a. Remove fire hazards 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.
b. Where compressed gases are to be used at the job site, special precautions should be used to prevent
hazardous situations.
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.
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”.
e. Vent hollow castings or containers before heating, cutting or welding. They may explode.
f. Sparks and spatter are thrown from the welding arc. Wear oil free protective garments such as leather
gloves, heavy shirt, cuffless trousers, 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.
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 cables until they fail.
