INTRODUCTION
-
We
learn
by
experience.
Learning
safety
through
personal
experience,
like
a
child
touching
a
hot
stove
is
harmful,
wasteful,
and
un
wise.
Let
the
experience
of
others
teach
you.
Safe
practices
developed
from
experience
in
the
use
of
welding
and
cutting
are
described
in
this
manual.
Research,
development,
and
field
experience
have
evolved
reliable
equipment
and
safe
installation,
opera
tion,
and
servicing practices.
Accidents
occur
when
equipment
is
improperly
used
or
maintained.
The
reason
for
the
safe
practices
may
not
always
be
given.
Some
are
based
on
common
sense,
others
may
require
technical volumes
to
explain.
It
is
wiser
to
follow
the
rules.
Read
and
understand these safe
practices
before
at
tempting
to
install,
operate,
or
service
the
equipment.
Comply
with
these
procedures
as
applicable
to
the
par
ticular
equipment
used
and
their instruction
manuals,
for
personal safety
and for the
safety
of
others.
Failure
to
observe
these
safe
practices
may
cause
serious
injury
or
death.
When
safety
becomes
a
habit,
the
equipment
can
be used
with
confidence.
These safe
practices
are
divided
into
two
Sections:
1
-
General
Precautions,
common
to
arc
welding
and
cutting;
and
2
-
Arc
Welding
(and
Cutting)
(only).
Reference
standards:
Published
Standards
on
safety
are
also
available for additional
and
more
complete
pro
cedures than those
given
in
this manual.
They
are
listed
in
the
Standards
Index in
this
manual. ANSI
Z49.1
is
the
most
complete.
The
National
Electrical
Code,
Occupational
Safety
and
Health
Administration,
local
industrial
codes,
and
local
inspection
requirements
also
provide
a
basis
for
equip
ment
installation,
use,
and service.
1-2.
GENERAL
PRECAUTIONS
Different
arc
welding
processes,
electrode
alloys,
and fluxes
can
produce
different
fumes,
gases,
and
radiation
levels.
In
addition
to
the
information
in this
manual,
be
sure
to
consult
flux
and elec
trode manufacturers
for
specific
technical
data
and
precautionary
measures
concerning
their
material.
A.
Burn
Prevention
Wear
protective
clothing
-
gauntlet
gloves
designed
for
use
in
welding,
hat,
and
high
safety-toe
shoes.
Button
shirt collar
and
pocket flaps,
and
wear
cuffless
trousers
to
avoid
entry
of
sparks
and
slag.
Wear
helmet
with
safety
goggles
or
glasses
with
side
shields
underneath,
appropriate
filter lenses or
plates
(protected
by
clear
cover
glass).
This
is
a
MUST
for
welding
or
cutting,
(and
chipping)
to
protect
the
eyes

B. Toxic Fume
Prevention
Severe
discomfort,
illness
or
death
can
result
from
fumes,
vapors,
heat,
or
oxygen
enrichment
or
depletion
that
welding
(or
cutting)
may
produce.
Prevent
them
with
adequate
ventilation
as
described
in
ANSI
Stan
dard
Z49.1
listed
1
in
Standards
index.
NEVER ventilate
with
oxygen.
Lead
-,
cadmium
-,
zinc
-,
mercury
-,
and
beryllium
-
bearing
and similar
materials,
when welded
(or cut)
may
produce
harmful concentrations
of
toxic
fumes.
Ade
quate
local
exhaust ventilation
must
be
used,
or
each
person
in
the
area as
well
as
the
operator
must
wear an
air-supplied respirator.
For
beryllium,
both
must
be
us
ed.
Metals
coated
with
or
containing
materials
that
emit
toxic
fumes
should
not
be heated
unless
coating
is
removed
from
the
work
surface,
the
area
is well
ven
tilated,
or
the
operator
wears an
air-supplied respirator.
Work
in
a
confined
space
only
while it is
being
ven
tilated
and,
if
necessary,
while
wearing
an
air-supplied
respirator.
Gas
leaks
in
a
confined
space
should
be
avoided.
Leaked
gas
in
large
quantities
can
change
oxygen
con
centration
dangerously.
Do
not
bring
gas
cylinders
into
a
confined
space.
Leaving
confined
space,
shut OFF
gas
supply
at
source
to
prevent
possible
accumulation
of
gases
in
the
space
if
downstream
valves
have
been
accidently
opened
or
left
open.
Check
to
be
sure
that
the
space
is
safe
before
re-entering
it.
Vapors
from
chlorinated
solvents
can
be
decomposed
by
the
heat of
the
arc
(or flame)
to
form
PHOSGENE,
a
highly
toxic

