The soldier placing the sign puts an arrow or other directional symbol
in the center of the sign to indicate the direction of the
contaminated area. Two such directional symbols with a number to the
right indicate the width of the passage. The white rectangle on the
left of the sign indicates the type of contamination. The bottom of
the sign carries the notation 4EPE3 (across, over, or through)
followed by a number indicating the distance through the contaminated
area.
If troops cannot decontaminate a passage through the area, they
reconnoiter a passage or detour around the area and mark it with
warning signs. They place a directional arrow and 06BE3A (detour) on
the sign, and they cross out 4EPE3 (Figure 3-11).

Indicating a Detour Around a Contaminated Area
The standard triangular flags consist of red or yellow cloth mounted
on metal poles. These flags indicate three levels of radiation:
One yellow flag indicates a radiation level of more than 0.1
cGy/hr.
One red flag indicates a radiation level of more than 5
cGy/hr.
One yellow flag and one red flag indicates a radiation level
of more than 100 cGy/hr.
Personnel place the flags or markers for a given level of
contamination 20 to 25 meters apart at each of the three radiation-
level boundaries.
