The shock protection approach boundary distances are the distances from exposed energized electrical conductors or circuit parts to the employee.

• A. True
• B. False
• C. They are measured to the equipment
• D. They depend on weather

Answer: (A)

Shock protection boundary distances are defined by how far the exposed energized conductors or circuit parts are from the worker, not from the equipment. This reference to the employee ensures the boundary corresponds to the actual risk to the person and guides the required PPE and safe work practices. Measuring to the employee is what determines whether a worker is in a safe zone or needs additional protection. Weather is not used to adjust these distances; they are based on voltage and the protective equipment category, independent of environmental conditions.
