In the event service will continue into another day, and/or the machine will cause a
hazard if reenergized after the authorized employee leaves the location, leave the A/C
cord cover installed with a “transition” lock and yellow tag attached.

same time, multiple locking devices must be employed and each authorized employee
must adhere to the entire LOTO procedure.
