Stud Welding Safety Precautions
WELDING SPARKS
Heat from flames and arcs can start fires. Hot slag or sparks can also cause fires and
explosions.
Remove all combustible materials from the work area or cover these materials with a protective
non
-
flammable tarp. Combustible materials include wood, fabrics, sawdust, liquid and gas fuels,
solvents, paints and coatings, paper, etc.
Hot sparks or hot metal can fall through cracks or crevices in floors or wall openings and cause a
hidden smoldering fire. Make certain that such openings are protected from hot sparks and metal.
ELECTRIC and MAGNETIC FIELDS
Electric current flowing through any conductor causes localized Electro
-
Magnetic Fields (EMF).
Welding and cutting current creates EMF around welding cables and welding machines.
Operators having pacemakers should consult their physician before welding, EMF may
interfere with some pacemakers
Exposure to EMF may have other health effects, which are unknown
Operators should use the following procedures to minimize exposure to EMF
Route the work cables together, secure them with electrical tape when possible
Never coil the work cable around any part of the body
Do not stand between the work cables
Connect the work cable to the work piece as close as possible to the area being welded
Keep welding power source and cables as far away from your body as possible
Electromagnetic fields can irrevocable erase magnetic data carriers (computer memory, credit
cards, security ID cards, etc.)
Electromagnetic fields may magnetize and damage watches or similar digital devices
PROTECT YOURSELF and OTHERS
Some welding, cutting, and gouging processes are noisy and require ear protection.
The arc, like the sun, emits ultraviolet (UV) and other radiation and may injure skin and
eyes. Hot metal can cause burns. Training in the proper use of welding processes and
equipment is essential to prevent accidents.
Wear flameproof type gloves, heavy long
-
sleeve shirt, cuff less trousers, and a welding helmet
or cap for hair protection, to protect against arc rays and hot sparks or hot metal. A flame-
proof apron may also be desirable as protection against radiated heat and sparks.
Hot sparks or metal can lodge in rolled up sleeves, trouser cuffs, or pockets. Sleeves and col-
lars should be kept buttoned, and open pockets eliminated from the front of clothing.
