Radiofrequency Program Guidelines-continued

(7) Transmit RF radiation into dummy loads instead of free space radiating,

whenever possible (CECOMR 38517, paragraph 8.a).

(8) When the mission requires free space radiation, do not direct the radiated

beam toward occupied areas where the resulting power density levels in those areas

could equal or exceed the applicable safety standards. "Occupied" areas include mili-

tary and civilian buildings, encampments, elevated structures, etc. (CECOMR 38517,

paragraph 8.b).

(9) For training purposes, operate at the minimum output power level neces-

sary to perform the training mission (CECOMR 38517, paragraph 8.i).

(10) When the mission requires operating near occupied areas, keep poten-

tially hazardous radiated beams at a safe distance from these areas through the use of

interlocks, antenna sector blanking, fences, or other positive means (CECOMR

38517, paragraph 8.c).

(11) Inspect interlocks, antenna sector blanking systems, and other beam re-

striction devices periodically. Keep a permanent record of these inspections on file for

reference (CECOMR 38517, paragraph 8.d).

(12) Only authorized personnel may set up, adjust, or operate RF systems.

Prohibit the use of these systems by unnecessary or unauthorized personnel for peri-

ods of time beyond that which are absolutely necessary (CECOMR 38517, para-

graph 8.e).

(13) Exclude personnel from the beam path at all points where the power

density level of the beam could potentially exceed the safety standard. Keep the poten-

tially hazardous beam path under surveillance to ensure it remains clear of personnel

(CECOMR 38517, paragraph 8.f).

(14) Prepare signs IAW ANSI C95.21982, 5 August 1981.

(15) Post signs to indicate the nature of the RF hazard. (DoDI 6055.11, enclo-

sure 5, paragraph 3.; ANSI C95.21982, 5 August 1981). Figure 1, below, is an exam-

ple of a typical RF hazard posting.

(16) Post signs where warning lights are employed to inform personnel that

the lights, when energized, are an indication that a potential health hazard is present,

and when interlocks have been overridden (CECOMR 38517, paragraph 8.h). Main-

tain an operational log for each piece of equipment to annotate overrides/bypasses (AR

405, paragraph 99.a.(2)(b)5).

(17) With the transmitter disabled, periodically inspect potentially hazardous

waveguides, especially flexible waveguides. Look for cracks in the waveguides. Ensure
