NOTE
Conside r ations About Welding And The Effects of
Low F r equency Elect r ic and Magnetic Fields
The following is a quotation f r om the Gene r al Conclusions Sec-
tion of the U.S. Cong r ess, Office of Technology Assessment, Bio-
logical Effects of Powe r F r equency Elect r ic & Magnetic Fields -
Backg r ound Pape r , OTA-BP-E-63 (Washington, DC: U.S. Gov-
e r nment P r inting Office, May 1989): “...the r e is now a ve r y la r ge
volume of scientific findings based on expe r iments at the cellula r
level and f r om studies with animals and people which clea r ly
establish that low f r equency magnetic fields and inte r act with,
and p r oduce changes in, biological systems. While most of this
wo r k is of ve r y high quality, the r esults a r e complex. Cu rr ent
scientific unde r standing does not yet allow us to inte r p r et the
evidence in a single cohe r ent f r amewo r k. Even mo r e f r ust r ating,
it does not yet allow us to d r aw definite conclusions about ques-
tions of possible r isk o r to offe r clea r science-based advice on
st r ategies to minimize o r avoid potential r isks.”
To r educe magnetic fields in the wo r kplace, use the following
p r ocedu r es.
1. Keep cables close togethe r by twisting o r taping them.
2. A rr ange cables to one side and away f r om the ope r ato r .
3. Do not coil o r d r ape cable a r ound the body.
4. Keep welding powe r sou r ce and cables as fa r away f r om
body as p r actical.
