D
D
Pacemaker wearers keep away.  
Wearers should consult their doctor before  
going near arc welding, gouging, or spot  
welding operations.  
Welding on closed containers, such as tanks,  
drums, or pipes, can cause them to blow up. Sparks  
can fly off from the welding arc. The flying sparks, hot  
workpiece, and hot equipment can cause fires and  
burns. Accidental contact of electrode to metal objects can cause  
sparks, explosion, overheating, or fire. Check and be sure the area is  
safe before doing any welding.  
NOISE can damage hearing.  
D
D
D
Protect yourself and others from flying sparks and hot metal.  
Do not weld where flying sparks can strike flammable material.  
Noise from some processes or equipment can  
damagehearing.  
Remove all flammables within 35 ft (10.7 m) of the welding arc. If  
this is not possible, tightly cover them with approved covers.  
D
Wear approved ear protection if noise level is  
high.  
D
Be alert that welding sparks and hot materials from welding can  
easily go through small cracks and openings to adjacent areas.  
D
D
Watch for fire, and keep a fire extinguisher nearby.  
CYLINDERS can explode if damaged.  
Be aware that welding on a ceiling, floor, bulkhead, or partition can  
cause fire on the hidden side.  
Shielding gas cylinders contain gas under high  
pressure. If damaged, a cylinder can explode. Since  
gas cylinders are normally part of the welding  
process, be sure to treat them carefully.  
D
D
Do not weld on closed containers such as tanks, drums, or pipes,  
unless they are properly prepared according to AWS F4.1 (see  
Safety Standards).  
Connect work cable to the work as close to the welding area as  
practical to prevent welding current from traveling long, possibly  
unknown paths and causing electric shock and fire hazards.

1-5. EMF Information  
Considerations About Welding And The Effects Of Low Frequency  
Electric And Magnetic Fields  
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.  
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  
committees 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.  
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:  
To reduce magnetic fields in the workplace, use the following  
procedures:  
Pacemaker wearers consult your doctor first. If cleared by your doctor,  
then following the above procedures is recommended.
