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
•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
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.
