Special Considerations for Welding Painted Surfaces
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 utilized 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.
