Why is lockout/tagout important during maintenance?

• A. To minimize maintenance time
• B. To prevent unexpected machine startup and protect workers from injury
• C. To reduce fuel consumption
• D. To keep the machine running during maintenance

Answer: (B)

Lockout/tagout is about controlling hazardous energy to keep workers safe while they service equipment. By isolating all energy sources (electrical, hydraulic, pneumatic, mechanical, thermal, etc.) and applying a lock, the machine can’t be energized accidentally. A tag warns that maintenance is in progress and that the equipment should not be operated. This prevents unexpected startups or the release of stored energy, which could cause serious injuries like crush injuries, electrocution, or burns. The process usually involves shutting down the machine, isolating energy sources, locking the controls, tagging to communicate that work is in progress, and testing to confirm there is no energy present before starting repairs. Locks are removed only by the person who applied them, and only when the area is safe. Because of this protective purpose, lockout/tagout directly addresses preventing unintended startup and protecting workers from injury. It isn’t about reducing maintenance time or fuel use, and it certainly isn’t about keeping the machine running during service.
