What safety equipment should you wear when performing mechanical work with potentially energized circuits?

• A. Safety glasses, gloves, hearing protection as needed; lockout/tagout procedures; insulated tools; proper footwear
• B. Only safety glasses
• C. No PPE required for energized circuits
• D. A dust mask and gloves

Answer: (A)

Protection against electrical hazards through proper PPE and procedures is essential whenever there’s a chance of energized circuits. Eye protection shields you from arcs, sparks, and flying debris that can occur during mechanical work near live components. Insulated gloves guard the hands against shock and burns, while hearing protection may be needed if there’s loud equipment or arcing sounds. Lockout/tagout procedures ensure the circuit is de-energized and cannot be re-energized during the work, a fundamental step to prevent unexpected energization. Insulated tools further reduce the chance of conducting electricity through the tool, and proper footwear helps protect feet and provides insulation from shock hazards. These measures work together to create multiple layers of safety rather than relying on a single precaution.

Other options fall short because they leave critical risks unaddressed: safety glasses alone don’t protect hands or feet; no PPE at all ignores the hazard of shock and arc flash; a dust mask and gloves don’t address electrical safety and arc hazards.
