Welding and cutting sparks can cause fire or explosion.
sure the electrode circuit is not touching the work or ground. Accidental contact can
cause sparks, explosion, overheating, or fire. Make sure the area is safe before doing
any welding.
Welding and cutting on closed containers, such as tanks, drums, or containers, can
cause them to blow up. Make sure proper steps have been taken.
When pressure gas is used at the work site, special precautions are required to
prevent hazardous situations.
Connect work cable to the work as close to the welding zone as practical to prevent
welding current from passing too long and creating fire hazards or overheat.
Wear oil-free protective garments such as leather gloves, heavy shirt, cuffless
trousers, high shoes, and a cap. Wear ear plugs when welding out of position or in
confined places. Always wear safety glasses with side shields when in a welding
area.
Be attention that welding sparks and hot materials from welding can easily go
through small cracks and openings to adjacent areas and start a fire. Remove fire
hazardous from the welding area, if not possible, cover them thoroughly. Do not weld
where flying sparks can strike flammable material and where the atmosphere may
contain flammable dust, gas, or liquid vapors (such as gasoline).
Protect yourself and others from flying sparks and hot metal. Remove any
combustibles from operator before perform any welding.
Keep a fire extinguisher readily available.
Empty containers, tanks, drums, or pipes which have combustibles before perform
welding.
Remove stick electrode from electrode holder or cut off welding wire at contact tip
when not in use.
Apply correct fuses or circuit breakers. Do not oversize or bypass them.
When not welding, make

pressure. If damaged, a cylinder can explode. Since gas cylinders are normally part
of the welding process, be sure to treat them carefully.
Cylinders should be located away from areas where they may be struck or subjected
to physical damage. Use proper equipment, procedures, and sufficient number of
persons to lift and move cylinders.
Always install cylinders in an upright position by securing to a stationary support or
cylinder rack to prevent falling over or tipping.
Keep a safe distance from arc welding or cutting operations and any other source of
heat, sparks, or flame.
No touching cylinder by welding electrode, electrode holder or any other electrically
“hot” parts. Do not drape welding cables or welding torches over a gas cylinder.
Use only correct compressed gas cylinders, regulators, hoses, and fittings designed
for the process used; maintain them and associated parts in good condition.
Use only compressed gas cylinders containing the correct shielding gas for the
properly operating regulators designed for the gas and pressure used. All hoses,
Pressure gas cylinders contain gas under high
