If ventilation is poor, use an approved respirator.
Do not weld near degreasing, cleaning or spraying booths. The heat and rays
from the arc can react with the gases from those processes to form toxic
fumes.
Do not weld on coated metals, such as galvanized, lead or cadmium plated
steel, unless the coating is removed. The coatings can give off toxic fumes if
welded.
Arc rays from the welding process produce intense rays that can burn skin and
eyes.
Wear a welding helmet fitted with correct shade of filter lens when welding in
order to protect eyes and face.
Use protective screens or barriers to protect passer-bys, warn others not to
watch the arc.
Wear protective clothing made from durable and flame-resistant material as
well as foot protection.
Protect exposed skin on hands with leather gloves.
Welding processes produce molten metal, sparks and hot work surfaces. These can
cause fire or explosion if precautionary measures are not followed. Welding on
closed containers can them to explode. Check and make sure the work area is safe
before doing any welding.
Remove any combustible material from the work area.
Remove or make safe all combustible materials for a radius of 10m around
the work area. If this is not possible then cover materials with approved
flame-resistant covers.
Do not weld where sparks can strike combustible material.
Do not weld on a container that has held an unknown substance or a
combustible material whose contents, when heated, can produce flammable
or explosive fumes.
Do not weld on a workpiece covered by an unknown substance or whose
coating can produce flammable, toxic, or reactive fumes when heated.
Do not use welder to thaw frozen pipes.
Do not weld on closed containers such as drums unless they are correctly
prepared.
Always keep a fire extinguisher close by.
