What PPE is recommended when performing electrical diagnostics on a bus?

• A. Use appropriate PPE such as safety glasses and insulated gloves when working on live circuits.
• B. PPE is optional.
• C. Only gloves are required.
• D. PPE is only for non-electrical tasks.

Answer: (C)

Electrical diagnostics on a bus involve shocks and arc-flash risks, so using proper PPE is essential. The best practice is to wear safety glasses and insulated (dielectric) gloves whenever you’re working on or near live circuits. Eye protection guards against sparks, debris, and accidental splashes, while insulated gloves reduce the chance of electric shock when handling energized components. Depending on the voltage and specific task, you may also need arc-rated clothing, a face shield, and appropriate footwear. PPE isn’t optional, and relying on gloves alone doesn’t protect other exposed areas like eyes and face. PPE is required for electrical work to reduce multiple hazard types, not just for non-electrical tasks.
