COMPRESSED GAS ASSOCIATION PAMPHLET P-1-1965 PDF

C ; or A gas or mixture of gases having, in a container, an absolute pressure exceeding psi at deg. C regardless of the pressure at 70 deg. C ; or A liquid having a vapor pressure exceeding 40 psi at deg. Compressed gases can be toxic, flammable, oxidizing, corrosive, or inert. In the event of a leak, inert gases can quickly displace air in a large area creating an oxygen-deficient atmosphere, toxic gases can create poison atmospheres, and flammable or reactive gases can result in fire and exploding cylinders.

Accidents occurring during the transportation, handling, use and storage of these containers can almost invariably be traced to failure to follow ICC requirements or to abuse or mishan- dling of the containers. General precautions are also included for tank car handling and reference is made to cargo tank handling.

It should not be assumed that every acceptable safety precaution is contained herein, or that abnormal or un- usual circumstances may not warrant or require further or additional procedure. However, by the issuance of this pamphlet the association and its members, jointly and severally, make no guarantee of results and assume no liability in connection with the information herein contained, or for the safety suggestions herein made.

The transportation of compressed gases by water comes under the jurisdiction of the United States Coast Guard. Transportation of compressed gases by air is regulated by the Federal Aviation Agency. In Canada, containers in which compressed gases are shipped by rail must comply with the specifications and regulations of the Board of Transport Commissioners for Canada BTC. Page 2 Compressed Gas Association, Inc. CGA P-1 — 2. For transportation of gases by other means, see regulations published by other governing agencies, such as U.

Coast Guard. Refer- ences to other publications giving additional handling precautions for specific gases are listed in Section 6. Page 3 3. Remove the leaking cylinder out of doors to a well ventilated location. If the gas is flammable or toxic, place an appropriate sign at the cylinder, warning against these hazards. Notify the gas supplier and follow his instructions as to the return of the cylinder. It is illegal to ship compressed gas in cylinders that have been exposed to fire.

Consult your supplier for advice un- der these circumstances. Cover label with Empty Label meeting ICC requirements, or if cylinder is provided with combination shipping and caution tag remove lower portion. A flame should never be permitted to come in contact with any part of a compressed gas cylinder. Many steels undergo decreased ductility at low temperatures. Page 4 Compressed Gas Association, Inc. CGA P-1 — 3. When the cylinders are used in con- junction with electric welding, precautions must be taken against accidentally grounding compressed gas cylin- ders and allowing them to be burned by electric welding arc.

Slings, ropes or chains should not be used unless provisions have been made on the cylinder for appropriate lifting attachments, such as lugs. A crane may be used when a safe cradle or platform is provided to hold the cylinders. It is safer to move cylinders even short distances by using a suitable truck. Page 5 3. Where practical, storage rooms should be fire-resistant. Storage in subsurface locations should be avoided.

Cylinders should not be stored at temperatures above F, nor near radiators or other sources of heat. Rusting will damage the cylinders and may cause the valve protective caps to stick. Do not store cylinders near elevators or gangways, or in locations where heavy moving objects may strike or fall on them. Where caps are provided for valve protection, such caps should be kept on cylinders in storage.

If ice or snow accumulate on a cylinder, thaw at room temperature, or with water at a temperature not exceeding F. Page 6 Compressed Gas Association, Inc. If cylinder content is not identified by marking, return cylinder to the supplier without using. Threads on regulator connections or other auxiliary equipment must be the same as those on cylinder valve outlet. Point the valve opening away from yourself and other persons.

Never use wrenches or tools except those provided or approved by the gas manufacturer. Avoid the use of a wrench on valves equipped with handwheels. Never hammer the valve wheel in attempting to open or close the valve.

For valves that are hard to open, or frozen because of corrosion, contact the supplier for instructions. Where hose is used, it should be kept in good condition. Page 7 3. Use soapy water. They should be segregated. Inside of buildings, stored oxygen and fuel gas cylinders should be separated by a minimum of 20 feet, or there should be a fire-resistive partition between the oxygen and fuel gas cylinders.

Bureau of Mines for the particular service desired Such equipment should be located convenient to the place of work, but kept out of the area most likely to be contaminated. Poison gases emitted from equipment in high concentration should be discharged into appropriate scrubbing equipment which will remove it from effluent streams.

These materials are maintained at extremely low temperatures, and cylinders must be kept upright to permit venting of vapor periodically to maintain safe internal pressures. Before a tank car can be charged with a compressed gas other than that for which com- modity use has been approved by the Tank Car Committee of the Association of American Railroads, approval must be obtained from this committee by the car owner or party authorized by the owner.

Page 9 4. In the event of a leak in the tank car or fittings which cannot be repaired by simple adjustments, telephone the supplier for instructions. Angle valves should be opened slowly to avoid closing of check valves in the eduction pipe. The use of a hammer on valve or cover plate to release a check valve should be avoided.

Operators should be pro- vided with proper personal protective equipment. Caution signs must be so placed on the track or car as to give necessary warning to persons approaching car from open end or ends of siding and must be left up until after car is unloaded and disconnected. The letters must be white on blue background. Page 10 Compressed Gas Association, Inc. CGAP-1 — 4. However, in cases where a cargo tank is handled by the user, he should consult the gas supplier for instructions on safe handling proce- dures.
