2.10 Lock out and tag out procedure
2.10.1 Purpose and scope
Before performing any preventive 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.
2
2.10.2 Description
Whenever it becomes necessary to isolate, control and release energy, the following procedure is
to be followed
Notify affected employees.
Shut down the equipment. Carry out all normal stopping procedures:
– Press the stop button.
– Shut down the control computer.
– Switch the machine off at the main power switch.
Isolate the machine from all its energy sources:
– Shut off the compressed air supply
– Shut off the main power supply
Lock out the machine.
– Attach a lock whenever possible (e.g. to the motor contactor).
PLEASE NOTE
Minimum requirements
These procedures represent the minimum lock/tag out requirements for the preventive
maintenance or service work. Any additional safeguards needed to complete work safely
can be specified by facilities supervision, the safety officer, the safety committee and the
health department.

Alternatively: tag out procedure
If a machine can be locked out, it must be. However, there are situations where energy iso-
lating devices cannot accommodate locks. In these cases, the energy isolating devices must
be tagged to warn employees that the machine is de-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. 2
