From software version SC.706.xx Version 06/2012 EN 2.11 Lock out and tag out procedure
89
2.10.3 Compressed air conditions in the machine after switching off at the main
power switch
When you switch off the main switch (item 1 in fig. 2.10 - 1, page 85) or if the power supply to the
machine fails, the electrically controlled main valve of the compressed air unit (item 1 in fig. 2.9 -
1, page 84 ). The pressure will drop to 0 MPa (0 bar) within 5 seconds.
2.11 Lock out and tag out procedure
2.11.1 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.
PLEASE NOTE These procedures represent the minimum lock/tag out requirements for the pre-
ventive 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. 2
2.11.2 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).
