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 work piece,
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.
Remove all flammables within 10m 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 weld on closed containers such as tanks, drums, or
pipes, unless they are properly prepared according to local
regulations
Connect work cable to the work as close to the welding
area as practical to prevent welding current from travelling
along, possibly unknown paths and causing electric shock,
sparks, and fire hazards.
Cut off welding wire at contact tip when not in use.
Wear oil-free protective garments such as leather 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.
FLYING METAL 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.
BUILDUP OF GAS can injure or kill.
Shut off shielding gas supply when not in use. Always
ventilate confined spaces or use approved air-supplied
respirator.
HOT PARTS can cause severe burns.
Do not touch hot parts with bare handed.
Allow cooling period before working on gun or torch.
To handle hot parts, use proper tools and/or wear heavy,
insulated welding gloves and clothing to prevent burns.
MAGNETIC FIELDS can affect pacemakers.
Pacemaker wearers keep away.
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.
Wear approved ear protection if noise level is high.
Shielding gas cylinders contain gas under high pressure.
CYLINDERS can explode if damaged.
Protect compressed gas cylinders from excessive heat,
mechanical shocks, physical damage, slag, open flames,
sparks, and arcs. Install cylinders in an upright position by
securing to a stationary support or cylinder rack to prevent
falling or tipping. Keep cylinders away from any welding or
other electrical circuits. Never drape a welding torch over a
gas cylinder. Never allow a welding electrode to touch any
cylinder. Never weld on
a pressurized cylinder - explosion
will result. Use only correct shielding gas cylinders,
regulators, hoses, and fittings designed for the specific
application; maintain them and associated parts in good
condition.
Turn face away from valve outlet when opening cylinder
valve.
Use the right equipment, correct procedures, and
sufficient number of persons to lift and move cylinders.
