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 a welding helmet fitted with a proper shade of filler to protect your face and eyes when welding or
watching (see Safety Standards).
 Wear approved safety glasses with side shields under your helmet.
 Use protective screens or barriers to protect others from flash and glare; warn others not to watch the arc.
 Wear protective clothing made from durable, flame-resistant material (leather and wool) and foot
protection.
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 work piece, and hot
equipment can cause fires and burns. Accidental contact of electrode to metal objects
can cause sparks, explosion, overheating, or lure. Check and be sure the area is safe
before doing any welding.
 Protect yourself and others from flying sparks and hot metal.
 Do not weld where flying sparks can strike flammable material.
 Remove all flammables within 35 ft (10.7 m) of the welding arc. If this is not possible, tightly cover them
with approved covers.
 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 weld on closed containers such as tanks, drums, or pipes, unless they are properly prepared
according to Safety Standards.
 Connect work cable to the work as close to the welding area as practical to prevent welding current from
travelling long, possibly unknown paths and causing electric shock and fire hazards.
 Do not use welder to thaw frozen pipes.
 Remove stick electrode from holder or cut off welding wire at contact tip when not in use.
 Wear oil-free protective garments such as leather gloves, heavy shirt, cuff less trousers, high shoes, and a
cap.
 Remove any combustibles, such as butane lighter or matches, from your person before doing any welding.
