Welding Hazards and Precautions
Electric Shock
Avoid the possibility of dangerous electric shock by using insulated electrode holders and wearing dry leathers and gloves.
- When possible, avoid using arc-welding equipment in wet or damp areas.
- Never perform arc-welding in an area that is not well ventilated.
Electric Shock Protection When Welding Safely
Flying Sparks and Molten Metal
Flying sparks usually accompany arc welding. These present a hazard if they strike unprotected skin, lodge on flammable clothing, or hit any other flammable material.
- When arc welding, wear suitable weight clothing and cuffless trousers.
- Cover pockets so they will not collect sparks, and remove any flammable materials, such as matches, plastic combs, or gas lighters.
- Wear the proper foot protection. Wear high-top boots with steel toes.
Hot Metal and Burns
Hot metal will cause severe burns. Never handle it with bare hands until it has cooled naturally or has been quenched in the quenching tank. Therefore, use leather gloves with tight fitting cuffs that fit over the sleeves of the jacket. Many welders wear a full set of leathers that consists of the following:
- jacket or set of sleeves
- gauntlet gloves
- leggings
- spats
- apron
- welders hat liner
In gas welding, the high temperatures of the welding flame and the sparks will burn skin. Gas welding can also cause radiation burns due to infrared rays emitted by the red-hot material. Wear flame-resistant or flame-retardant clothing and hair protection at all times.
