3.
Use protective screens or barriers to protect
others from flash and glare; warn others not to
watch the arc.
4.
Wear protective clothing made from durable,
flame-resistant material (wool and leather)
and foot safety protection.
5.
Never wear contact lenses while welding.
Noise Can Damage Hearing
CAUTION!
Noise from some processes can damage
hearing. Use AS/NZS compliant ear plugs or ear
muffs if the noise level is high.
Work Environment Safety
DANGER!
Remove any combustible material from the
work area.
1.
When possible, move the work to a location well
away from combustible materials. If relocation
is not possible, protect the combustibles with
a cover made of fire resistant material.
2.
Remove or make safe all combustible materials
for a radius of 10 metres around the work area.
Use a fire resistant material to cover or block
all doorways, windows, cracks, and other
openings.
3.
Enclose the work area with portable fire
resistant screens. Protect combustible walls,
ceilings, floors, etc., from sparks and heat with
fire resistant covers.
4.
If working on a metal wall, ceiling, etc., prevent
ignition of combustibles on the other side by
moving the combustibles to a safe location.
If relocation of combustibles is not possible,
designate someone to serve as a fire watch,
equipped with a fire extinguisher, during the
welding process and well after the welding is
completed.
5.
Do not weld or cut on materials having a
combustible coating or combustible internal
structure, as in walls or ceilings, without an
approved method for eliminating the hazard.
6.
After welding, make a thorough examination
for evidence of fire. Be aware that visible
smoke or flame may not be present for some
time after the fire has started. Do not weld or
cut in atmospheres containing dangerously
reactive or flammable gases, vapours, liquids,
and dust. Provide adequate ventilation in work
areas to prevent accumulation of flammable
gases, vapours, and dust.
7.
Do not apply heat to a container that has
held an unknown substance or a combustible
material whose contents, when heated, can
produce flammable or explosive vapours.
Clean and purge containers before applying
heat. Vent closed containers, including
castings, before preheating, welding, or
cutting.
Electricity Can Kill
DANGER!
Touching live electrical parts can cause fatal
shocks or severe burns. The electrode and work
circuit is electrically live whenever the output is
on.
The input power circuit and machine internal
circuits are also live when power is on. In semi-
automatic or automatic wire welding, the wire,
wire reel, drive roll housing, and all metal parts
touching the welding wire are electrically live.
Incorrectly installed or improperly grounded
equipment is a hazard.
1.
Do not touch live electrical parts.
2.
Wear dry, hole-free insulating gloves and body
protection.
3.
Insulate yourself from the work and the
ground using dry insulating mats or covers.
4.
Disconnect input power before installing or
servicing this equipment. Lock input power,
disconnect switch open, or remove line fuses
so power cannot be turned on accidentally.
5.
Properly install and ground this equipment
according to national, state, and local codes.
6.
Turn off all equipment when not in use.
Disconnect power to equipment if it will be
left unattended or out of service.
7.
Use fully insulated electrode holders. Never dip
the holder in water to cool it or lay it down on
the ground or the work surface. Do not touch
holders connected to two welding machines
at the same time or touch other people with
the holder or electrode.
8.
Do not use worn, damaged, undersized, or
poorly spliced cables.
9.
Do not wrap cables around your body.
10. Connect work piece to a good electrical
ground.
