CYLINDER may explode if damaged.

5.a. Use only compressed gas cylinders containing the correct

shielding gas for the process used and properly operating reg-

ulators designed for the gas and pressure used. All hoses, fit-

tings, etc. should be suitable for the application and main- tained in good condition.

5.b. Always keep cylinders in an upright position securely chained to an undercarriage or fixed support.

5.c. Cylinders should be located:

Away from areas where they may be struck or subjected to physical damage.

A safe distance from arc welding or cutting operations and

any other source of heat, sparks, or flame.

5.d. Never allow the electrode, electrode holder or any other electrically “hot” parts to touch a cylinder.

5.e. Keep your head and face away from the cylinder valve outlet when opening the cylinder valve.

5.f. Valve protection caps should always be in place and hand tight except when the cylinder is in use or connected for use.

5.g. Read and follow the instructions on compressed gas cylinders, associated equipment, and CGA publication P-l, “Precautions for Safe Handling of Compressed Gases in Cylinders,”available from the Compressed Gas Association 1235 Jefferson Davis Highway, Arlington, VA 22202.
