(Washington,

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

quaIit~,

the

results

are

complex.

Current

scientific

understanding

doe~

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.
