FUMES
AND
GASES
can
be
hazardous.
-~
=~ul~

Keep
your
head
out
of the
fumes.
Do
not
breathe the fumes.

If
inside,
ventilate
the
area
and/or
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.
Welding
produces
fumes and
gases.
Breathing
these
fumes
and
gases
can
be hazardous
to
your
health.

ARC
RAYS
can
burn
eyes
and
skin
Arc
rays
from the
welding
process
produce
intense
visible
and invisible
(ultraviolet
and
infrared)
rays
that
can
burn
eyes
and
skin.
Sparks
fly
off
from
the
weld.

Wear
a
welding
helmetfitted
with
a
proper
shade
of
filter
to
protect
your
face and
eyes
when
welding
or
watching
(see
ANSI
Z49.1
and 287.1
listed in
Safety
Standards).

Wear
approved
safety glasses
with
side
shields under
your
helmet.

Use
protective
screens
or
barriers
to
protect
others from
flash
and
glare;
warn
others
not to
watch
the
arc.

Wear
protective
clothing
made
from
durable,
flame-resistant
material
(leather
and
wool)
and
foot
protection.
WELDING
can
cause
fire
or
explosion.
Welding
on
closed
containers,
such
as
tanks,
drums,
or
pipes,
can cause
them
to
blow
up.
Sparks
can
fly
off
from
the
welding
arc.
The
flying
sparks,
hot
workpiece,
and hot
equipment
can
cause
fires
and burns.
Accidental
contact
of
electrode
to
metal
objects
can
cause
sparks, explosion,
overheating,
orfire. Check
and
besurethe
area
is
safe before
doing
any
welding.

Protect
yourself
and
others
from
flying
sparks
and
hot
metal.

Do
not
weld
where
flying
sparks
can
strike
flammable
material.

Remove all flammables
within
35
ft
(10.7
m)
of
the
welding
arc.
If
this
is
not
possible, tightly
cover
them
with
approved
covers.

Be
alert
that
welding
sparks
and hot
materials from
welding
can
easily
go
through
small cracks and
openings
to
adjacent
areas.

Watch
for
fire,
and
keep
a
fire
extinguisher nearby.

Be
aware
that
welding
on a
ceiling,
floor, bulkhead,
or
partition
can cause
fire
on
the
hidden
side.

Do
not weld
on
closed containers such
as
tanks,
drums,
or
pipes,
unless
they
are
properly
prepared
according
to
AWS
F4.1
(see
Safety
Standards).

Connect
work
cable
to
the work
as
close
to
the
welding
area as
practical
to
prevent
welding
current
from
traveling
long,
possibly
unknown
paths
and
causing
electric
shock
and fire
hazards.

Do
not
use
welder to
thaw
frozen
pipes.

Remove
stick
electrode from holder
or
cut
off
welding
wire
at
contact
tip
when
not
in
use.

Wear
oil-free
protective
garments
such
as
leather
gloves, heavy
shirt,
cuffless
trousers,
high
shoes,
and
a
cap.

Remove
any
combustibles,
such
as a
butane
lighter
or
matches,
from
your
person
before
doing
any
welding.
FLYING METAL
can
Injure
eyes

Welding, chipping,
wire
brushing,
and
grinding
cause
sparks
and
flying
metal. As
welds
cool,
they
can
throw
off
slag.

Wear
approved
safety
glasses
with
side
shields
even
under
your
welding
helmet.


Wearers
should consult
their
doctor
before
going
near

welding operations.
NOISE
can
damage
hearing.
Noise
from
some
processes
or
equipment
can
damage
hearing.

Wear
approved
ear
protection
if noise level
is
high.
CYLINDERS
can
explode
if
damaged.
Shielding
gas
cylinders
contain
gas
under
high
pressure.
If
damaged,
a
cylinder
can
explode.
Since
gas
cylinders
are
normally
part
of the
welding
process,
be
sure
to treat
them
carefully.

Protect
compressed
gas
cylinders
from
excessive
heat,
mechanical
shocks,
slag,
open
flames,
sparks,
and
arcs.

Install
cylinders
in
an
upright position by securing
to a
stationary
support
or
cylinder
rack
to
prevent
falling
or
tipping.

Keep
cylinders
away
from
any
welding
or
other electrical circuits.

Never
drape
a
welding
torch
over a
gas
cylinder.

Never
allow
a
welding
electrode
to
touch
any
cylinder.

Never weld
on a
pressurized cylinder
-
explosion
will
result.
 Use
only
correct
shielding
gas
cylinders, regulators,
hoses,
and
fittings
designed
for the
specific
application;
maintain
them and
associated
parts
in
good
condition.
 Turn
face
away
from

valve.

Keep
protective


Read
and
follow
