ARC WELDING SAFETY INSTRUCTIONS AND WARNINGS
Instruction 830001
2-2 May 8, 1996
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 con-
tact 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 rec-
ommended.
2. Wear proper body protection to protect skin.
CYLINDERS can explode if damaged.
Shielding gas cylinders contain gas under high pres-
sure. 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, mechan-
ical shocks, and arcs.
2. Install and secure cylinders in an upright position by chaining
them to a stationary support or equipment cylinder rack to pre-
vent 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, asso-
ciated equipment, and CGA publication P-1 listed in Safety Stan-
dards.
ENGINES can be hazardous.
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.
FUMES AND GASES can be hazardous
to your health.
Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.
1. Keep your head out of the fumes. Do not breath the fumes.
2. If inside, ventilate the area and/or use exhaust at the arc to re-
move welding fumes and gases.
3. If ventilation is poor, use an approved air-supplied respirator.
4. Read the Material Safety Data Sheets (MSDSs) and the manu-
facturer’s instruction for metals, consumables, coatings, and
cleaners.
5. Work in a confined space only if it is well ventilated, or while wear-
ing an air-supplied respirator. Shielding gases used for welding
can displace air causing injury or death. Be sure the breathing air
is safe.
6. Do not weld in locations near degreasing, cleaning, or spraying
operations. The heat and rays of the arc can react with vapors to
form highly toxic and irritating gases.
7. Do not weld on coated metals, such as galvanized, lead, or cad-
mium plated steel, unless the coating is removed from the weld
area, the area is well ventilated, and if necessary, while wearing
an air-supplied respirator. The coatings and any metals contain-
ing these elements can give off toxic fumes if welded.
