IEEE C95.7-2005 pdf free download – IEEE Recommended Practice for Radio Frequency Safety Programs, 3 kHz to 300 GHz.
1.2 Purpose
These guidelines are provided to assist in the development of RE safety programs for the safe use of RE energy-producing des ices. equipment and systenn, and to present exposures in excess of applicable RE limits for workers or the public The nrans for accomplishing this are by first characterizing areas into one of four espcssure categories according to the potential risk for exposure above prescribed RF exposure limits, as described in 1.3, and then, where relevant, specifying rIse appropriate controls to reduce the likelihood of over•esposure For many situations, this guidance will assist in the development of site- specific Rl safety progranss. while in others the programs may be developed to apply across a wide range of exposure ens ironosents. These guidelines ate designed to complement the ICES TC45 family of standards on electromagnetic sat’ety. but may find mc in the development of effective programs for conformance with other guidelines, standards, or regulations for controlling human exposure to electromagnetic energy. This recommended practice provides guidelines for establishing RE safety progmanss. but other teeonussendatiotss may alteady exist that are deensed sufficient by local regulatory authorities for achieving RI safety in particular environments, Hence, other recommendations could potentially replace or he used in conjunction with the recommendations in this docutssent Guidelines developed for specific applications, for example. radio amateur operations 184F and electneal transmission’distribution personnel working near nsobile phone base -station antennas installed ott electric utility structures (B22J. represent two such examples.
1.3 ApplIcation
The objective of this recommended practice is to provide guidance for the implementation of an RE safety program Such programs are recommended whenever exposures have the potential to eseeed a defined action level or exposure limit talso called the RF safety program initiation level—RFSPIIJ. RFSPILa. or action levels or exposure limits, are typically defined in the applicable safety standard. How’ the levels or limits are defined and controlled is an important pan of an RFSP. For purposes of this recommended practice, the RFSPII, is any of the following eritena (where qplieable):
The lower tier exposure levels of IEEE Std C95. I’
The general public reference levels (lower tier) of the Intemational Commission on Non.loninng
Radiation Protection (ICNIRPI guidelines jBlóJ
-— The general populattossuneontrolled niaxitnumn permissible exposures of the U.S Federal Communications Commission (FCC) 1812]
— One fshlh of the Amenean Conference of Governmental Industrial Hygienists (ACGIH) threshold limit values ITLVs) [82J
The assessment of the RFSPII. includes all applicable atpects of temporal and spatial averaging as specified in the asstsciated standards, guidelines, and regulations. It also includes a consideration of the precedence of fundamental limits Isuch as basic restrictions (FIRs)j over denved limits (such as MPF. levels, investigation levels, and reference levels). For example, devices or systems that have been determined to not he capable of producing exposures that would nosed the FIRs of the relevant exposure limits may need no RE safety program, even though the extemal fields may exceed the RFSPIL Exposure conditions may also consist of the presence of an RE lieU and’w the potential to touch or grasp okeets energized by RE fields.
A practical means for developing an RF safety program is to first categorize the RE sources and systenn according to their potential for producing RE exposure above the RESPIL or exposure limits, and then to specify appropnate controls for each category. IEEE C95.7 pdf download.
