When welding or cutting steel coated with a certain paint systems,
the worker is exposed to decomposition products (metal fumes, gases
or vapors, particulate) which vary depending on the type of process
being used to weld or cut, the nature of the base metal, and the type
of coating system. The following control procedures should be uti-
lized when one is welding or cutting coated steel:
• Use a power brush or grinding wheel to strip the coating from the
steel in the vicinity where the cut or weld is to be made. Remove
the paint far enough from the weld to prevent any remaining paint
from becoming heated and bubbling. If this happens, continue to
brush or grind the paint away.
• A toxic dust respirator and eye protection should be used while
stripping the paint.
• Welder should be outfitted with a fresh air supplied respirator and
other personal protective equipment required for welding.
• Other employees should be removed from the area or told to stand
back a minimum of 10 feet from the welder. Do not be in direct
line with the weld fumes.
• Use a local exhaust hood to remove fumes during the welding or
cutting operation if one is available.
