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

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

Considerations

Background

Paper~

OTA-BP-E-53

(Washington,

DC:

U.S.

Government

Printing

Office,

May

1989):..

.

there

is

now

a

very

large

volume

of

scientific

findings

based

on

experiments

at

the

cellularlevel

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

among

those

also

normally

recommended

for

pacemaker

wearers.

Consult

your

doctor

for

complete

information.
