appropriate weapon yield, and draw two additional arcs
across the fallout pattern. This is the area where fallout
will be most heavily deposited.
7. When the effective downwind speed is less than
8 KPH (5 knots), the predicted fallout areas of Zone I
and Zone II will be drawn circular around ground zero.
8. Complete the fallout plot by indicating the date-
time
of the message used, the yield and date-time of
burst, ground zero position, and scale of chart used.
Figure 5-8 is an example of a completed fallout plot
using the Ship’s Fallout Template.

PLOTTING CHEMICAL
CONTAMINATION
LEARNING OBJECTIVES: Define terms
associated with chemical warfare. Interpret the
information provided in a NATO chemical
downwind message (CDM). Plot the attack and
hazard area for the three basic chemical
contamination situations.
