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
welding 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 stationary 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 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 connected for use.
8. Read and follow instructions on compressed gas cylinders,
associated equipment, and CGA publication P-1 listed in Safety
Standards.
