Safe

practices

have

developed

from

past

experience

in

the

use

of

welding

These

practices

must

be

learned

through

study

and

training

before

using

this

equipment.

Anyone

not

having

extensive

training

in

welding

and

cutting

practices

should

not

Certain

of

the

practices

apply

to

equipment

connected

WELDING

can

cause

off

from

arc.

The

flying

sparks

and

hot

metal,

weld

spatter,

work-

piece,

and

hot

equipment

can

cause

fires

and

burns.

Accidental

contact

of

to

metal

objects

can

cause

sparks,

or

fire.

.

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.

.

Bealertthat

welding

sparks

and

hot

materials

from

welding

can

easily

go

through

small

cracks

and

openings

to

adjacent

areas.

FLYING

SPARKS

AND

HOT

METAL

can

cause

Chipping

and

grinding

cause

they

can

to

treat

and

the

‚

Work

in

a

confined

space

only

if

it

is

well

ventilated,

or

while

wearing

an

air-supplied

respirator.

Shielding

gases

used

for

welding

can

displace

air

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.

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.

.

Do

not

weld

on

closed

containers

such

as

tanks

or

drums.

.

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

to

thaw

Considerations

Background

Paper,

OTA-BP-E-63

(Washington,

DC:

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.

3.

Do

not

coil

or

drape

cables

around

the

body.

2.

Arrange

cables

to

one

side

and

away

from

the

operator.

4.

Keep

welding

power

source

and

cables

as

far

away

from

body

as

practical.

About

Pacemakers:

The

above

procedures

are

among

those

also

normally

recommended

for

pacemaker

wearers.

Consult

your

doctor

for

complete

information.
