WHAT IS THE FCC’S POLICY ON RADIOFREQUENCY WARNING SIGNS? FOR EXAMPLE, WHEN SHOULD SIGNS BE POSTED, WHERE SHOULD THEY BE LOCATED AND WHAT SHOULD THEY SAY?

Radiofrequency warning or alerting signs should be used to provide information on the presence of RF radiation or to control exposure to RF radiation within a given area.  Standard radiofrequency hazard warning signs are commercially available from several vendors.  Appropriate signs should incorporate the format recommended by the Institute for Electrical and Electronics Engineers (IEEE) and as specified in the IEEE standard: IEEE Std C95.2-1999 (Web address: http://www.ieee.orgOpens a New Window.).  Guidance concerning the placement of signs can be found in the IEEE Standard: IEEE Std C95.7-2005 (available for free through the IEEE Get Program).  When signs are used, meaningful information should be placed on the sign advising affected persons of:  (1) the nature of the potential hazard (i.e., high RF fields), (2) how to avoid the potential hazard, and (3) whom to contact for additional information.  In some cases, it may be appropriate to also provide instructions to direct individuals as to how to work safely in the RF environment of concern.  Signs should be located prominently in areas that will be readily seen by those persons who may have access to an area where high RF fields are present.
