Such buildings or rooms shall have no open flames for heating or lighting and shall be well-ventilated. L Where a special wrench is required it shall be left in position on the stem of the valve while the cylinder is in so that the fuel-gas flow can be quickly turned off in case of. P Unless connected to a manifold, oxygen from a cylinder shall not be without first attaching an oxygen regulator to the cylinder valve. No one, except the owner of the cylinder or person authorized by him, shall refill a cylinder. A good guideline is to follow the cylinder valve material, if the cylinder valve is brass, brass or stainless regulators and fittings should be acceptable, if the cylinder valve is stainless steel, brass regulators and fittings should not be used.

The of liquid acetylene shall be prohibited. C When the gas holder is not located within a heated building, gas holder seals shall be protected against freezing. Within these types there are variations of thread type, size and direction as well as outside diameter. Valve-protection caps are designed to protect cylinder valves from damage. The fluid for oxygen manifolds shall be oil-free and not combustible. Unless specifically for higher ratings, carbide-feed generators shall be rated at 1 cubic foot 0. The or bend shall be so constructed that it will not be obstructed by rain, snow, ice, insects, or birds.

Standard for Compressed Gas Cylinder Valve Outlet and Inlet Connections

Drain valves shall be installed for this purpose having outlets normally closed with screw caps or plugs. This cap shall be to seal the outlet except when a hose, a regulator, or piping is attached. It shall terminate in a or bend located at least 12 feet 3. E Cylinders not having fixed hand shall have keys, handles, or nonadjustable wrenches on valve stems while these cylinders are in service. B When recharging generators the order of operations specified in the instructions supplied by the manufacturer shall be followed. I Fuel-gas shall never be 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.

If transported by , the motor shall be turned off during charging, cleaning, and generating periods. C Except when generators are prepared in accordance with of , sources of ignition shall be prohibited in outside generator houses or inside generator rooms. Contacts with third rails, trolley wires, etc. D Compressor or booster pumps shall be provided with pressure relief valves which will relieve pressure exceeding 15 psig 103 kPa gauge pressure to a safe outdoor location as provided in of , or by returning the gas to the inlet side or to the gas supply source. In order to prevent collapse of the gas bell or infiltration of air due to a vacuum caused by the compressor or booster pump or cooling of the gas, a compressor or booster cutoff shall be provided at a point 12 0. Pipe laid underground in earth shall be located below the frost line and protected against corrosion.

Rough handling, knocks, or falls are liable to damage the cylinder, valve or safety devices and cause leakage. For heating systems see of. A Calcium carbide not exceeding 600 pounds 272. C Valve-protection caps shall not be for lifting cylinders from one vertical position to another. C Compressors and booster pump equipment shall be located in well-ventilated areas away from open flames, or mechanical sparks, or other ignition sources. This standard is based on a coordinated plan for the inclusion of future connections as they are required on cylinders that are not permanently manifolded during transport and use.

This paragraph e 4 viii does not apply to machines. Rules and instructions covering the operation and maintenance of oxygen or fuel-gas supply equipment including generators, and oxygen or fuel-gas distribution piping systems shall be readily available. Oxygen piping may be placed in the same tunnel, trench or duct with fuel-gas pipelines, provided there is good natural or forced ventilation. For oxygen piping, only oil-free air, oil-free nitrogen, or oil-free carbon dioxide shall be used. Any practice such as the tapping of an electrode against a cylinder to strike an arc shall be prohibited.

B Wiring and electric equipment in compressor or booster pump rooms or enclosures shall conform to the provisions of of this part for Class I, Division 2 locations. C In the case of batch-type generators, when the charge of carbide is exhausted and before additional carbide is added, the generating chamber shall always be flushed out with water, renewing the water supply in accordance with the instruction card furnished by the manufacturer. Special buildings, rooms or compartments shall have no open flame for heating or lighting and shall be well ventilated. If of the socket type, they shall be brazed with silver-brazing alloy or similar high melting point not less than 800 °F 427 °C filler metal. When only a portion of a fuel-gas system is to be with oxygen, only that portion need comply with this paragraph e 3 i. H Safety devices shall not be tampered with. The outlet connections are designed to minimize the possibility of hazardous misconnections.

Oxygen manifolds shall be separated from fuel-gas cylinders or combustible materials especially oil or grease , a minimum distance of 20 feet 6. D Portable generators shall be protected against freezing. Where a noncontinuous connection is used, the supply line shall terminate at a point not less than 2 5 cm above the regularly provided opening for filling so that the water can be observed as it enters the generator. If low points are unavoidable, drip pots with drains closed with screw plugs or caps shall be installed at the low points. C Portable generators shall not be in rooms of total volume less than 35 times the total gas-generating capacity per charge of all generators in the room. The three functions of the protective equipment may be combined in one device or may be provided by separate devices. Equipment shall be installed and only in the service for which it is and as recommended by the manufacturer.
