b.
Ventilation exhaust shall be directed to a non-work area to avoid
exposing other people to potential toxic or dangerous fumes.
c.
Air removed from the work area by the ventilation system must be
replenished with fresh air to avoid oxygen starvation or a build-up of
fumes or gases. Only use air to provide ventilation. Any other combination
of gases may be explosive or toxic to people in the work area.
d.
Ventilation methods that remove gas and fumes from the welding
point before they reach the welder's face should be given preference.
4.
Avoid welding in a work area that has vapours from cleaning, degreasing or
any spraying operations. The heat and light from welding can react with the
vapour and form irritating or potentially toxic gases. Wait for the vapours to
disperse.
5.
Consult the manufacturer's Safety Data Sheets (SDS) for instructions and
precautions about metals, consumables, coatings, cleaners and
degreasers.
a.
Do not weld on coated metals such as galvanized, lead or cadmium
plated steel, unless the coating is removed from the weld area. The
coatings and any metals containing these elements can give off toxic
fumes during the welding process.
b.
Do not weld, cut or heat lead, zinc, cadmium, mercury, beryllium or
similar metals without seeking professional advice and inspection of
the welding area's ventilation. These metals produce extreme toxic
fumes, which can cause discomfort, illness and death.
c.
Do not weld or cut near chlorinated solvents or in areas that
chlorinates solvents can enter. The heat or ultraviolet light of the arc
can separate chlorinated hydrocarbons into a toxic gas (phosgene)
that can poison or suffocate the user or bystanders.
AIR TOOL PRECAUTIONS
1.
Extended exposure to air tool noise may cause hearing loss. Ear protection
gear can reduce or eliminate the noise level.
2.
Inspect the tool's air hose for cracks, fraying or other faults before each
use. Discontinue use if the air hose is damaged or hissing is heard from
the air hose or connectors, while operating the tool. Replace the
defective component/air hose.
