1 of 7 1.0 PURPOSE To provide a system of handling and storing compressed gas and fuel gas cylinders. This instruction details the materials and methods used to handle and store cylinders. All contractors performing work on Corporation property shall be instructed to follow the provisions of this instruction. 2.0 REFERENCE Plant Engineering and Environmental Planning Office Procedure No. 1-102 Federal and State Occupational Safety and Health Acts MTI SMI - 116, "Certification of Arc and Gas Cutters and Welders" MTI SMI - 118, " Use of Oxygen - Fuel Gas Equipment" 3.0 FUNCTIONS AFFECTED Manufacturing Engineering Facilities Engineering Production Control Employee Safety Security and Fire Prevention Services Industrial Hygiene 4.0 OPERATION AFFECTED Chrysler Corporation and Subsidiaries 5.0 INFORMATION AND INSTRUCTIONS 5.1 Handling 5.1.1 Cylinders may be moved for short distances by tipping and rolling them on the bottom edge, but shall not be bumped or dropped. Nor shall cylinders be dragged, rolled horizontally or slid. Rough handling may cause:
2 of 7 A. The cylinder valve to break. This could bring about an explosion or a violent movement of the cylinder. B. Cylinder leaks or ruptures. Escaping gas may cause a fire, explosion or severe injuries. 5.1.2 Cylinders shall always be transported in a firmly secured vertical position. Exhibit A shows a single cylinder truck. Exhibit B shows a fork truck rack suitable for moving several cylinders. Welding cart, NPWW-100, may be used for transporting two cylinders. 5.1.3 Cylinders in Emission Test Areas are generally handled in Multiple Cylinder Wheeled Specialty Gas Service Carts. Most commonly used are the six or eight cylinder capacity gas service carts referred to as the Six Pak or 8 Pak carts. Exhibit C illustrates the Six Pak Cart. 5.1.4 Specially designed powered vehicles may also be used for transporting cylinders in an upright contained position. 5.1.5 Cylinders may be lifted by cranes with a properly designed rack or cradle, but shall not be lifted by a lifting magnet or a rope, chain, or wire rope sling. 5.1.6 All Cylinders, full or empty, shall be handled with caution. 5.1.7 Valve-protection caps shall not be used for lifting cylinders from one position to another. 5.2 Storage 5.2.1 Empty cylinders are marked "EMPTY" or "MT", removed immediately from the working area and stored in an area separated from full cylinders. 5.2.2 Defective and/or leaking cylinders shall be moved to an isolated area outdoors, away from sources of ignition. 5.2.3 Cylinders containing in excess or 2000 cubic feet of gas shall be stored in a well-ventilated separated room or area. 5.2.4 Cylinders shall be stored and firmly supported in an upright position. Valves shall be closed and cylinders shall be capped. 5.2.5 Oxygen cylinders in storage shall be separated from fuel-gas cylinders a minimum distance of twenty
3 of 7 feet (20') or by a non-combustible barrier at least five feet (5') high having a fire-resistance rating of at least one-half (1/2) hour. 5.2.6 Cylinders shall be stored in dry areas, protected from the weather and sudden temperature changes. Cylinders shall not be stored near furnaces, radiators, in direct sunlight, etc. Heat will increase the pressure in the cylinder. 5.2.7 Storage areas shall be clean and free from oils, greases, and other flammable materials. 5.2.8 Storage areas inside buildings shall be protected by sprinkler systems whenever feasible. 5.2.9 Storage areas for cylinders shall be on a level, fireproof floor and shall be well ventilated to prevent the accumulation of gases. 5.2.10 Sources of ignition in cylinder storage areas shall not be permitted. Electrical wiring shall be in conduit. Electric lights shall be enclosed to prevent ignition of gases, and covered by guards to prevent breakage. Electric switches shall be located outside the storage areas. Smoking shall not be permitted. 5.2.11 Only cylinders conforming to O.S.H.A. specifications shall be allowed in Chrysler facilities. 5.2.12 Cylinders shall not be stored in a location where they may become damaged or knocked over by passing or falling objects. 5.2.13 Where a cylinder is designed to accept a valve protection cap, caps shall be kept in place except when the cylinder is in use or is connected for use. 5.2.14 All employees assigned to the handling of cylinders under pressure shall be adequately trained prior to assignment. 6.0 EXHIBITS Exhibit A - Single Cylinder Transport Truck Exhibit B - Multiple Cylinder Fork Truck Rack Exhibit C - Multiple Cylinder Wheeled Specialty Gas Service Cart
