of
the
more
complete
safety
information
found
in
the
Safety

FUMES
AND
GASES
can
be
hazardous.
Welding
produces
fumes
and
gases.
Breathing
these
fumes
and
gases
can
be
hazardous
to
your
health.
Keep
your
head
out
of
the
fumes.
Do
not
breathe
the
fumes.
If
inside,
ventilate
the
area
andfor
use
exhaust
at
the
arc
to
remove
welding
fumes
and
gases.
If
ventilation
is
poor,
use
an
approved
air-supplied
respirator.
Read
the
Material
Safety
Data
Sheets
(MSDSs)
and
the
manufacturers
instructions
for
metals,
consumables,
coatings,
cleaners,
and
degreasers.
Work
in
a
confined
space
only
if
it
is
well
ventilated,
or
while
wearing
an
air-supplied
respirator.
Always
have
a
trained
watch-
person
nearby.
Welding
fumes
and
gases
can
displace
air
and
lower
the
oxygen
level
causing
injury
or
death.
Be
sure
the
breathing
air
is
safe.
Do
not
weld
in
locations
near
degreasing,
cleaning,
or
spraying
operations.
The
heat
and
rays
of
the
arc
can
react
with
vapors
to
form
highly
toxic
and
irritating
gases.
Do
not
weld
on
coated
metals,
such
as
galvanized,
lead,
or
cadmium
plated
steel,
unless
the
coating
is
removed
from
the
weld
area,
the
area
is
well
ventilated,
and
if
necessary,
while
wearing
an
air-supplied
respirator.
The
coatings
and
any
metals
containing
these
elements
can
give
off
toxic
fumes
if
welded.
