This partition shall be without openings and shall be gastight. Oxygen cylinders in storage shall be separated from fuel-gas cylinders or combustible materials (especially oil or grease), a minimum distance of 20 feet or by a noncombustible barrier at least 5 feet high having a fireresistance rating of at least one-half hour.

11 Page 11 of 15 Sect: Liquid oxygen system with capacity more than 13,000 cubic feet shall not be used unless an engineered system meeting OHSA and NFPA standards for bulk oxygen storage has been approved by management Oxygen Cylinders Operating Procedures Compressed gas cylinders must be visually inspected prior to each use to determine that the cylinder is in safe condition for use. Cylinders, cylinder valves, couplings, regulators, hoses, and apparatus shall be kept free from oily or greasy substances. Oxygen cylinders or apparatus shall not be handled with oily hands or gloves. A jet of oxygen must never be permitted to strike an oily surface, greasy clothes, or enter a fuel, oil, or other storage tank. When transporting cylinders by a crane or derrick, a cradle, boat, or suitable platform shall be used. Slings or electric magnets shall not be used for this purpose. Cylinders not in use shall have the cap in place for cylinders designed to accept valve-protection caps. Cylinders shall not be dropped or struck or permitted to strike each other violently. Valve-protection caps shall not be used for lifting cylinders from one vertical position to another. Bars shall not be used under valves or valve-protection caps to pry cylinders loose when frozen to the ground or otherwise fixed; the use of warm (not boiling) water is recommended. Unless cylinders are secured on a special truck, regulators shall be removed and valve-protection caps, when provided for, shall be put in place before cylinders are moved. Cylinders not having fixed hand wheels shall have keys, handles, or nonadjustable wrenches on valve stems while these cylinders are in service. In multiple cylinder installations, only one key or handle is required for each manifold. Cylinder valves shall be closed before moving cylinders. Cylinder valves shall be closed when work is finished. Valves of empty cylinders shall be closed. Cylinders shall be kept far enough away from the actual welding or cutting operation so that sparks, hot slag, or flame will not reach them, or fireresistant shields shall be provided. Cylinders shall not be placed where they might become part of an electric circuit. Contacts with third rails, trolley wires, etc., shall be avoided. Cylinders shall be kept away from radiators, piping systems, layout tables, etc., that may be used for grounding electric circuits, such as for arc welding machines. Any practice such as the tapping of an electrode against a cylinder to strike an arc shall be prohibited. Cylinders shall never be used as rollers or supports, whether full or empty.

12 Page 12 of 15 Sect: The numbers and markings stamped into cylinders shall not be tampered with. No person, other than the gas supplier, shall attempt to mix gases in a cylinder. No one, except the owner of the cylinder or person authorized by him, shall refill a cylinder. No one shall tamper with safety devices in cylinders or valves. Cylinders shall not be dropped or otherwise roughly handled. Unless connected to a manifold, oxygen from a cylinder shall not be used without first attaching an oxygen regulator to the cylinder valve. Before connecting the regulator to the cylinder valve, the valve shall be opened slightly for an instant and then closed. Always stand to one side of the outlet when opening the cylinder valve. A hammer or wrench shall not be used to open cylinder valves. If valves cannot be opened by hand, the supplier shall be notified. Cylinder valves shall not be tampered with nor should any attempt be made to repair them. If trouble is experienced, the supplier should be sent a report promptly indicating the character of the trouble and the cylinder's serial number. Supplier's instructions as to its disposition shall be followed. Complete removal of the stem from a diaphragm-type cylinder valve shall be avoided Fuel-Gas Cylinders Operating Procedures Fuel-gas cylinders shall be placed with valve end up whenever they are in use. Liquefied gases shall be stored and shipped with the valve end up. Cylinders shall be handled carefully. Rough handling, knocks, or falls are liable to damage the cylinder, valve or safety devices and cause leakage. Before connecting a regulator to a cylinder valve, the valve shall be opened slightly and closed immediately. The valve shall be opened while standing to one side of the outlet; never in front of it. Never crack a fuel-gas cylinder valve near other welding work or near sparks, flame, or other possible sources of ignition. Before a regulator is removed from a cylinder valve, the cylinder valve shall be closed, and the gas released from the regulator. Nothing shall be placed on top of an acetylene cylinder when in use which may damage the safety device or interfere with the quick closing of the valve. If cylinders are found to have leaky valves or fittings which cannot be stopped by closing of the valve, the cylinders shall be taken outdoors away from sources of ignition and slowly emptied. A warning should be placed near cylinders having leaking fuse plugs or other leaking safety devices not to approach them with a lighted cigarette or other source of ignition. Such cylinders should be plainly tagged; the

13 Page 13 of 15 Sect: supplier should be promptly notified, and their instructions followed as to their return. Safety devices shall not be tampered with. Fuel-gas shall never be used from cylinders through torches or other devices equipped with shutoff valves without reducing the pressure through a suitable regulator attached to the cylinder valve or manifold. The cylinder valve shall always be opened slowly. An acetylene cylinder valve shall not be opened more than one and one-half turns of the spindle, and preferably no more than three-fourths of a turn. Where a special wrench is required, it shall be left in position on the stem of the valve while the cylinder is in use so that the fuel-gas flow can be quickly turned off in case of emergency. In the case of manifold or coupled cylinders, at least one such wrench shall always be available for immediate use. 9.0 Arc-Welding & Cutting 9.1 General Requirements Trained & Qualified - Employees performing arc-welding and cutting operations shall be trained and qualified in the proper and safe operation of such equipment.
