SAFETY

___
ARC RAYS can burn.
3.a. Use a shield with the proper filter and cover plates to protect your eyes from sparks and
the rays of the arc welding or observing open arc welding.
3.b. Use suitable clothing made from durable flame-resistant material to protect your skin and
that of your helpers from the arc rays.
3.c. 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.
FUMES AND GASES can be dangerous.
4.a. 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 (see instructions on container or MSDS) 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 (TLV) 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.
4.b. 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.
4.c. Shielding 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.
4.d. Read and understand the manufacturer’s instruction for this equipment and the
consumables to be used, including the material safety data sheet (MSDS) and follow your
employer’s safety practices. MSDS forms are available from your welding distributor or from the
manufacturer.
