of the body are highly susceptible to dielectric heating.
The eyes are also highly susceptible to dielectric
heating. Do NOT look directly into devices radiating
rf energy. Remember, rf radiation can be dangerous.
For your own safety, you must NOT stand directly
in the path of rf radiating devices.
PRECAUTIONS WHEN WORKING
As we mentioned earlier, it is extremely important
to follow all safety precautions when working aloft.
Before you work on an antenna, ensure that it is tagged
out properly at the switchboard to prevent it from
becoming operational. Always be sure to secure the
motor safety switches for rotating antennas. Have
the switches tagged and locked open before you begin
working on or near the antenna.
When working near a stack, draw and wear the
recommended oxygen breathing apparatus. Among
other toxic substances, stack gas contains carbon
monoxide. Carbon monoxide is too unstable to build
up to a high concentration in the open, but prolonged
exposure to even small quantities is dangerous.
For more detailed information concerning the
dangers and hazards of rf radiation, refer to the
NAVELEX technical manual, Electromagnetic
Radiation Hazards. NAVELEX 0967-LP-624-6010.
