When a reasonable possibility exists of contacting electrical lines during excavation, what shall be used?

• A. Only safe work practices
• B. Appropriate safe work practices and PPE
• C. PPE only
• D. No special precautions

Answer: (B)

When digging near electrical lines, you must combine planning with personal protection. Safe work practices cover the steps that prevent contact in the first place: locating and marking underground utilities, establishing exclusion zones, choosing the right excavation methods (such as hand digging near identified lines), and following procedures that keep workers and equipment away from the hazard. PPE adds the personal protection component in case contact or exposure occurs: insulating gloves, dielectric footwear if needed, a hard hat with face shield, eye protection, and appropriate flame-resistant clothing based on the voltage and task. Relying on just PPE or just practices leaves gaps—either the lines aren’t adequately isolated or the worker isn’t protected if contact occurs. Using both together provides the necessary layered protection.
