manner that allows rf current to flow through the area of contact. Resistance of the skin to the current
flow at the areas of contact causes heat. The effect of the heat on a person at the point of contact ranges
from noticeable warmth to a painful burn.
The most useful and widespread technique in the reduction of rf burn hazards is the proper bonding
and grounding of all metallic objects in the rf radiation field.
In some cases, the rf burn hazard can be eliminated only through the use of restrictive operating
procedures. These procedures govern the simultaneous use of transmitting and cargo equipment.
Techniques such as operation of transmitters at reduced power and the prohibition of simultaneous use of
certain combinations of antennas, frequencies, and cargo handling equipment are used.
Figure 3-35 shows typical rf radiation hazard warning signs.
