1.05.04 Fire and Explosions
To prevent fire, explosion, or rupture, be sure to observe the following precautions .
Spatter or hot base metals
produced during and
immediately after the welding
processes may cause fire.
Poor connections of cables or
defective contacts in any current
path on the base metal such as a
steel frame may cause
overheating due to conducting
current and may resulting in a
fire.
Explosion can be caused by the
welding arc produced on
containers that may have held
combustibles such as gasoline.
Rupture can be caused by
welding enclosed tanks or pipes.
Keep combustibles away from
scattered
welding spatter.
Cover combustibles that
cannot be removed with
incombustible shields.
Do not weld in the vicinity of
flammable gases.
Keep hot base metals
immediately after the welding
processes away from
combustibles.
When welding ceilings, floors
or walls, remove combustibles
hidden adjacent to them.
Tighten cable connections
securely and insulate them.
Connect work lead so that it is
positioned as close to the part
welded as possible.
Do not weld a gas pipe that
may have held any gas or an
enclosed tank or pipe
Have a fire extinguisher handy
in the vicinity of the welding
area in preparation for
emergency.
