FUMES
AND
GASES
can
be
hazardous
to
your health.
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 breath the fumes.
If
inside,
ventilate the
area
and/or
use
exhaust
at
the
arc
to
remove
welding
fumes and gases.
3.
If ventilation is poor,
use an
approved air-supplied respirator.
4.
Read the Material
Safety
Data Sheets
(MSDSs)
and the
manufacturers
instruction for
metals, consumables,
coatings,
and cleaners.
5.
Work in
a
confined space
only
if it is well
ventilated,
or
while
wearing
an
air-supplied respirator. Shielding
gases used for
welding
can
displace
air
causing injury
or
death. Be
sure
the
breathing
air is safe.
6.
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.
7.
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.
Chipping
and
grinding
cause
flying
metal. As welds
cool,
they
can
throw off
slag.
