HOT PARTS can burn.

� Do not touch hot parts bare handed.

� Allow cooling period before working on equipment.

� To handle hot parts, use proper tools and/or wear

heavy, insulated welding gloves and clothing to

prevent burns.

FLYING METAL OR DIRT can injure

eyes.

� Welding, chipping, wire brushing, and grinding

cause sparks and flying metal. As welds cool, they

can throw off slag.

� Wear approved safety glasses with side shields even under your

welding helmet.

FUMES AND GASES can be

hazardous.

Welding produces fumes and gases. Breathing

these fumes and gases can be hazardous to your

health.

� Keep your head out of the fumes. Do not breathe the fumes.

� Ventilate the work area and/or use local forced ventilation at the

arc to remove welding fumes and gases. The recommended way

to determine adequate ventilation is to sample for the composition

and quantity of fumes and gases to which personnel are exposed.

� If ventilation is poor, wear an approved air-supplied respirator.

� Read and understand the Safety Data Sheets (SDSs) and the

manufacturer's instructions for adhesives, coatings, cleaners, con-

sumables, coolants, degreasers, fluxes, and metals.

� Work in a confined space only if it is well ventilated, or while wear-

ing an air-supplied respirator. Always have a trained watchperson

nearby. Welding fumes and gases can displace air and lower the

oxygen level causing injury or death. Be sure the breathing air is

safe.

� 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.

� Do not weld on coated metals, such as galvanized, lead, or cadmi-

um plated steel, unless the coating is removed from the weld area,

the area is well ventilated, and while wearing an air-supplied respi-

rator. The coatings and any metals containing these elements can

give off toxic fumes if welded.

BUILDUP OF GAS can injure or kill.

� Shut off compressed gas supply when not in use.

� Always ventilate confined spaces or use approved

air-supplied respirator.

ARC RAYS can burn eyes and skin.

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.

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

ter lenses to protect your face and eyes from arc rays and sparks

when welding or watching (see ANSI Z49.1 and Z87.1 listed in

Safety Standards).

� Wear approved safety glasses with side shields under your

helmet.

� Use protective screens or barriers to protect others from flash,

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

� Wear body protection made from leather or flame-resistant cloth-

ing (FRC). Body protection includes oil-free clothing such as leath-

er gloves, heavy shirt, cuffless trousers, high shoes, and a cap.

WELDING can cause fire or

explosion.

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, ex-

plosion, overheating, or fire. Check and be sure the area is safe be-

fore doing any welding.

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

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

� Do not weld where flying sparks can strike flammable material.

� Protect yourself and others from flying sparks and hot metal.

� Be alert that welding sparks and hot materials from welding can

easily go through small cracks and openings to adjacent areas.

� Watch for fire, and keep a fire extinguisher nearby.

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

cause fire on the hidden side.

� Do not cut or weld on tire rims or wheels. Tires can explode if

heated. Repaired rims and wheels can fail. See OSHA 29 CFR

1910.177 listed in Safety Standards.

� Do not weld on containers that have held combustibles, or on

closed containers such as tanks, drums, or pipes unless they are

properly prepared according to AWS F4.1 (see Safety Standards).

� Do not weld where the atmosphere can contain flammable dust,

gas, or liquid vapors (such as gasoline).

� 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.

� Do not use welder to thaw frozen pipes.

� Remove stick electrode from holder or cut off welding wire at con-

tact tip when not in use.

� Wear body protection made from leather or flame-resistant cloth-

ing (FRC). Body protection includes oil-free clothing such as leath-

er gloves, heavy shirt, cuffless trousers, high shoes, and a cap.

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

from your person before doing any welding.

� After completion of work, inspect area to ensure it is free of sparks,

glowing embers, and flames.

� Use only correct fuses or circuit breakers. Do not oversize or by-

pass them.

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

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

� Read and understand the Safety Data Sheets (SDSs) and the

manufacturer's instructions for adhesives, coatings, cleaners, con-

sumables, coolants, degreasers, fluxes, and metals.

NOISE can damage hearing.

Noise from some processes or equipment can

damage hearing.

� Wear approved ear protection if noise level is high.

ELECTRIC AND MAGNETIC FIELDS

(EMF) can affect Implanted Medical

Devices.

� Wearers of Pacemakers and other Implanted Med-

ical Devices should keep away.

� Implanted Medical Device wearers should consult their doctor and

the device manufacturer before going near arc welding, spot weld-

ing, gouging, plasma arc cutting, or induction heating operations.
