2.9 Locking and attaching the warning labels
2.9.1 Purpose and scope
Before performing any preventive maintenance work or service work to the placement machine,
a procedure of locking and tagging must be followed. The following procedure, when followed cor-
rectly, eliminates the possibility of an employee being injured by electrical shock in connection with
unexpected movement.

2.9.2 Description
Whenever it becomes necessary to isolate, control and release energy for the placement ma-
chine, the following procedure is to be followed.
Notify affected employees.
Switch off the placement machine and any auxiliary devices. Carry out all normal stopping
procedures:
– Press the stop button.
– Shut down the control computer.
– Switch the placement machine off at the main power switch.
Isolate the placement machine from all its energy sources:
– Shut off the compressed air supply
– Shut off the mains 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 on the placement machine. Any additional safeguards
needed to complete work safely can be specified by facilities supervision, the safety of-
ficer, the safety committee and the health department.

Alternatively: Tag out procedure
If the placement machine can be locked out, it must be. However, there are situations where
energy isolating devices cannot accommodate locks. In these cases, the energy isolating de-
vices must be tagged to warn employees that the placement machine is de-energized for ser-
vicing. 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 placement machine, wait the specified discharge or pressure un-
loading time (see sections 2.7
, page 84, and 2.8, page 87), before the placement ma-
chine can be operated again without risk.
Verify the lock out.
Testing the lock out for the placement machine can be done simply by pressing the start but-
ton.
The following steps must be taken to restore the placement 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 placement
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 placement machine on. Authorized workers should observe the equipment in
operation to insure 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.
