According to OSHA, why do welders face a higher-than-normal risk of electric shock?

• A. They often work outside and therefore have an increased chance of being struck by lightning
• B. Most of a welder's equipment is electrically energized
• C. They are likely to be found on jobsites where exposed, live wires are common
• D. They don't wear PPE specifically designed to prevent electric shock

Answer: (B)

The main idea is that welding involves equipment that is energized by a power source. In this setup, the electrode holder, welding cables, and work clamp carry live current, and the arc itself provides a conductive path. If a welder touches a live part and a grounded object (or if insulation is damaged or the area is wet), current can flow through the body, causing an electric shock. This constant presence of energized equipment is what OSHA highlights as increasing the shock risk for welders. While outdoor work, exposed live wires, or PPE gaps can contribute to hazards, the core reason is the energized nature of the welding apparatus. PPE helps mitigate harm but cannot eliminate the electrical hazard inherent in a live welding circuit.
