Answer 1

Lockout-tagout is a critical safety procedure used to ensure that machines are fully shut off and not prematurely restarted during maintenance. It involves isolating all energy sources, verifying zero energy, and workers applying personal locks for which only they have the keys.

Step-by-step explanation:

The question pertains to a safety procedure known as lockout-tagout (LOTO), which is used to ensure that machines are properly shut off and not started up again before the completion of maintenance or repair work.

For a lockout-tagout to be effective, all the energy sources must be isolated in the 'off' position. It is crucial to verify that there is zero energy, ensuring that no residual energy remains in the system.

Each worker must apply an individual lock to the locking mechanism and retain the key to ensure that only they can remove it once they have completed their portion of the job, thereby preventing accidental re-energization of the machine while work is still ongoing.
