SAFETY INSTRUCTIONS
1-3
CYLINDER HANDLING -- Cylinders, if mishandled, can rupture and violently 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 instructions for mounting regulator to a compressed gas cylinder.
2. Always secure cylinders in an upright position by chain or strap to suitable hand trucks, undercarriages,
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 installation, 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.
