nology Assessment, Biological Effects of Power Frequency Electric & Magnetic Fields - Background Paper,
OTA-BP-E-63 (Washington, DC: U.S. Government Printing 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 and 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 cable around the body.
4. Keep welding power source and cables as far away from body as practical.
ABOUT PACEMAKERS:
The above procedures are among those also normally recommended for pacemaker wearers.
Consult your doctor for complete information.
