WELDING
CAN
BE
HAZARDOUS.
ALWAYS
PROTECT
YOURSELF
AND
OTHERS
FROM
POSSIBLE
INJURY
OR
DEATH.
KEEP
CHILDREN
AWAY.
Operators
who

FUMES
and
OXYGEN
DEPLETION
♦
Only
weld
in
areas
or
rooms
where
adequate
ventilation
of
weld
gases
is
possible
and
where
there
is
not
fire,
smoke
or
explosion
hazards.
♦
When
working
in
a
confined
space
always
have
trained
support
personnel
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
arcs
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.
The
coating
must
be
removed
from
the
area
to
be
welded.
Coatings
and
metals
containing
above
elements
can
generate
toxic
fumes
when
heated
to
welding
temperature.
