WARNING
This product, when used for welding or
cutting, produces fumes or gases which
contain chemicals know to the State of
California to cause birth defects and, in some
cases, cancer. (California Health & Safety code
Sec. 25249.5 et seq.)
NOTE
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-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.
