2. ARC WELDING SAFETY PRECAUTIONS (continued)
ARC RAYS can burn eyes and skin: FLYING SPARKS AND HOT METAL can
cause injury. NOISE can damage hearing.
Arc rays from the welding process produce intense heat and strong ultraviolet rays that can
burn eyes and skin.
Noise from some arc welding can damage hearing.
1.
Wear face shield with a proper shade of filter (See ANSI Z 49.1 listed in PRINCIPAL
SAFETY STANDARDS) to protect your face and eyes when welding or watching a welder
work.
2.
Wear approved face shield or safety goggles. Side shields recommended.
3.
Use protective screens or barriers to protect others from flash and glare: warn others not
to look at the arc.
4.
Wear protective clothing made from durable, flame-resistant material (wool and leather)
and foot protection.
5.
Use approved earplugs or earmuffs if noise level is high.
Chipping and grinding can cause flying metal. As welds cool, they can throw off slag.
6.
Wear proper body protection to protect skin.
WELDING can cause fire and explosion.
Sparks and spatter fly off from the welding arc. The flying sparks,hot metal, spatter, hot base
metal and hot equipment can cause fire and explosion. Accidental contact of electrode or
welding wire to metal object can cause sparks, overheating, or fire.
Leaving piled-up dust in the welding machine may cause an insulation deterioration and result
in electrical shock and fire.
1.
Protect yourself and others from flying sparks and hot metals.
2.
Do not weld where flying sparks can strike flammable material.
3.
Remove all flammables within 10m (33ft) of the welding arc. If this is not possible, tightly,
cover them with approved covers.
4.
Be alert that welding sparks and hot metals from welding can easily pass through cracks
and openings into 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 ignite a hidden fire.
7.
Do not weld on closed containers such as tanks or drums.
8.
Connect power cable for base metal as close to the welding area as possible to prevent the
welding current from traveling along unknown paths and causing electric shock and fire
hazards.
9.
Remove stick electrode from holder or cut off welding wire at contact tip when not in use.
10. Do not use the welding power source for anything other than arc welding.
11. Wear oil-free protective garments such as leather gloves, a heavy shirt, cuffless trousers,
boots, and a cap.
12. A loose cable connection can cause sparks and excessive heating.
13. Tighten all cable connections.
14. When there is an electrical connection between a work piece and the frame of wire feeder or
the wire reel stand, arc may be generated and cause damage by a fire if the wire contacts
the frame or the work piece.
15. Remove dust by blowing moisture-free compressed air on each part periodically.
