cYliNDer haNDliNg -- cylinders,
if mishandled, can rupture and vio-
lently release gas. sudden rupture
of cylinder, valve, or relief device can
injure or kill. therefore:
1. Use the proper gas for the process and use the
proper pressure reducing regulator designed to
operate from the compressed gas cylinder. Do not
use adaptors. Maintain hoses and fittings in good
condition. Follow manufacturer's operating instruc-
tions for mounting regulator to a compressed gas
cylinder.
2. Always secure cylinders in an upright position by
chain or strap to suitable hand trucks, undercar-
riages, benches, walls, post, or racks. Never secure
cylinders to work tables or fixtures where they may
become part of an electrical circuit.
3. When not in use, keep cylinder valves closed. Have
valve protection cap in place if regulator is not con-
nected. Secure and move cylinders by using suitable
hand trucks. Avoid rough handling of cylinders.
4. Locate cylinders away from heat, sparks, and flames.
Never strike an arc on a cylinder.
5. For additional information, refer to CGA Standard P-1,
"Precautions for Safe Handling of Compressed Gases
in Cylinders", which is available from Compressed
Gas Association, 1235 Jefferson Davis Highway,
Arlington, VA 22202.
eQuipmeNt maiNteNaNce -- Faulty or
improperly maintained equipment can
cause injury or death. therefore:
1. Always have qualified personnel perform the instal-
lation, troubleshooting, and maintenance work.
Do not perform any electrical work unless you are
qualified to perform such work.
2. Before performing any maintenance work inside a
power source, disconnect the power source from
the incoming electrical power.
3. Maintain cables, grounding wire, connections, power
cord, and power supply in safe working order. Do
not operate any equipment in faulty condition.
4. Do not abuse any equipment or accessories. Keep
equipment away from heat sources such as furnaces,
wet conditions such as water puddles, oil or grease,
corrosive atmospheres and inclement weather.
5. Keep all safety devices and cabinet covers in position
and in good repair.
6. Use equipment only for its intended purpose. Do
not modify it in any manner.
