5. Use only correct shielding gas cylinders,
regulators, hoses and fittings designed for
the specific application; maintain them
and associated parts in good condition.
6. Turn face away from valve outlet when
opening cylinder valve.
7. Keep protective cap in place over valve
except when cylinder is in use or con-
nected for use.
8. Read and follow instructions on com-
pressed gas cylinders, associated equip-
ment, and CGA publication P-1 listed in
Safety Standards.
F. Welding
Welding can cause fire or explosion.
Welding on closed containers, such as tanks,
drums, or pipes, can cause them to blow up.
Sparks can fly off from the welding arc. The
flying sparks, hot workpiece, and hot equipment
can cause fires and burns. Accidental contact of
electrode to metal objects can cause sparks, ex-
plosion, overheating, or fire. Check and be sure
the area is safe before doing any welding.
1. Protect yourself and others from flying
sparks and hot metal.
2. Do not weld where flying sparks can
strike flammable material.
3. Remove all flammables within 35 ft. (10.7
m) of the welding arc. If this is not pos-
sible, tightly cover them with approved
covers.
4. Be alert that welding sparks and hot mate-
rials from welding can easily go through
small cracks and openings to adjacent
areas.
5. Watch for fire, and keep a fire extin -
guisher nearby.
6. Do not weld on closed containers such
as tanks, drums, or pipes, unless they are
properly prepared according to AWSF4.1
(see safety Standards).
7. Connect work cable to the work as close
to the welding area as practical to prevent
welding current traveling long, possibly
unknown paths and causing electric
shock and fire hazards.
8. Wear oil-free protective garments such
as leather gloves, heavy shirt, cuffless
trousers, high shoes, and a cap.
G. Moving Parts
Moving parts, such as fans, rotors, and belts can
cut fingers and hands and catch loose clothing.
1. Keep all doors, panels, covers, and guards
closed and securely in place.
2. Have only qualified people remove
guards or covers for maintenance and
troubleshooting as necessary.
