The electrical safety program hazard evaluation procedures must be used before any work on or near live parts operating at how many volts or more?

• A. 25
• B. 50
• C. 100
• D. 120

Answer: (B)

Before performing any work on or near live electrical parts, you need to identify and control the hazards you’ll face. The threshold used for this hazard evaluation is 50 volts or more, in either AC or DC. When live parts operate at 50 volts or higher, a documented hazard analysis within the electrical safety program must be conducted to determine appropriate protective measures, such as de-energizing the circuit if feasible, applying lockout/tagout, establishing safe work boundaries, and selecting suitable PPE. This helps ensure shocks and arc flash risks are properly addressed before work begins. Voltages below 50 volts generally don’t require this formal hazard evaluation under the standard, though basic safety considerations still apply.
