FUMES AND GASES -- Fumes and gases,
can cause discomfort or harm, particularly
in confined spaces. Do not breathe fumes
and gases. Shielding 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 mechani-
cal 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 hydrocarbon
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.
. Refer to ANSI/ASC Standard Z9.1 (see listing below) for
specific ventilation recommendations.
5. WARNING: This product, when used for welding or cut-
ting, 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 mis-
handled, 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 regula-
tor 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 pro-
tection cap in place if regulator is not connected. Secure and
move cylinders by using suitable hand trucks. Avoid rough
handling of cylinders.
. Locate cylinders away from heat, sparks, and flames. Never
strike an arc on a cylinder.
. For additional information, refer to CGA Standard P-1, “Precau-
tions for Safe Handling of Compressed Gases in Cylinders”,
which is available from Compressed Gas Association, 123
Jefferson Davis Highway, Arlington, VA 22202.
EQUIPMENT MAINTENANCE -- Faulty or improperly main-
tained 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.
. 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.
. 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.
