can
be hazardous.
PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN
AWAY. PACEMAKER WEARERS KEEP AWAY UNTIL CONSULTING YOUR DOCTOR.
In welding, as in most jobs, exposure to certain hazards occurs. Welding is safe when precautions are taken. The
safety information given below is only a summary of the more complete safety information found in the welding

Considerations About
Magnetic Fields
Welding
following is a quotation from the General Conclusions Section
Congress, Office of Technology Assessment, Biological
Effects of Power Frequency Electric & Magnetic Fields
Backg round 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.
