1.1.5 Safety Instructions for the Gantry
When moving the gantry, observe the following:
1.1.6 Safety Instructions on Hazardous Materials
CAUTION
Observe the applicable safety data sheet, when handling hazardous materials (e. g.
1.1.7 Classification of the Optical Systems
1.1.7.1 Classification of the Camera Systems
The camera illumination systems are fitted with light LEDs. These are assigned to risk
group 1 according to IEC 62741:2006.
1.2 Lock out and tag out procedure
1.2.1 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
otherwise. If it is not necessary to switch off the machine, it is explicitly mentioned.
The procedure, when followed correctly, eliminates the possibility of an employee being injured.
NOTICE
These procedures represent the minimum lock/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
1.2.2 Description
Whenever it becomes necessary to isolate, control and release energy, the following procedure is
to be followed.
► Notify affected employees.

► 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.
► Isolate the machine from all its energy sources:
● Shut off the main power supply.
► Lock out the machine.
● Attach a lock wherever possible (e.g. to the main power switch or the motor contactor).
If a 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
devices must be tagged to warn employees that the machine is de-energized for
servicing. The tag must be securely fastened, it must be placed in a position visible to all
► Release stored energy:
Stored energy in the electrical energy in electrolytic capacitors must be released by appropriate
means.
● After switching off the machine, wait the specified discharge time (see sections 1.1.4Residual
voltages and discharge times in the machine and 1.2Lock out and tag out procedure), before
the machine can be operated again without risk.
► Verify the lock out:
Testing the lock out can be done simply pressing the start button.
► The following steps must be taken to restore the 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 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 machine on. Authorized workers should observe the equipment in operation to ensure
repairs were done correctly.

1.2.3 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.

1.2.4 Responsibility and obligations
– 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.
1.2.5 Training
– Staff training:
● The safety regulations require training for every individual. Of course, not every employee is
exposed 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
recognize 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
energy control program. They must know why lock out/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.
These 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.
● To evaluate the lock out/tag out procedure, the safety department will conduct periodic
inspections. As part of the inspection the safety department will document that all facets of the
procedure are followed. The safety department will follow up with formal classroom review or
retraining of the lock out/tag out procedure.
1.2.6 Review
This procedure will be reviewed and amended as required, and at least once a year.
