6. RF Guidelines
To ensure safety of company workers, the following points need to be taken into
consideration and implemented at wireless sites in accordance with the Carriers
policies:
a) Worksite: Any employee at the site should avoid working directly in front of
the antenna or in areas predicted to exceed general population exposure
limits by 100%. Workers should insist that the transmitters be switched off
during the work period.
b) RF Safety Training and Awareness: All employees working in areas
exceeding the general population limits should have a basic awareness of
RF safety measures. Videos, classroom lectures and online courses are all
appropriate training methods on these topics.
c) Site Access: Restricting access to transmitting antenna locations is one of the
most important elements of RF safety. This can be done with:
• Locked doors/gates/ladder access
• Alarmed doors
• Restrictive barriers
d) Three-foot Buffer: There is an inverse relationship between the strength of
the field and the distance from the antenna. The RF field diminishes with
distance from the antenna. Workers should maintain a three-foot distance
from the antennas.
e) Antennas: Workers should always assume that the antenna is transmitting
and should never stop right in front of the antenna. If someone must pass by
an antenna, he/she should move quickly, thus reducing RF exposure.

9. Appendix A: FCC Guidelines
FCC Policies
The Federal Communications Commission (FCC) in 1996 implemented regulations
and policies for analysis of RF propagation to evaluate RF emissions. All the analysis
and results of this report are compared with FCC’s (Federal Communications
Commission) rules to determine whether a site is compliant for
Occupational/Controlled or General Public/Uncontrolled exposure. All the analysis
of RF propagation is done in terms of a percentage. The limits primarily indicate
the power density and are generally expressed in terms of milliwatts per
centimeter square, mW/cm2.
FCC guidelines incorporate two separate tiers of exposure limits that are
dependent on the scenario/ situation in which that exposure takes place or the
status of the individuals who are subjected to that exposure. The decision as to
which tier is applied to a scenario is based on the following definitions:
Occupational / Controlled
These limits apply in situations when someone is exposed to RF energy through
his/her occupation, is fully aware of the harmful effects of the RF exposure and has
an ability to exercise control over this exposure. Occupational / controlled
exposure limits also apply when exposure is of a transient nature as a result of
incidental passage through a location where exposure levels may be above
general population/uncontrolled limits (see below), as long as the exposed person
has been made fully aware of the potential for exposure and can exercise control
over his or her exposure by leaving the area or by some other appropriate means.
limits for Occupational/Controlled exposure can be found on Table 1(A).
General Population / Uncontrolled
These limits apply to situations in which the general public may be exposed or in
which persons who are exposed because of their employment may not be made
fully aware of the potential for exposure or cannot exercise control over their
exposure to RF. Therefore, members of the general public would always be
considered under this category, for example, in the case of a telecommunications
tower that exposes people in a nearby residential area. Exposure limits for General
Population/Uncontrolled can be found on Table 1(B).

OSHA Statement:
The objective of the OSHA Act is to ensure the safety and health of the working
men and women by enforcing certain standards. The act also assists and
encourages the states in their efforts to ensure safe and healthy working conditions
through means of research, information, education and training in the field of
occupational safety and health and for other purposes.
According to OSHA Act section 5, important duties to be considered are:
(a) Each employer
1) Shall furnish to each of his employees’ employment and a
place of employment which are free from recognized
hazards that are causing or are likely to cause death or
serious harm to his employees
2) Shall comply with occupational safety and health standards
promulgated under this act.
(b) Each employee shall comply with occupational safety and health standards
and all rules, regulations, and orders issued pursuant to this Act which are
applicable to his own actions and conduct.
