gas
cylinders
contain

If
damaged,
a
cylinder
can
explode.
Since
gas

to
treat
them
carefully.
1.
Protect

a
welding
electrode
to
touch
any

application;
maintain
them
and
associated
parts
in

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.
4.
Be
alert
that
welding
sparks
and
hot
materials
from
welding
can
easily
go
through
small
cracks
and
openings
to
adjacent
areas.
5.
Watch
for
fire,
and
keep
a
fire
extinguisher
nearby.
6.
Be
aware
that
welding
on
a
ceiling,
floor,
bulkhead,
or
partition
can
cause
fire
on
the
hidden
side.
7.
Do
not
weld
on
closed
containers
such
as
tanks,
drums,
or
pipes,
unless
they
are
property

(see
Safety
Standards).
8.
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.
9.
Do
not
use
welder
to
thaw
frozen
pipes.
10.
Remove
stick
electrode
from
holder
or
cut
off
welding
wire
at
contact

when
not
in
use.
11.
Wear
oil-free
protective
garments
such
as
leather
gloves,
heavy
shirt,
cuffless
trousers,
high
shoes,
and
a
cap.
12.
Remove
any
combustibles,
such
as
a
butane
lighter
or
matches,
from
your
person
before
doing
any
welding.
