Before performing any maintenance work or service work, a procedure of locking and tagging
must be followed. The procedure, when followed correctly eliminates the possibility of an
employee being injured.
NOTE
These procedures represent the minimum lock / tag out requirements.
Any additional safe - guards needed to complete work safely can be specified by supervision fa-
cilities, the safety officer, the safety committee and the health department.

– Alternatively: Attach warning signs
If a machine can be locked, it must be locked. However, there are situations where in order to
release energy locks cannot be used. In these cases, these machines must be tagged with warn-
ing signs in order to warn employees that the machine is energized for servicing. The tag must be
securely fastened, it must be placed in a position visible to all and it may only be removed by the
person who attached it.
1. Turn the operating lever (1) counter-clockwise.
2. Use the screwdriver to push the locking lug (2) out of the operating lever (1).
3. Secure the operating lever with a padlock (3).
