SAFETY

to two welders because voltage between the two can be the total of the open
circuit voltage of both welders.
When working above the floor level, use a safety belt to protect yourself from a
fall should you get an electric shock!
FUMES AND GASES CAN BE 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. Use enough ventilation and/or exhaust at the arc to keep
fumes and gases away from the breathing zone. When welding with electrodes which
require special ventilation such as stainless or hard facing or on lead or cadmium
plated steel and other metals or coatings which produce highly toxic fumes, keep
exposure as low as possible and below the Threshold Limit Values using local
exhaust or mechanical ventilation. In confined spaces or in some circumstances,
outdoors, a respirator may be required. Additional precautions are also required
when welding on galvanized steel.
Do not weld in locations near chlorinated hydrocarbon vapors coming from
degreasing, cleaning or spraying operations. The heat and rays of the arc can react
with solvent vapors to form phosgene, a highly toxic gas, and other irritating
products.
Shielded gases used for arc welding can displace air and cause injury or death.
Always use enough ventilation, especially in confined areas, to insure breathing air
is safe.
Read and understand the manufacturer’s instructions for this equipment and the
consumables to be used, including the material safety data sheet and follow your
employer’s safety practices.
