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.
