Arc rays: harmful to people’s eyes and skin.
Arc rays from the welding process produce intense visible and invisible ultraviolet and infrared rays that
can burn eyes and skin.
• Always wear a welding helmet with correct shade of filter lens and suitable protective clothing
including welding gloves whilst the welding operation is performed.
• Measures should be taken to protect people in or near the surrounding working area.
Use protective screens or barriers to protect others from flash,glare and sparks; warn others not to
watch the arc.
Welding can cause fire explosive,
Fire hazard.
Welding on closed containers, such as tanks,drums, or pipes, can cause them to explode. Flying sparks
from the welding arc, 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.
• The welding sparks & spatter may cause fire, therefore remove any flammable materials well away
from the working area. Cover flammable materials and containers with approved covers if unable to
be moved from the welding area.
• Do not weld on closed containers such as tanks, drums, or pipes, unless they are properly prepared
according to the required Safety Standards to insure that flammable or toxic vapors and substances are
totally removed, these can cause an explosion even though the vessel has been “cleaned”.
Vent hollow castings or containers before heating, cutting or welding. They may explode.
• Do not weld where the atmosphere may contain flammable dust, gas, or liquid vapours (such as petrol)
• Have a fire extinguisher nearby and know how to use it. Be alert that welding sparks and hot materials
from welding can easily go through small cracks and openings to adjacent areas. Be aware that welding
on a ceiling, floor, bulkhead, or partition can cause fire on the hidden side.
FUMES and gases can be hazardous.
Fumes and gases are dangerous. Smoke and gas generated whilst welding or cutting can be harmful
to people’s health. Welding produces fumes and gases. Breathing these fumes and gases can be
hazardous to your health.
• Do not breathe the smoke and gas generated whilst welding or cutting, keep your head out of the
fumes
• Keep the working area well ventilated, use fume extraction or ventilation to remove welding fumes and gases.
• In confined or heavy fume environments always wear an approved air-supplied respirator.
Welding fumes and gases can displace air and lower the oxygen level causing injury or death. Be sure the
breathing air is safe.
• Do not weld in locations near de-greasing, cleaning, or spraying operations. The heat and rays of the arc
can react with vapours to form highly toxic and irritating gases.
• Materials such as galvanized, lead, or cadmium plated steel, contain elements that can give off toxic
fumes when welded. Do not weld these materials unless the area is very well ventilated, and or wearing
an air supplied respirator.
