FUMESAND
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
and/or
use
exhaustatthe
arc
to
remove
welding
fumes
and
gases.
If
ventilation
is
poor,
use
an
approved
air-supplied
respirator.
Read
the
Material
Safety
Data
Sheets
(MSDS5)
and
the
manufacturers
instructions
for
metals,
consumables,
coatings,
cleaners,
and
degreasers.

only
ifitis
well
ventilated,
or
while
wearing
an
air-supplied
respirator.
Always
haveatrained

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,orspraying
operations.
The
heat
and
rays
of
the
arc
can
react
with
vapors
to
form
highly
toxic
and
irritating
gases.
Do
not
weld
on
coated

such
as
galvanized,
lead,
or
cadmium
plated
steel,
unless
the

rays
that
can
burn

fly
off
from
the

before
doing
any
welding.
Protect
yourself
and
others
from
