Background
Paper,

(Washington,

.
.
.
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
among
those
also
normally
recommended for
pacemaker
wearers.
Consult your doctor for
complete
information.
