Arc rays from the welding process produce intense

visible and invisible (ultraviolet and infrared) rays

that can burn eyes and skin. Sparks fly off from the

weld.

ARC RAYS can burn eyes and skin.

D

Wear an approved  welding helmet fitted with a proper shade of fil-

ter lenses to protect your face and eyes when welding or watching

(see ANSI Z49.1 and Z87.1 listed in Safety Standards).

D

Wear approved safety glasses with side shields under your

helmet.

D

Use protective screens or barriers to protect others from flash,

glare and sparks; warn others not to watch the arc.

D

Wear protective clothing made from durable, flame-resistant mate-

rial (leather, heavy cotton, or wool) and foot protection.

Welding on closed containers, such as tanks,

drums, or pipes, can cause them to blow up. Sparks

can fly off from the welding arc. The flying sparks, hot

workpiece, and hot equipment can cause fires and

burns. Accidental contact of electrode to metal objects can cause

sparks, explosion, overheating, or fire. Check and be sure the area is

safe before doing any welding.

WELDING can cause fire or explosion.

D

Remove all flammables within 35 ft (10.7 m) of the welding arc. If

this is not possible, tightly cover them with approved covers.

D

Do not weld where flying sparks can strike flammable material.

D

Protect yourself and others from flying sparks and hot metal.

D

Be alert that welding sparks and hot materials from welding can

easily go through small cracks and openings to adjacent areas.

D

Watch for fire, and keep a fire extinguisher nearby.

D

Be aware that welding on a ceiling, floor, bulkhead, or partition can

cause fire on the hidden side.

D

Do not weld on closed containers such as tanks, drums, or pipes,

unless they are properly prepared according to AWS F4.1 (see

Safety Standards).

D

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, sparks, and fire

hazards.

D

Do not use welder to thaw frozen pipes.

D

Remove stick electrode from holder or cut off welding wire at

contact tip when not in use.

D

Wear oil-free protective garments such as leather gloves, heavy

shirt, cuffless trousers, high shoes, and a cap.

D

Remove any combustibles, such as a butane lighter or matches,

from your person before doing any welding.

D

Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B

for hot work and have a fire watcher and extinguisher nearby.

FLYING METAL can injure eyes.

D

Welding, chipping, wire brushing, and grinding

cause sparks and flying metal. As welds cool,

they can throw off slag.

D

Wear approved safety glasses with side

shields even under your welding helmet.

BUILDUP OF GAS can injure or kill.

D

Shut off shielding gas supply when not in use.

D

Always ventilate confined spaces or use

approved air-supplied respirator.

HOT PARTS can cause severe burns.

D

Do not touch hot parts bare handed.

D

Allow cooling period before working on gun or

torch.

D

To handle hot parts, use proper tools and/or

wear heavy, insulated welding gloves and

clothing to prevent burns.

MAGNETIC FIELDS

 can affect pacemakers.

D

Pacemaker wearers keep away.

D

Wearers should consult their doctor before

going near arc welding, gouging, or spot

welding operations.

NOISE can damage hearing.

Noise from some processes or equipment can

damage hearing.

D

Wear approved ear protection if noise level is

high.

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.

CYLINDERS can explode if damaged.

D

Protect compressed gas cylinders from excessive heat, mechani-

cal shocks, physical damage, slag, open flames, sparks, and arcs.

D

Install cylinders in an upright position by securing to a stationary

support or cylinder rack to prevent falling or tipping.

D

Keep cylinders away from any welding or other electrical circuits.

D

Never drape a welding torch over a gas cylinder.

D

Never allow a welding electrode to touch any cylinder.

D

Never weld on a pressurized cylinder 

−

 explosion will result.

D

Use only correct shielding gas cylinders, regulators, hoses, and fit-

tings designed for the specific application; maintain them and

associated parts in good condition.

D

Turn face away from valve outlet when opening cylinder valve.

D

Keep protective cap in place over valve except when cylinder is in

use or connected for use.

D

Use the right equipment, correct procedures, and sufficient num-

ber of persons to lift and move cylinders.

D

Read and follow instructions on compressed gas cylinders,

associated equipment, and Compressed Gas Association (CGA)

publication P-1 listed in Safety Standards.
