This standard defines the design of symbols denoting the incidence of radio-frequency (RF) electromagnetic energy in the frequency range from 3 kHz to 300 GHz. The standard also defines the use of these symbols in signs and labels intended to warn workers and the public of the presence of potentially hazardous levels of RF energy and other hazards that may arise from RF energy, such as RF induced currents, shocks, or burns. Guidance on the application and placement of these signs in operational settings is not within the scope of this document.
Symbols to inform people about the presence of potentially hazardous levels of radio-frequency energy or the presence of contact current hazards in the frequency range of 3 kHz to300 GHz are specified. Guidance is given about how these symbols should be used on warning signs and labels.

Elements of a radio frequency (RF) exposure safety program that can prevent or control potential risks associated with exposure to the electromagnetic fields from RF sources that operate in the frequency range of 3kHz to 300 GHz are described in this recommended practice. The means for accomplishing this are classifying exposure locations into one of four categories based on the potential hazard, as defined by exposure limits, and specifying appropriate controls for each category. Such controls include engineering and administrative controls as well as the use of personal protective equipment, placement of appropriate RF safety signage, designation of restricted access areas, the use of personal RF monitors, and RF safety awareness training. These recommendations are not intended to apply to the purposeful exposure of patients by or under the direction of medical practitioners, but can be used in the development of safety programs for medical staff and other persons working with or incidentally exposed to RF fields, and for those wearing implanted or external medical electronic devices. Although designed to complement IEEE Std C95.1, this recommended practice may also be used for the development of programs to insure conformance with IEEE Std C95.6 and with other guidelines, standards, or regulations for controlling human exposure to electromagnetic energy.
