Considerations About Welding And The Effects Of Low Frequency Electric And Magnetic Fields
Welding current, as it flows through welding cables, will cause electro- magnetic fields. There has been and still is some concern about such fields. However, after examining more than 500 studies spanning 17 years of research, a special blue ribbon committee of the National Research Council concluded that: “The body of evidence, in the committee’s judgment, has not demonstrated that exposure to power- frequency electric and magnetic fields is a
To reduce magnetic fields in the workplace, use the following procedures:
1.Keep cables close together by twisting or taping them, or using a cable cover.
2.Arrange cables to one side and away from the operator.
3.Do not coil or drape cables around your 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 Implanted Medical Devices:
Implanted Medical Device wearers should consult their doctor and the device manufacturer before performing or going near arc welding, spot welding, gouging, plasma arc cutting, or induction heating operations. If cleared by your doctor, then following the above procedures is recom- mended.
