hose connections are to be used at the pump connection All hoses shall be tested on a quarterly basis. This testing shall be documented and records made available to BASF when requested. Tags, bands, etc. shall be used to indicate hose inspection/testing dates Any electrical equipment in the immediate area of the pressure washing activity that presents a hazard to the operator or could damage equipment will be de-energized, shielded, or otherwise made safe Pressure washing on process piping or equipment that contains a hazardous energy source shall require a safe work permit Pressure washing wands shall not be pointed at personnel Pressure washing wand triggers assembly shall not be locked in position and if equipped with a locking mechanism, such a locking mechanism shall be removed or disabled The system shall be completely flushed with sufficient water to remove any contaminants before installing the nozzle.

12 Procedure No.: MC Page: 12 of Equipment shall not be left unattended when in operation nor under pressure Periodic, Before Use Inspection and Preventive Maintenance Hydroblasting companies shall have an equipment inspection program that ensures equipment is ready is ready for service before job identification or notification. Before job notification, the inspection of high pressure hoses and flex lances must include the visual inspection for hose deficiencies (bulges, cracks, etc.), integrity of the compressed fittings, outer cover, and no evidence of broken wire braids. If one or more broken wire braids exist the hose must be removed from service and discarded Once equipment is staged, all hose assemblies shall be inspected for leaks and/or damage All high pressure hoses with outer rubber or plastic covering construction and assemblies, including shotgun whip hoses/assemblies, must be quarterly tested to the working pressure (WP) of those hoses at a minimum. Hoses must have tags/bands, etc. to reflect the current testing period Documentation of hose tests must be recorded to indicate quarterly testing at a minimum. The hose test documentation should include the type (e.g., 10K, 20K, and/or 40K), size and identifying markings (e.g., serial number or special numbering/tagging/banding system) on the hoses to ensure testing of all hoses. This documentation shall be available for BASF McIntosh review when requested All pressure relief systems on pumps shall be inspected and tested, at a minimum, on a quarterly basis. This includes a visual inspection to verify the overall physical condition of the pressure relief systems. Visual evidence of the inspection frequency is required. Documentation of the inspections shall be maintained and shall be available to BASF McIntosh upon request Required Elements for Hydroblasting Companies Programs All hydroblasting companies shall have a training program. This training program shall include but is not limited to energy isolation of equipment, confined space entry, correct body positioning for tasks, using shotguns, flex lancing, rigid lancing, line moling, fall protection and installation of antiwithdrawal safety devices at a minimum. All hydroblasting personnel working at the BASF McIntosh site shall be familiar with and understand the Big 5 Permit requirements.
