WElDING can cause fire or explosion.
Sparks and spatter fly off from the welding arc. The flying sparks
and hot metal, weld spatter, hot work piece, and hot equipment
can cause fires and burns. Accidental contact of electrode or weld-
ing wire to metal objects can cause sparks, over heating, or fire.
1. Protect yourself and others from flying sparks and hot metal.
2. Do not weld where flying sparks can strike flammable material. Remove all
flammables within 35ft (10.7 m) of the welding arc. If this is not possible,
tightly cover them with approved covers.
3. Be alert that welding sparks and hot materials from welding can easily go
through small cracks and openings to adjacent areas.
4. Watch for fire, and keep a fire extinguisher nearby.
5. Be aware that welding on a ceiling, floor, bulkhead, or partition can cause fire
on the hidden side.
6. Do not weld on closed containers such as tanks or drums.
7. Connect work cable to the work as close to the welding area as practical to
prevent welding current from travelling long, possibly unknown paths and
causing electric shock and fire hazards.
8. Do not use welder to thaw frozen pipes.
9. Remove stick electrode from holder or cut off welding wire at contact tip when
not in use.
Flying sparks and hot metal can cause
Injury.
Chipping and grinding cause flying metal. As welds cool, they
can throw off slag.
1. Wear approved face shield or safety goggles. Side shields recommended.
2. Wear proper body protection to protect skin.
CYlINDERS can explode if damaged.
Shielding gas cylinders contain gas under high pressure. If damaged,
a cylinder can explode. Since gas cylinders are normally part of the
welding process, be sure to treat them carefuIIy.
1. Protect compressed gas cylinders from excessive heat, mechanical shocks,
and arcs.
2. Install and secure cylinders in an upright position by chaining them to a station-
ary support or equipment cylinder rack to prevent falling or tipping.
3. Keep cylinders away from any welding or other electrical circuits.
4. Never allow a welding electrode to touch any cylinder.
5. Use only correct shielding gas cylinders, regulators, hoses and fittings designed
for the specific application; maintain them and associated parts in good condi-
tion.
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 compressed gas cylinders, associated equip-
ment, and CGA publication P-1 listed in Safety Standards.
