from the weld area, the area is well ventilated, and if
necessary, while wearing an air-supplied respirator. The
coatings and any metals containing these elements can
give off toxic fumes if welded.
WELDING can cause fire or explosion.
Sparks and spatter fly off from the welding arc.
The flying sparks and hot metal, weld spatter, hot
workpiece, and hot equipment can cause fires
and burns. Accidental contact of electrode or
welding wire to metal objects can cause sparks,
overheating, or fire.
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 possible, tightly cover them
with approved covers.
4. Be alert that welding sparks and hot materials from
welding can easily go through small cracks and openings
to adjacent areas.
5. Watch for fire, and keep a fire extinguisher nearby.
6. Be aware that welding on a ceiling, floor, bulkhead, or
partition can cause fire on the hidden side.
7. Do not weld on closed containers such as tanks or drums.
8. Connect work cable to the work as close to the welding
area as practical to prevent welding current from traveling
long, possibly unknown paths and causing electric shock
and fire hazards.
9. Do not use welder to thaw frozen pipes.
10. 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.

WARNING
WARNING
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 carefully.
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.
Engines can be dangerous.
ENGINE EXHAUST GASES can kill.
Engines produce harmful exhaust gases.
1. Use equipment outside in open, well-ventilated areas.
2. If used in a closed area, vent engine exhaust outside and
away from any building air intakes.
ENGINE FUEL can cause fire or explosion.
Engine fuel is highly flammable.
1. Stop engine before checking or adding fuel.
