LOTO devices are designed to prevent accidental energization during maintenance.

• A. True
• B. False
• C. Sometimes
• D. Never

Answer: (A)

Lockout/Tagout (LOTO) devices are used to isolate energy sources and prevent accidental energization while maintenance or repair work is performed. A lock physically prevents the energy-control device from being operated, and a tag provides a warning that the equipment is locked out and must not be reenergized. This setup ensures a machine remains de-energized until the authorized worker verifies zero energy and removes the lock. Since preventing unexpected startup is the purpose of LOTO during maintenance, the statement is true. It isn’t correct to say it’s only sometimes or never, because the design and practice are specifically to prevent energization during maintenance.
