will
result.
7.
Use
only
correct
shielding
gas
cylinders,
regulators,
hoses,
and
fittings
designed
for
the
specific
application;
maintain
them
and
associated
parts
in
good

equipment,
and
CGA
publication
P-i
listed
in
Safety

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,
or
fire.
Check
and
be
sure
the
area
is
safe before
doing
any
welding.
1.
Protect
yourself
and
others
from
flying
sparks
and
hot
metal.
2.
Do
not
weld
where
flying
sparks
can
strike
flammable
material.
3.
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
properly
prepared
according
to
AWS
F4.
1
(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
tip
when
not
in
use.
11.
Wear
oil-free
protective
garments
such
as
leather
gIove~,
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.

Considerations
About
Welding
And
The
Effects
Of
Low
Frequency
Electric
And
Magnetic
Fields
The

from

Background
Paper,
OTA-BP-E-53
(Washington,

U.S.
Government
Printing
Office,
May
1989):
.
. .
there
is
now
a
very
large
volume
of
scientific
findings
based
on
experiments
at
the
cellular level
and
from
studies
with
animals
and
people
which
clearly
establish
that
low
frequency
magnetic
fields
can
interact
with,
and
produce
changes
in,
biological
systems.
While
most
of
this
work
is
of
very
high
quality,
the
results
are
complex.
Current
scientific
understanding
does
not
yet
allow
us
to
interpret
the
evidence
in
a
single
coherent
framework.
Even
more
frustrating,
it
does
not
yet
allow
us
to
draw
definite
conclusions
about
questions
of
possible
risk
or
to
offer
clear
science-based
advice
on
strategies
to
minimize
or
avoid
potential
risks.
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
the
body.
4.
Keep
welding
power
source
and
cables
as
far
away
as
practical.
5.
Connect
work
clamp
to
workpiece
as
close
to
the
weld
as
possible.
About
Pacemakers:
The
above
procedures
are
also
recommended
for
pacemaker
wearers.
Consult
your
doctor
for
complete
information.
