What is the purpose of lockout/tagout (LOTO) procedures?

• A. To prevent unexpected machine energization during maintenance or repair.
• B. To track inventory
• C. To monitor productivity
• D. To train new hires

Answer: (A)

Lockout/tagout procedures are designed to prevent unexpected machine energization during maintenance or repair. By identifying all energy sources, isolating them, applying a lock or tag to prove the equipment cannot be energized, and verifying zero-energy conditions before work begins, workers are protected from startup or the release of stored energy that could cause serious injury. The lock physically restricts re-energizing, and the tag warns that maintenance is in progress, ensuring only authorized personnel can remove the device after safety checks. This safety control is specifically about energy management during servicing, not about inventory tracking, productivity monitoring, or training new hires.
