ARC RAYS
can
burn eyes and skin.
Arc rays from the
welding
process
produce
intense
visible and invisible
(ultraviolet
and
infrared)
rays
that
can
bum
eyes and
skin.
Sparks fly
off from the
weld.
Wear
a
welding
helmet fitted with
a
proper shade of filter
to
protect
your face and eyes when
welding
or
watching (see
ANSI Z49.1
and Z87.1 listed
in
Safety Standards).
Wear
approved safety glasses
with side shields under your
helmet.
Use
protective
screens
or
bafflers
to
protect
others from flash and
glare;
warn
others
not to
watch the
arc.
Wear
protective dothing
made from
durable,
flame-resistant mate
rial
(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
bums. Accidental contact of electrode
to
metal
objects
can cause
sparks, explosion, overheating,
or
fire. Check and be
sure
the
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.i
(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.
BUILDUP OF GAS
can
injure
or
kill.
Shut off
shielding
gas
supply
when not in
use.
Always
ventilate
confined spaces
or
use
approved air-supplied respirator.
HOT PARTS
can cause severe
burns.
Do
not
touch hot
parts
bare handed.
Allow
cooling period
before
working
on
gun
or
torch.
MAGNETIC FIELDS
can
affect
pacemakers.
Pacemaker
wearers
keep
away.
Wearers should consult their doctor before
going
near
arc
welding, gouging,
or
spot
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,
mechani
cal
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 fit
tings designed
for the
specific application;
maintain them and
associated
parts
in
good
condition.
Tum face away from valve outlet when
opening cylinder
valve.
Keep protective
cap in
place
over
valve
except
when
cylinder
is in
use or
connected for
use.
Read and follow instructions
on
compressed
gas
cylinders,
associated
equipment,
and CGA
publication
P-i listed in
Safety
Standards.
