Stud welding systems used in accordance with the National Electrical Code NFPA-70 and local codes should pose no threat to trained professionals. However, steps can be taken to further reduce safety hazards.
Electrical precautions for a safe arc welding environment
- Schedule regular inspections and maintenance of welding equipment to identify and correct insulation breakdown, frayed wiring, or other damages that pose a threat to welders.
- Equip welders with appropriate PPE, such as rubber-soled safety boots and insulated gloves, to reduce risk of injury.
- Establish proper grounding to prevent stray currents that could threaten the welder as well as others in the weld zone.
- Turn off power when not in use or when handling the material being welded.
- Work in wet areas or weld when you or your PPE are wet.
- Touch live electrical parts as it could establish a current path through your body.
Fire precautions for a safe arc welding environment
- Remove all flammable materials from the work station.
- Take extra precautions when it is necessary to weld near or through combustible materials to prevent sparks or berries from reaching and igniting them.
- Properly store gas cylinders away from the workstation to prevent ignition.
- Keep fire suppression equipment on hand for easy access and train welders to properly use it.
- Be aware of emergency exits in case of fire.
- Handle welded parts without gloves until they have had ample time to cool.
- Degrease or use flammable solvents near welding stations.
PPE precautions for a safe arc welding environment
- Wear eye protection at all times when welding in accordance with ANSI Standard Z87.1.
- Wear ear protection when operating or working within a confined environment wherein noise levels are considered hazardous. More information can be found in OSHA Standard 29, CFR, Part 1910, Sub-part Q, Welding, Cutting, and Brazing.
- Wear flame-resistant clothing, including high boots, gloves, apron, leather leggings, etc. to protect skin from splatter, arc flash, sparks, and berries. See ANSI/ASC Z49.1, Safety in Welding and Cutting for more detailed information.
- Wear a welding helmet or goggles to prevent burns and other damage caused by intense heat and light.
- Wear respirators to protect lungs from harmful fumes.
- Wear flammable synthetic fabrics.
Other precautions for a safe arc welding environment
- Handle materials carefully to prevent cuts from sharp metal edges.
- Use proper lifting techniques to avoid injury when lifting heavy materials.
- Reduce trips and falls by diminishing loose cabling on the floor and noting hazards where they remain through signage.
- Avoid arc stud welding if you have been fitted with a heart pacemaker as the high currents can create elevated magnetic fields.
