Æ Relieve 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 (see sections 2.6
and 2.7.
Æ Verify the lock out.
– Testing the lock out can be done simply by pressing the start button.
Æ The following steps must be taken to restore the machine to operation.
Æ Check the area. Authorized employees should remove all of their tools and reinstall all guards.
Æ 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.
Æ Remove locks/tags Each authorized employee must remove his or her own lock. Each autho-
rized employee will have his or her own lock.
Æ Turn the machine on. Authorized workers should observe the equipment in operation to insure
repairs were done correctly.
2.9.3 Testing
The maintenance or electrical person may test the circuits by energizing the circuit for a short pe-
riod 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.

2.9.5 Training
– Employee training
The safety regulations require training for every individual, of course every employee is not ex-
posed to the same degree of danger or is involved with Lock Out/Tag Out as others are. So
extensive training is not necessary for everyone.
– To determine how much training to provide for each worker, the employees are divided into
three groups. Each group has its own level of training.
– Authorized employees.
These workers actually install the locks and tags and do the preventive maintenance or service
work. So they must know the most about controlled energy. First, they must be able to recog-
nize all energy sources and measure the amount of energy. Authorized employees must look
for energy sources out of the realm of the obvious. These energy sources include electrical,
mechanical, hydraulic, pneumatic, chemical, thermal and gravitational. Once these workers
can recognize all energy sources they must be taught how to isolate, control, and release the
energy without any risk.
– Affected employees
These are workers who operate the machinery or equipment that may be de-energized. Other
employees who may be affected include those who work in an area that contain equipment that
may be locked/tagged out. These employees have to be instructed about the nature of the en-
ergy control program. They must know why lock/tag out is important, what tags and locks look
like and why they must not remove tags or locks.
– All others
As the name implies, any employee who is not affected or authorized fits into this category.
There employees include office personal, managers, and upper management. Although they
do not have a direct relationship to the machinery being locked or tagged, they have to receive
some training.
