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.
