What is the main purpose of a lockout/tagout procedure?

The main purpose of a lockout/tagout procedure is to prevent the operation of equipment during maintenance activities. This procedure ensures that machinery is properly shut down, and any energy sources, such as electricity, hydraulics, or pneumatics, are controlled to prevent accidental startup. By implementing lockout/tagout, workers can perform repairs or maintenance safely without the risk of equipment being turned on unexpectedly. This practice is crucial for minimizing accidents in industrial settings, thereby protecting the health and safety of employees.

Other options, such as allowing continuous operation or enhancing electrical efficiency, do not align with the fundamental goal of lockout/tagout, which is to ensure that equipment remains in a non-operational state during maintenance tasks. Preventing unauthorized access is not the primary focus of this procedure, as it specifically addresses safe work practices related to energy control rather than security measures.
