sleeves, fire resistant leggings, or
apron. Hot sparks or metal can lodge
in rolled up sleeves, trouser cuffs, or
pockets. Sleeves and collars should
be kept buttoned and pockets
eliminated from the shirt front.
Have fire extinguishing equipment
handy for immediate use! A portable
chemical fire extinguisher, type ABC,
is recommended.
• Wear ear plugs when welding
overhead to prevent spatter or slag
from falling into ear.
• Make sure welding area has a good,
solid, safe floor, preferably concrete or
masonry, not tiled, carpeted, or made
of any other flammable material.
• Protect flammable walls, ceilings, and
floors with heat resistant covers or
shields.
Check welding area to make sure it is
free of sparks, glowing metal or slag,
and flames before leaving the welding
area.
FUME HAZARDS
WARNING
FUMES, GASSES, AND VAPORS CAN
CAUSE DISCOMFORT, ILLNESS, AND
DEATH! To reduce risk of discomfort,
illness, or death, read, understand, and
follow the following safety instructions. In
addition, make certain that anyone else
that uses this welding equipment or is a
bystander in the welding area,
understands and follows these safety
instructions as well.
• Do not weld in an area until it is
checked for adequate ventilation as
described in ANSI standard #Z49.1. If
ventilation is not adequate to
exchange all fumes and gasses
generated during the welding process
with fresh air, do not weld unless you
(the welder) and all bystanders are
wearing air-supplied respirators.
• Do not heat metals coated with, or
that contain, materials that produce
toxic fumes (such as galvanized
6
steel), unless the coating is removed.
Make certain the area is well
ventilated, and the operator and all
bystanders are wearing air-supplied
respirators.
Do not weld, cut, or heat lead, zinc,
cadmium, mercury, beryllium, or
similar metals without seeking
professional advice and inspection of
the ventilation of the welding area.
These metals produce EXTREMELY
TOXIC fumes which can cause
discomfort, illness, and death.
• Do not weld or cut in areas that are
near chlorinated solvents. Vapors from
chlorinated hydrocarbons, such as
trichloroethylene and
perchloroethylene, can be
decomposed by the heat of an electric
arc or its ultraviolet radiation. These
actions can cause PHOSGENE, a
HIGHLY TOXIC gas to form, along
with other lung and eye-irritating
gasses. Do not weld or cut where
these solvent vapors can be drawn
into the work area or where the
ultraviolet radiation can penetrate to
areas containing even very small
amounts of these vapors.
• Do not weld in a confined area unless
it is being ventilated or the operator
(and anyone else in the area) is
wearing an air-supplied respirator.
• Stop welding if you develop
momentary eye, nose, or throat
irritation as this indicates inadequate
ventilation. Stop work and take
necessary steps to improve ventilation
in the welding area. Do not resume
welding if physical discomfort persists.
