CHAPTER
Safety
S.1 Introduction
This chapter provides the following safety guidelines for personnel:
•
High Voltage Equipment Operating Guidelines
•
Microwave Radiation Operating Guidelines
•
Physical Safety Guidelines
In addition to the above
items addressed in this chapter, included by reference are the following
pertinent sections of the International Standard EN60215,
Safety Requirements for Radio Transmitting
Equipment
:
•
Appendix D, “Guidance on Assessing the Competence of Personnel for Designation
as Skilled,” and also Sub-clause 3.1 of the Standard.
•
Appendix E, “Guidance on Safety Precautions to be Observed by Personnel
Working on Radio Transmitting Equipment, “and also
Sub-clauses 3.2, 3.7, and 22.1 of the Standard.
S.2 High Voltage Equipment
S.2.1
Personnel Operating Guidelines
This guideline document presents operating practices for operators and technicians who work
with high voltage equipment. In the context of this discussion any voltage that is lethal is viewed
as "high voltage." Therefore, even prime power (100 to 480 V
AC
) is dangerous because prime
power potentials have been known to cause death or injury.
Electrical circuits operate quickly and do not allow a careless individual a second chance. When
dealing with high voltage, the results are very consistent and predictable. The hazards associated
with high voltage are always present.
The fact that the control switch says OFF does not mean
you are safe
. Many high voltage circuits are like loaded guns.
In general, you cannot see a high
voltage hazard
. You can learn to recognize situations that present a threat and how to avoid them.
