Definitions Applicable to Section 1 Through 10 cont'd

DOE-HDBK-1092-2004

Leakage current--Refers to all currents, including capacitively coupled currents, that may be

conveyed between exposed surfaces of the equipment and ground or other exposed surfaces of

the equipment.

Limited access areas--Areas that are kept locked and are accessible only to authorized

personnel because of the hazards they contain.

Modulation--Change in normal characteristics of the recurring pattern in an electromagnetic

field as a result of a secondary electrical signal having been combined with the electrical signal

from which the field originates.

Personnel safety interlock system--One or more of the emergency--shutdown systems or

personnel access control systems or both.

Power density--Emitted power per unit cross--sectional area normal to the direction of

propagation of an electromagnetic wave from which results an electromagnetic field.

Rack cabinet--Any enclosure intended to house electrical equipment mounted to cabinet rails

mounted within the cabinet. Most rack cabinets house chassis 19" wide. They are available in

several heights.

Radio frequency--Non ionizing radiation generated in the portion of the frequency spectrum for

electromagnetic energy between audio and ultraviolet.

Safety barrier--A safeguard installed to restrict personnel access to a hazardous area.

Safety coordinator--An individual who has the responsibility of the safety of the work that is to

be performed and who is familiar with the hazards involved.

Safety interlock--An electrical or mechanical device that prevents operation of equipment or

precludes access to hazardous areas, enclosures, or equipment.

Safety watch--A person whose specific duties are to observe the workers and operations

being performed.

Shall--Information cited is a requirement from a regulatory standard such as OSHA and

relevant DOE Orders.

Should--Information cited is a guidance such as consensus standards.

Underground facility--A facility built below ground surface.

Wavelength--Distance between repetitions of a recurring pattern in an electrical signal or

electromagnetic field.
