WarnIng:
These Safety Precautions are
for your protection. They summarize pre-
cautionary information from the references
listed in Additional Safety Information sec-
tion. Before performing any installation or operating
procedures, be sure to read and follow the safety precau-
tions listed below as well as all other manuals, material
safety data sheets, labels, etc. Failure to observe Safety
Precautions can result in injury or death.
protect Yourself anD others --
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 operating
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 protec-
tion 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. therefore:
1. Remove all combustible materials well away from
the work area or cover the materials with a protec-
tive non-flammable covering. Combustible 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 hid-
den smoldering fire or fires on the floor below. Make
certain that such openings are protected 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 ex-
ample, overloaded welding cable can overheat 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 National Fire Protec-
tion 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 confined, or if there is
danger of falling.
