and do not start engine until fumes have been eliminated.
WELDING SPARKS can cause fire or
explosion.
Welding on closed containers, such as tanks, drums, or pipes, can cause
them to explode. Flying sparks from the welding arc, hot work piece, and hot
equipment can cause fires and burns. Accidental contact of electrode to metal
objects can cause sparks, explosion, overheating, or fire. Check and be sure
the area is safe before doing any welding
Remove fire hazards material 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.
Where compressed gases are to be used at the job site, special precautions
should be used to prevent hazardous situation.
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.
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”.
Vent hollow castings or containers before heating, cutting or welding. They
may explode.
Sparks and spatter are thrown from the welding arc. Wear oil free protective
garments such as leather gloves, heavy shirt, cuff less trousers, high shoes
and a cap over your hair. Wear earplugs when welding out of position or in
confined places. Always wear safety glasses with side shields when in a
