Considerations About Welding And The Effects Of Low Frequency
Electric And Magnetic Fields
The following is a quotation from the General Conclusions Section of the
U.S. Congress, Office of Technology Assessment, Biological Effects of
Power Frequency Electric & Magnetic Fields Background Paper,
OTA-BP-E-53 (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 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 from opera-
tor as practical.
5. Connect work clamp to workpiece as close to the weld as possi-
ble.
About Pacemakers:
The above procedures are also recommended for pacemaker wearers.
