2.9 Lock out and tag out procedure
2.9.1 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
2.9.2 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 main switch).
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
Release stored energy
Stored energy in the compressed air supply or electrical energy in electrolytic capacitors must
be released by appropriate means. 2
After switching off the machine, wait the specified discharge or pressure unloading time
(see sections 2.7
, page 100, and 2.8, page 103), before the machine can be operated
again without risk.
Verify the lock out.
Testing the lock out can be done simply by pressing the start button.
The following steps must be taken to restore the machine to operation.
Check the area. Authorized employees should remove all of their tools and reinstall all
guards.
Notify all affected employees.
Before removing even one lock or tag, inform all workers in the area that the machine is going
to be restarted.
Remove locks/tags
Each authorized employee must remove his or her own lock. Each authorized employee will
have his or her own lock.
Turn the machine on. Authorized workers should observe the equipment in operation to in-
sure repairs were done correctly.
2.9.3 Testing
Service personnel may test the circuits by activating them briefly without canceling the locking
method. This may be done only when no other work is being performed by any other person on
the equipment being tested.
It is extremely important that all remote start switches be tagged with the Do Not Operate tag to
prevent inadvertent operation of the equipment during these periods.
