Purpose and scope
Before performing any preventive maintenance work, conversion work or service work, a procedure
of locking and tagging must be followed and warning signs must be attached if not stated other-
wise. If you do not need to switch off the machine, this will be clearly stated.
The procedure, when followed correctly, eliminates the possibility of an employee being injured.
NOTICE
Additional safety measures
This procedure represents the minimum lock out and tag out requirements for the machine
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.
Description
Whenever it becomes necessary to isolate, control and release energy, the following procedure is
to be followed.
► Notify all affected employees.
► Switch off the machine and all additional devices. Carry out all normal stopping procedures:
ð Press the STOP button.
ð Shut down the station computer.
ð Switch off the machine using the main switch.
► Isolate the machine from all its energy sources:
ð Shut off the compressed air supply.
ð Shut off the main power supply.
► Lock out the machine.

► Alternatively, you can attach warning signs:
Any machine that can be locked must be locked.
However, there are situations where energy isolating devices cannot accommodate locks. In
these cases, the energy isolating devices must be tagged appropriately to warn employees
that the machine is currently de-energized for service purposes. The tag or label must be
fastened securely in a position visible from all sides and it may only be removed by the person
who attached it.

► Release of stored energy:
Energy stored as compressed air in the compressed air supply or electrical energy stored in
electrolytic capacitors must be released by appropriate means.
After switching off the machine, wait until the voltages have discharged and the compressed
air has released, so that work can be performed without any risk.
DANGER
Checking for absence of voltage!
► Before you start working, check the power supply for absence of voltage and observe
the waiting times!
► Testing the lock out:
The lock can be easily tested by pressing the START button.
The following steps must be taken to restore the machine to operation.
► Check the workspace. Authorized employees should remove all of their tools and reinstall all
safety features.
► Notify all affected employees.
► Before removing even one lock or tag, inform all workers in the affected area that the machine
is going to be restarted.
► Remove all locks/tags.
Every authorized employee must remove his own lock and shut it away.
► Switch the machine on. Make sure that authorized staff check the equipment in operation to
ensure that all repairs were performed correctly.
Testing
Service personnel may test circuits by energizing them briefly without suspending the lock out / tag
out procedure. This may only be done 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 are 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 pro-
cedure is adhered to.
●
It shall be the responsibility of the maintenance and service personnel's immediate supervisor
to instruct their personnel on this procedure.
●
It shall be the responsibility of the Safety Officer to administer the lock out / tag out procedure.
