late, control, and release the energy without any risk.
4. 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/tag out is important, what tags and locks look like and why they must not remove tags
or locks.
5. All others.
As the name implies, any employee who is not affected or authorized fits into this category. There employ-
ees include office personal, engineers, 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.
6. To evaluate the lock/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 LO/TO procedure.
1.6.6 Review
This procedure will be reviewed and amended as required but in no case less frequently than once a year.
1.6.7 Appendix
These procedures represent the minimum lock/tag out requirements. Any additional safeguards needed to
complete work safely can be specified by facilities supervision, the safety officer, the safety committee and the
health department.

1.7.1 X-ray radiation
The X-ray radiation generated in the monitor is adequately shielded by the intrinsically safe cathode-ray tube.
The local emissions are less than 1 µS/h (micro-Sievert per hour). The accelerating voltage is limited by the
device to a maximum of 26 kV.
The monitor conforms to the German Directive for protection against harmful X-ray radiation. The X-ray emis-
sions from the monitor conformed to the DHHS Rules 21 CFR, subsection J on the date of manufacture and
to the FCC Rules, part 15.
1.7.2 Efficiency and electromagnetic emissions
The MCM 1405 ND monitor fulfils the conditions for efficiency (to ISO 9241-3) and safety (to EN 60950).
The low-frequency electromagnetic emissions fall below the MPR II guidelines issued by the Swedish Radia-
tion Institute in Stockholm.

1.8.1 What does ESD mean?
Almost all of the modules in use today are equipped with highly integrated MOS blocks and components. The
manufacturing techniques used mean that these electronic components are extremely sensitive to overvolt-
age and thus to electrostatic discharge.
The abbreviation for such modules is ’ESD’ (E
lectrostatic Sensitive Device). This is used internationally,
although the German abbreviation ‘EGB‘ may also be seen.
The following symbol on cabinet rating plates, racks or packaging indicates that components which are sensi-
tive to electrostatic discharge have been used and thus that the modules concerned are also touch-sensitive.
ESDs can be destroyed by voltages and power levels that are far below the level that can be
perceived by humans. Such voltages occur if a person touches a component or module without
earthing themselves. Components that are exposed to such overvoltages do not generally
appear to be defective immediately - incorrect behavior starts after the component or module
has been in operation for some time.
1.8.2 Important measures to protect against static charging
● Most plastics can easily become charged and must therefore be kept away from at-risk components.
● Always ensure that people, the workplace and packaging are safely earthed when handling electrostatic
sensitive components.
1.8.3 Handling ESD modules
Do not touch electronic modules unless it is absolutely essential to do so in order to carry out other work. If it
is necessary, make sure that you do not touch the pins or printed conductors when you pick up flat modules.
Do not touch components unless
● you are constantly earthed by an ESD wrist strap or
● you are wearing ESD shoes or ESD shoe earthing strips on an ESD floor.
Always discharge yourself before you touch an electronic module. To do this, simply touch a conductive and
earthed object immediately before you touch the module (such as unpainted parts of a switch cabinet, a water
pipe, etc.).
Do not allow modules with chargeable and highly insulating materials to touch one another, e.g. plastic films,
insulating table surfaces or items of clothing made from synthetic fibers.
