Each authorized person applies his own lock directly to the energy isolation unit.
Must include: lock + information card for each authorizer.
2. Responsible for locking:
The person in charge of the field operation shall open the centralized locking box on the site and lock all the locking points required by HECP (the electrician shall be accompanied to enter the electrical room).
