Which action describes the primary purpose of lockout/tagout devices?

• A. Protect workers from all possible energy sources
• B. Limit noise exposure
• C. Improve comfort
• D. Increase production speed

Answer: (A)

Lockout/tagout is about preventing unexpected energization and the release of hazardous stored energy during maintenance or repair work. The primary aim is to protect workers from injury by ensuring that any energy sources—electrical, mechanical, hydraulic, pneumatic, chemical, or thermal—are isolated and cannot start up or release energy while someone is working on the equipment. A lock physically secures the energy source in a safe position, and a tag serves as a warning that the equipment is not to be operated. Because the lock provides a tangible barrier that only the authorized person can remove, it offers the strongest protection and helps ensure the work can be completed safely before energy is restored. It’s not about reducing noise, increasing comfort, or speeding up production; those are unrelated to the safety purpose of locking and tagging out equipment.
