What is the purpose of a lockout/tagout procedure?

The purpose of a lockout/tagout procedure is fundamentally aimed at ensuring that machines are properly shut off and cannot be started up again before maintenance or servicing is completed. This process is critical for safeguarding workers who are performing maintenance or repairs on machinery.

When a lockout/tagout procedure is enacted, a lock is physically placed on the machinery to prevent it from being powered on, and a tag is attached to inform others that maintenance is in progress. This not only keeps the machinery in a safe state while workers are addressing issues, but it also significantly reduces the risk of accidental start-up, which could lead to serious injuries.

The focus of lockout/tagout protocols is strictly on worker safety during maintenance tasks, rather than on operational readiness, break schedules, or upgrades. This clear emphasis on safety during potentially hazardous work conditions is why option B is the correct choice.
