3. FUMES AND GASES -
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.

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.

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.

Follow your employer's safety practices.
