HOT SURFACES(Cont'd.)-
Sparks-
Sparks form as the plasma arc torch vaporizes metal. These sparks are tiny droplets of extremely
hot molten metal and are a possible fire hazard. The volume of sparks formed and the area over
which they are scattered depend on several variables. These variables include the type and
thickness of the material being cut, the cutting current, and the feed rate. Where practical, keep
all combustible material at least 35 ft. (10.7 m) away from the plasma arc work area. Where this is
not practical, protect all combustible materials with close fitting, flame proof covers or shields.
Protect wooden or other combustible floors by covering them with sand or installing fire-resistant
shields. Shield any wall openings, floor openings, cracks, ducts, or conveyors within 35 ft. (10.7 m)
of the torch to prevent sparks from passing into adjacent areas.
