One of the conditions where energized conductors and circuit parts operating at voltages equal to or greater than 50 volts shall be put into an electrically safe work condition before an employee performs work where the employee is within the ? boundary.

• A. Restricted Approach
• B. Limited Approach
• C. Proximity Boundary
• D. Safe zone

Answer: (B)

When a worker will be within a defined distance of energized parts, energy must be controlled before work begins. Specifically, if the conductors or parts are energized at 50 volts or more and the employee is within the limited approach boundary, the equipment must be placed in an electrically safe work condition. This means de-energizing the circuit, applying lockout/tagout, discharging stored energy, and verifying zero energy with proper testing before performing the work. Entering the limited boundary while energy could still be present would risk shock or arc flash, so establishing a safe condition removes that energy hazard. The other terms aren’t the standard boundary related to this requirement.
