. .
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
cleariy
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.
