FUMES AND GASES CAN BE DANGEROUS
Welding may produce fumes and gases hazardous to health. Avoid
breathing these fumes and gases. When welding, keep your head out
of the fume. 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 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.
ARC RAYS CAN BURN.
Use a shield with the proper filter and cover plates to protect your eyes
from sparks and the rays of the arc when welding or observing open
arc welding.
Use suitable clothing made from durable flame-resistant material to
protect your skin and that of your helpers from the arc rays.
Protect other nearby personnel with suitable, non-flammable screening
and /or warn them not to watch the arc nor expose themselves to the
arc rays or to hot spatter or metal.
