Which statement best reflects a core electrical safety practice?

• A. Only training is required; other measures are not necessary.
• B. Electrical safety is unrelated to equipment maintenance.
• C. Only installed signage is sufficient.
• D. Lockout-tagout and maintenance are key components of electrical safety.

Answer: (D)

Controlling energy sources through lockout-tagout and performing proper maintenance is essential for electrical safety. Lockout-tagout stops unexpected energization by physically isolating energy sources and tagging the status and who is working, so others cannot re-energize the equipment. Verifying zero energy before starting work is a critical step. Maintenance matters because it keeps safety devices and electrical components in good working order, reducing the chance of faults that could energize unexpectedly. Training and signage are helpful, but without a formal LOTO process, equipment can be energized by mistake or via stored energy. Therefore, integrating lockout-tagout with routine maintenance and energy-control procedures offers the most reliable protection.
