WELDING AND CUTTING SPARKS can cause fire or explosion
.
6.a. Remove fire hazardous from the welding area. If this is not possible, cover them to prevent
the welding sparks from starting a fire. Remember that welding sparks and hot materials
from welding can easily go through small cracks and openings to adjacent areas. Avoid
welding near hydraulic lines. Have a fire extinguisher readily available.
6.b. Where compressed gases are to be used at the job site, special precautions should be used
to prevent hazardous situations.
6.c. When not welding, make certain no part of the electrode circuit is touching the work or
ground. Accidental contact can cause overheating and create a fire hazard.
6.d. Do not heat, cut or weld tanks, drums or containers until the proper steps have been taken
to insure that such procedures will not cause flammable or toxic vapors from substances
inside. They can cause an explosion even though they have been “cleaned”.
6.e. Vent hollow castings or containers before heating, cutting or welding. They may explode.
6.f. Sparks and spatter are thrown from the welding arc. Wear oil free protective garments such
as leather gloves, heavy shirt, high shoes and a cap over your hair. Wear ear plugs when
welding out of position or in confined places. Always wear safety glasses with side shields
when in a welding area.
6.g. Connect the work cable to the work as close to the welding area as practical. Work cables
connected to the building framework or other locations away from the welding area
increase the possibility of the welding current passing through lifting chains, crane cables
or other alternate circuits. This can create fire hazards or overheat lifting chains or cable
until they fail.
6.h. Also see item 1.c.
6.i. Do not use a welding power source for pipe thawing.
