What is the primary purpose of a lockout/tagout (LOTO) program?

• A. To prevent unexpected energization or startup of equipment during maintenance and protect workers from injury.
• B. To identify hazards during operation.
• C. To lock doors in maintenance areas.
• D. To tag out only when replacing components.

Answer: (A)

Lockout/tagout programs focus on controlling hazardous energy so equipment cannot energize or start up unexpectedly while someone is working on it. This means identifying all energy sources, isolating them, applying locking devices and warning tags, verifying that the equipment is in a zero-energy state, and only then performing maintenance. After the work is done, the energy is safely released and locks are removed so the machine can be reenergized. This approach specifically targets preventing injuries from unexpected energization, which is why it’s broader and more precise than simply identifying hazards during operation or general access controls. Tagging out without the locking part or using LOTO only for component replacement does not provide the same level of protection, since the equipment could still be energized or re-energized by someone else.
