as
practical.
Insulate
work

according
to
instructions
in
Maintenance
Section
before

FUMES
AND
GASES
can
be
hazardous.
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
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
(MSDS5)
and
the
manufacturers
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.

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

fitted
with
a
propershade
offilterto
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

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
blowup.
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,
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
F4.1
(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

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

-
explosion
will
result.
Use
only
correct
shielding

cylinders,
regulators,
hoses,
and
fittings
designed
for
the
specific
application;
maintain
them
and
associated
parts

must
take

as
moving

Information
Considerations
About
Welding
And The
Effects
Of
Low
Frequency
Electric
And
Magnetic
Fields
Welding
current,
as
it
flows
through
welding
cables,
will
cause
electro
magnetic
fields.
There
has
been
and
still
is
some
concern
about
such
fields.
However,
after
examining
more
than
500
studies
spanning
17
years
of
research,
a
special
blue
ribbon
committee
of
the
National
Research
Council
concluded
that:
The
body
of
evidence,
in
the
committees
judgment,
has
not
demonstrated
that
exposure
to
power-
frequency
electric
and
magnetic
fields
is
a
human-health
hazard.
However,
studies
are
still
going
forth
and
evidence
continues
to
be
examined.
Until
the
final
conclusions
of
the
research
are
reached,
you
may
wish
to
minimize
your
exposure
to
electromagnetic
fields
when
welding
or
cutting.
To reduce
magnetic
fields
in
the
workplace,
use
the
following
procedures:
1.
Keep
cables
close
together
by
twisting
or
taping
them.
2.
Arrange
cables
to
one
side
and
away
from
the
operator.
3.
Do
not
coil
or
drape
cables
around
your
body.
4.
Keep
welding
power
source
and
cables
as
far
away
from
opera
tor
as
practical.
5.
Connect
work
clamp
to
workpiece
as
close
to
the
weld
as
possible.

then
following
the

is
recommended.
