Simulcast Hardware Installation OSHA Related Safety Requirements
OSHA Related Safety Requirements
The United States Department of Labor, through the provisions of the Occupational Safety and Health
Act (OSHA) of 1970, has established an electromagnetic energy safety standard that applies to the use
of this equipment. Proper use of this equipment will result in exposure below the OSHA limit.
Human Exposure Compliance for RF Energy
STR 3000 Simulcast Base Radios are designed to generate and radiate RF energy by means of
an external antenna. When terminated into a non-radiating RF load, the base radio equipment
is certified to comply with Federal Communications Commission (FCC) regulations pertaining
to human exposure of RF radiation in accordance with the FCC Rules Part 1 section 1.1310 as
published in title 47 code of federal regulations and procedures established in TIA/EIA TSB92, Report
on EME Evaluation for RF Cabinet Emissions Under FCC MPE Guidelines.
Compliance to FCC regulations of the final installation should be assessed and take into account
site specific characteristics, such as type and location of antennas, as well as site accessibility of
occupational personnel (controlled environment) and general public (uncontrolled environment). This
equipment should only be installed and maintained by trained technicians. Licensees of the FCC
using this equipment are responsible for ensuring that its installation and operation comply with FCC
regulations Part 1 section 1.1310 as published in title 47 code of federal regulations.
Whether a given installation meets FCC limits for human exposure to radio frequency radiation
may depend not only on this equipment, but also on whether the “environments” being assessed are
being affected by radio frequency fields from other equipment, the effects of which may add to the
level of exposure. Accordingly, the overall exposure may be affected by radio frequency generating
facilities that exist at the time the licensee’s equipment is being installed or even by equipment
installed later. Therefore, the effect of any such facilities must be considered in site selection and
in determining whether a particular installation meets the FCC requirements.
FCC OET Bulletin 65 provides materials to assist in making determinations if a given facility is
compliant with the human exposure to RF radiation limits. Determining the compliance of transmitter
sites of various complexities may be accomplished by means of computational methods.
In general, observe the following guidelines when working in or around radio transmitter sites:
• Ensure that all personnel have electromagnetic energy awareness training.
• Ensure that all personnel entering the site are authorized.
• Obey all posted signs.
• Assume all antennas are active.
• Beforeworkingonantennas,notifyowners and disable appropriate transmitters.
• Maintain minimum of 1 m (3 ft.) clearance from all antennas.
• Do not stop in front of antennas.
• Use personal RF monitors while working near antennas.
• Never operate transmitters without shields during normal operation.
• Do not operate base station antennas in equipment rooms.
