1. Always provide adequate ventilation in the work area by

natural or mechanical means. Do not weld, cut, or gouge
on materials such as galvanized steel, stainless steel,
copper, zinc, lead, beryllium, or cadmium unless positive
mechanical ventilation is provided. Do not breathe fumes
from these materials.

2. Do not operate near degreasing and spraying operations.

The heat or arc rays can react with chlorinated hydrocar-
bon  vapors to form phosgene, a highly toxic gas, and
other irritant gases.

3. If you develop momentary eye, nose, or throat irritation

while operating, this is an indication that ventilation is not
adequate. Stop work and take necessary steps to improve
ventilation in the work area. Do not continue to operate if
physical discomfort persists.

4. Refer to ANSI/ASC Standard Z49.1 (see listing below) for

specific ventilation recommendations.

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 com-
pressed 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 connected.
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 As-
sociation, 1235 Jefferson Davis Highway, Arlington, VA
22202.

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.
