FUMES AND GASES -- Fumes and
gases, can cause discomfort or harm,
particularly in confined spaces. Do
not breathe fumes and gases. Shield-
ing gases can cause asphyxiation.
Therefore:
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.
5. WARNING: This product, when used for welding or
cutting, produces fumes or gases which
contain chemicals known to the State of
California to cause birth defects and, in
some cases, cancer. (California Health &
Safety Code
§
25249.5 et seq.)
CYLINDER HANDLING -- Cylinders, if
mishandled, can rupture and violently
release gas. Sudden rupture of cylin-
der, 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 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
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.
ADDITIONAL SAFETY INFORMATION -- For
more information on safe practices for electric
arc welding and cutting equipment, ask your
supplier for a copy of "Precautions and Safe
Practices for Arc Welding, Cutting and Goug-
ing", Form 52-529.