C.
Fire
and
Explosion
Prevention
Causes
of
fire
and
explosion
are:
combustibles
reached
by
the
arc,
flame,
flying
sparks,
hot
slag
or
heated
material;
misuse
of
compressed
gases
and
cylinders;
and
short
circuits.
BE
AWARE
THAT
flying
sparks
or
falling
slag
can
pass
through
cracks,
along
pipes,
through
windows or
doors,
and
through
wall
or
floor
openings,
out
of
sight
of the
goggled
operator.
Sparks
and
slag
can
fly
35
feet.
To
prevent
fires
and
explosion:
Keep
equipment
clean
and
operable,
free
of
oil,
grease,
and
(in
electrical
parts)
of
metallic
particles
that
can
cause
short
circuits.
If
combustibles
are
in
area,
do
NOT
weld
or
Cut.
Move
the
work
if
practicable,
to
an
area
free
of
combustibles.
Avoid
paint spray
rooms,
dip
tanks,
storage
areas,
yen
tilators.
If the
work cannot
be
moved,
move
com
bustibles
at
least
35
feet
away
out
of
reach
of
sparks
and
heat;
or
protect
against
ignition
with
suitable
and
snug-fitting,
fire-resistant
covers
or
shields.
Walls
touching
combustibles
on
opposite
sides
should
not
be
welded
on
(or
cut).
Walls,
ceilings,
and
floor
near
work
should
be
protected
by
heat-resistant
covers
or
shields.
Fire
watcher
must
be
standing
by
with
suitable
fire
ex
tinguishing
equipment
during
and
for
some
time
after
welding
or
cutting
if:
a.
appreciable
combustibles
(including
building
construction)
are
within
35
feet
b.
appreciable
combustibles
are
further
than
35
feet
but
can
be
ignited
by

c.
openings
(concealed
or
visible)
in
floors or
walls
within 35
feet
may
expose
com

to
sparks
d.
combustibles
adjacent
to
walls, ceilings,
roofs,
or
metal
partitions
can
be
ignited
by
radiant
or
conducted
heat.
Hot
work
permit
should
be
obtained
before
operation
to
ensure
supervisors
approval
that
adequate
precautions
have
been
taken.
After
work
is
done,
check
that
area
is
free
of
sparks,
glowing
embers,
and
flames.
An
empty
container
that held
combustibles,
or
that
can
produce
flammable
or
toxic
vapors
when
heated,
must
never
be
welded
on
or

Flash
goggles
with side
shields
MUST
be
worn
under
the
helmet
to
give
some
protection
to
the
eyes
should
the helmet
not
be lowered
over
the face before
an
arc
is
struck.
Looking
at
an arc
momentarily
with
unprotected
eyes
(particularly
a
high
intensity gas-shielded
arc)
can
cause
a
retinal
burn
that
may
leave
a
permanent
dark
area
in
the
field
of
vision.
3. Protection
of
Nearby
Personnel
Enclosed

To
protect
against
shock:
Keep
body
and
clothing
dry.
Never
work in
damp
area
without
adequate
insulation
against
electrical
shock.
Stay
on a
div
duckboard,
or
rubber
mat
when
damp
ness or
sweat
can
not
be
avoided.
Sweat,
sea
water,
or
moisture between
body
and
an
electrically
HOT
part
-
or
grounded
metal
-
reduces
the
body
surface
electrical
resistance,
enabling
dangerous
and
possibly
lethal
currents
to
flow
through
the
body.
1.
Grounding
the
Equipment
When
arc
welding
equipment
is
grounded
according
to
the
National
Electrical
Code,
and
the
work
is
grounded
according
to
ANSI Z49.1
Safety
In
Welding
And
Cut
ting,
a
voltage may
exist between
the electrode and
any
conducting
object.
Examples
of
conducting
obiects
include,
but
are
not
limited
to,
buildings,
electrical
tools,
work
benches,
welding
power
source
cases,
workpieces,
etc.
Never touch
the
electrode and
any
metal
object
unless the
welding
power
source
is
off.
When
installing,
connect
the
frames
of
each
unit
such
as
welding
power
source,
control,
work
table,
and
water
circulator to
the
building
ground.
Conductors
must
be
adequate
to
carry
ground
currents
safely.
Equipment
made
electrically
HOT
by
stray
current
may
shock,
possibly
fatally.
Do
NOT
GROUND
to
electrical
conduit,
or
to
a
pipe carrying
ANY
gas
or
a
flammable
li
quid
such
as
oil
or
fuel.
Three-phase
connection.
Check
phase requirements
of
equipment
before
installing.
If
only
3-phase
power
is
available,
connect
single-phase
equipment
to
only
two
wires
of the
3-phase
line.
Do
NOT
connect
the
equip
ment
ground
lead
to
the
third
(live)
wire,
or
the
equip
ment
will become
electrically
HOT
-
a
dangerous
condi
tion
that
can shock,
possibly
fatally.
Before
welding,
check
ground
for
continuity.
Be
sure
conductors
are
touching
bare
metal
of
equipment
frames
at
connections.
If
a
line cord
with
a
ground
lead
is
provided
with the
equipment
for
connection
to
a
switchbox,
connect
the
ground
lead
to
the
grounded
switchbox.
If
a
three-
prong
plug
is
added for
connection
to
a
grounded
mating
receptacle,
the
ground
lead
must
be
connected
to
the
ground
prong
only.
If the
line cord
comes
with
a
three-prong
plug,
connect
to
a
grounded
mating
recep
tacle.
Never
remove
the
ground
prong
from
a
plug,
or
use a
plug
with
a
broken
off
ground
prong.
