•
Wear high top boots fully laced to prevent sparks from entering into the
boots.
•
Use fire-resistant boot protectors or spats strapped around the pant legs and
boot tops, to prevent sparks from bouncing in the top of the boots.
•
Remove all ignition sources such as matches and butane lighters from
pockets. Hot welding sparks may light the matches or ignite leaking lighter
fuel.
•
Wear gauntlet-type cuff leather gloves or protective sleeves of similar
material, to protect wrists and forearms. Leather is a good electrical insulator
if kept dry.
•
Direct any spark spray away from your clothing.
•
Wear leather aprons to protect your chest and lap from sparks when
standing or sitting.
•
Wear layers of clothing. To prevent sweating, avoid overdressing in cold
weather. Sweaty clothes cause rapid heat loss. Leather welding jackets are
not very breathable and can make you sweat if you are overdressed.
•
Wear a fire-resistant skull cap or balaclava hood under your helmet to
protect your head from burns and UV radiation.
•
Wear a welder's face shield to protect your face from UV radiation and flying
particles.
•
DO NOT wear rings or other jewelry.
•
DO NOT wear clothing made from synthetic or synthetic blends. The
synthetic fabric can burn vigorously, melt and produce bad skin burns.
Protect all areas of your body from injury during welding or cutting by wearing the
proper protective clothing and equipment.
Do not weld or cut unless wearing the necessary PPE as specified in this manual
and in ANSI Z49.1.

Considerations about Welding and the Effects of Low Frequency
Electric and Magnetic Fields
Welding current, as it flows through welding cables, will cause electromagnetic
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 human-health hazard."
However, studies are still going forth and evidence continues to be examined.
Until the final conclusions of the research are reached, you may wish to minimize
your exposure to electromagnetic fields when welding or cutting.
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 your body.
