SECTION 1 SAfETY PRECAuTIONS
WARNING: These Safety Precautions
are for your protection. They summarize
precautionary information from the refer-
ences listed in Additional Safety Informa-
tion section. Before performing any instal-
lation or operating procedures, be sure to
read and follow the safety precautions listed below
as well as all other manuals, material safety data
sheets, labels, etc. Failure to observe Safety Pre-
cautions can result in injury or death.
PROTECT YOURSELF AND OTH-
ERS -- Some welding, cutting, and
gouging processes are noisy and
require ear protection. The arc, like
the sun, emits ultraviolet (UV) and
other radiation and can injure skin and eyes. Hot
metal can cause burns. Training in the proper use
of the processes and equipment is essential to
prevent accidents. Therefore:
1. Always wear safety glasses with side
shields in any work area, even if welding helmets,
face shields, and goggles are also required.
2. Use a face shield fitted with the correct filter
and cover plates to protect your eyes, face, neck,
and ears from sparks and rays of the arc when op-
erating or observing operations. Warn bystanders
not to watch the arc and not to expose themselves
to the rays of the electric-arc or hot metal.
3. Wear flameproof gauntlet type gloves,
heavy long-sleeve shirt, cuffless trousers, high-
topped shoes, and a welding helmet or cap for
hair protection, to protect against arc rays and hot
sparks or hot metal. A flameproof apron may also
be desirable as protection against radiated heat
and sparks.
4. Hot sparks or metal can lodge in rolled up
sleeves, trouser cuffs, or pockets. Sleeves and
collars should be kept buttoned, and open pockets
eliminated from the front of clothing.
5. Protect other personnel from arc rays and
hot sparks with a suitable non-flammable partition
or curtains.
6. Use goggles over safety glasses when
chipping slag or grinding. Chipped slag may be
hot and can fly far. Bystanders should also wear
goggles over safety glasses.
FIRES AND EXPLOSIONS -- Heat
from flames and arcs can start
fires. Hot slag or sparks can also
cause fires and explosions. There-
fore:
1. Remove all combustible materials well
away from the work area or cover the materials
with a protective non-flammable covering. Com -
bustible materials include wood, cloth, sawdust,
liquid and gas fuels, solvents, paints and coatings,
paper, etc.
2. Hot sparks or hot metal can fall through
cracks or crevices in floors or wall openings and
cause a hidden smoldering fire or fires on the floor
below. Make certain that such openings are pro-
tected from hot sparks and metal.“
3. Do not weld, cut or perform other hot work
until the workpiece has been completely cleaned
so that there are no substances on the workpiece
which might produce flammable or toxic vapors. Do
not do hot work on closed containers. They may
explode.
4. Have fire extinguishing equipment handy
for instant use, such as a garden hose, water pail,
sand bucket, or portable fire extinguisher. Be sure
you are trained in its use.
5. Do not use equipment beyond its ratings.
For example, overloaded welding cable can over-
heat and create a fire hazard.
6. After completing operations, inspect the
work area to make certain there are no hot sparks
or hot metal which could cause a later fire. Use fire
watchers when necessary.
7. For additional information, refer to NFPA
Standard 51B, “Fire Prevention in Use of Cutting
and Welding Processes”, available from the Na-
tional Fire Protection Association, Batterymarch
Park, Quincy, MA 02269.
ELECTRICAL SHOCK -- Contact
with live electrical parts and ground
can cause severe injury or death.
DO NOT use AC welding current in
damp areas, if movement is con-
