When electric equipment is derailed, how must it be treated?

• A. Energized
• B. De-energized
• C. Grounded
• D. Isolated

Answer: (A)

Treat it as energized. After a derailment, electric equipment can still be live or capable of re-energizing, so the safe approach is to assume it is energized and keep people clear until authorized personnel verify de-energization and perform proper lockout/tagout procedures. Only then can the system be isolated or grounded as part of safe work. Ending with de-energizing or isolating without first confirming energy status would be unsafe; grounding or isolation are actions that follow a confirmed energy shutdown by qualified staff.
