General Safety Information
(Continued)
Fire
hazard!
Do not weld on containers
or pipes that contain or
have contained flammable
materials or gaseous or liquid
combustibles.
Arc
welding
closed cylinders or containers
such as tanks or drums
can cause explosion if
not properly vented! Verify that any
cylinder or container to be welded has
an adequate ventilation hole, so that
expanding gases can be released.
Do not
breathe
fumes that are produced by
the arc welding operation.
These fumes are dangerous.
If the welding area cannot be
adequately ventilated, be sure to use an
air-supplied respirator.
• Keep the head and face out of the
welding fumes.
• Do not perform electric arc welding
operations on metals that are
galvanized or cadmium plated, or
contain zinc, mercury, or beryllium
without completing the following
precautions:
a. Remove the coating from the
base metal.
b. Make sure that the welding area
is well ventilated.
c. Use an air-supplied respirator.
Extremely toxic fumes are created when
these metals are heated.
The electromagnetic field
that is generated during
arc welding may interfere
with the operation of various electrical
and electronic devices such as cardiac
pacemakers. Persons using such devices
should consult with their physician prior
to performing any electric arc welding
operations.
• Route the electrode and work
cables together and secure with
tape when possible.
• Never wrap arc welder cables
around the body.
• Always position the electrode and
work leads so that they are on the
same side of the body.
• Exposure to electromagnetic fields
during welding may have other
health effects which are not known.
Always be sure that
the welding area
is secure and free of hazards (sparks,
flames, glowing metal or slag) prior to
leaving. Be sure that the equipment is
turned off and electrode is removed. Be
sure that cables are loosely coiled and
out of the way. Be sure that all metal
and slag has cooled.
