Purpose and scope
Before performing any preventive maintenance work or service work, a procedure of locking and tagging
must be followed and warning signs must be attached. The procedure, when followed correctly,
eliminates the possibility of an employee being injured.
Description
Whenever it becomes necessary to isolate, control and release energy, the following procedure is to be
followed.
X Notify affected employees.
X Switch off the machine and all additional devices. Carry out all normal stopping procedures:
Press the Stop button.
Shut down the station computer.
Switch the machine off at the main switch.
X Isolate the machine from all its energy sources:
Shut off the compressed air supply
Shut off the main power supply
X Lock out the machine.
Attach a lock whenever possible, e.g. to the motor contactor.
NOTE:
These procedures represent the minimum lock/tag out requirements during preventive
maintenance work and 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.
X Turn the operating lever (1) counterclockwise.
X Use the screwdriver to push the locking lug (2)
out of the operating lever (1).
X Secure the operating lever with a padlock (3).

X Alternative: Attaching warning signs
If a machine can be locked, it must be. However, there are situations where energy isolating 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 or label 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.
X Release of stored energy
Stored energy in the compressed air supply or electrical energy in electrolytic capacitors must be
released by appropriate means.
After switching off the placement machine wait until the voltages and the compressed air have
discharged, to be able work without any risk.
X Testing the lock out.
Testing the lock out can be done simply by pressing the start button.
X The following steps must be taken to restore the machine to operation.
X Check the area. Authorized employees should remove all of their tools and reinstall all guards.
X Notify all affected employees.
X Before removing even one lock or tag, inform all workers in the area that the machine is going to be
restarted.
X Remove locks/tags
X Every authorized employee has to remove his own lock and shut it away.
X Turn the machine on. Authorized workers should observe the equipment in operation to insure
repairs were done correctly.
Testing
Service personnel may test the circuits by energizing the circuit for a short period of time without voiding
the lock out procedure provided. 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.
Responsibilities
It shall be the responsibility of the maintenance and service personnel to make sure this procedure
is adhered to.
It shall be the responsibility of the maintenance and service personnel's immediate supervisor to
instruct his personnel on this procedure.
It shall be the responsibility of the Safety Officer with assistance from the Safety Committee, Health
Service Department, and the various managers and vice-presidents to administer the Lock Out / Tag
Out Procedure.
