What are the key components of a lockout/tagout program in mining?

• A. Energy isolation, lockout devices, tags to indicate de-energization, training, and verification.
• B. Only labeling without isolation.
• C. Rely on supervisor's memory for de-energization.
• D. Lockout is only for electrical systems.

Answer: (B)

Lockout/tagout programs are designed to prevent injury from unexpected machine startup or release of stored energy while work is being done. The essential elements involve isolating all energy sources so the equipment cannot re-energize, using lockout devices to physically secure those isolation points, applying tags to communicate that de-energization has occurred and who is responsible, providing training for those performing the lockout as well as anyone affected, and verifying that the isolation is effective before work begins and after it’s complete. In mining, this means addressing electrical, mechanical, hydraulic, pneumatic, gravity‑driven, and stored energy, with clear procedures for how to isolate, lock, tag, test, and release energy. Labeling alone does not stop energization, relying on a supervisor’s memory is unsafe, and lockout/tagout protects more than just electrical systems.
