protecon. Welding on closed containers, such as tanks,
drums, or pipes, can cause them to blow up. Sparks can y
o from the welding arc. The ying sparks, hot work piece,
and hot equipment can cause res and burns. Accidental
contact of electrode to metal objects can cause sparks,
explosion, overheang, or re. Check and be sure the area
is safe before doing any welding.
WELDING can cause re or explosion.
Remove all ammables within 10m of the welding arc.
If this is not possible, ghtly cover them with approved
covers.
Do not weld where ying sparks can strike ammable
material.
Protect yourself and others from ying 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 re, and keep a re exnguisher nearby. Be
aware that welding on a ceiling, oor, bulkhead, or paron
can cause re on the hidden side.
Do not weld on closed containers such as tanks, drums, or
pipes, unless they are properly prepared according to local
regulaons
Connect work cable to the work as close to the welding
area as praccal to prevent welding current from travelling
along, possibly unknown paths and causing electric shock,
sparks, and re hazards.
Cut o welding wire at contact p when not in use.
Wear oil-free protecve garments such as leather gloves,
heavy shirt, cuess trousers, high shoes, and a cap. Remove
any combusbles, 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 ying metal. As welds cool they can throw o slag.
Wear approved safety glasses with side shields even under
your welding helmet.
BUILDUP OF GAS can injure or kill.
Shut o shielding gas supply when not in use. Always
venlate conned 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 aect pacemakers.
Pacemaker wearers keep away.
Wearers should consult their doctor before going near arc
welding, gouging, or spot welding operaons.
NOISE can damage hearing.
Noise from some processes or equipment can damage
hearing.
Wear approved ear protecon 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 ames,
sparks, and arcs. Install cylinders in an upright posion by
securing to a staonary support or cylinder rack to prevent
falling or pping. 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 ngs designed for the specic
applicaon; maintain them and associated parts in good
condion.
Turn face away from valve outlet when opening cylinder
valve.
Use the right equipment, correct procedures, and
sucient number of persons to li and move cylinders.
