protect your eyes and skin from arc rays and sparks when welding
or watching.
•
Use protective screens or barriers to protect other nearby
personnel with suitable, non-flammable screening and/or warn
them not to watch the arc nor expose themselves to the arc rays
or to hot spatter or material.
Fumes and
gases can be
dangerous
•
Welding may produce fumes and gases, breathing these fumes
and gases can be hazardous to your health.
•
When welding, keep your head out of the fume. If inside, ventilate
the area at the arc to keep fumes and gases away from the
breathing zone. If ventilation is not good, wear an approved
air-supplied respirator.
•
Work in a confined space only if it is well ventilated, or while
wearing an air-supplied respirator.
•
Welding fumes and gases can displace air and lower the oxygen
level causing injury or death. Always use enough ventilation,
especially in confined areas, to insure breathing air is safe.
Welding and
cutting
sparks can
cause fire or
explosion
.
•
When not welding, make 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.
