FUMES AND GASES
Welding may produce hazardous fumes and gas during the
welding process. A well ventilated work area can normally remove
the fumes and gases, but sometimes the welding produces fumes
and gases that are hazardous to your health.
Stop welding if your eyes, nose or throat become irritated. This
indicates the ventilation is not adequate to remove the fumes.
Do not resume welding until the ventilation is improved and the
discomfort ceases.
1. Only work in a confined space if the area is well ventilated
or while wearing an air-supplied respirator. Always have a
trained watchperson nearby.
2. Avoid positions that allow welding fumes to reach your face.
3. Ventilate the work area to remove welding fumes and
gases. The fumes and gases should be drawn away from
the user. Welding fumes and gases can displace air and
lower the oxygen level causing injury or death. Be sure the
breathing air is safe.
3.1 If ventilation in the work area is poor, use an approved
air-supplied respirator. All the people in the work area
must also have air-supplied respirators.
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 Material Safety Data Sheets
(MSDS) for instructions and precautions about metals,
consumables, coatings, cleaners and degreasers.
5.1 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.
