Why is it important to verify zero energy state during lockout/tagout procedures?

• A. To ensure the machine cannot restart during maintenance
• B. To reduce energy consumption
• C. To speed up maintenance
• D. To improve employee morale

Answer: (A)

Verifying zero energy state is a safety check that confirms all energy sources are isolated and the machine cannot energize during maintenance. This prevents unexpected restart or release of stored energy from springs, hydraulics, capacitors, or other sources, protecting workers from serious injury. It’s not about reducing energy use, speeding up tasks, or boosting morale—its sole purpose is to ensure the lockout truly prevents any energizing of the equipment while someone is working.
