PART A - NBC CONTAMINATION MARKERS
1.
Contamination Markers.
Because of the potential effects posed by chemical or biological agents
on personnel, markers have been devised to identify areas contaminated by
these agents or areas which contain chemical mines. When a contaminated
area has been identified, its boundaries are marked with contamination
markers.
Signs used for marking contaminated areas are standard throughout North
Atlantic Treaty Organization (NATO).
A NATO marker is a right-angled
isosceles triangle.
The base is approximately 28 centimeters (11 1/2
inches) and the sides are 20 centimeters (8 inches). It has holes used
for hanging.
It may be placed on boundary fences, poles, trees, or
rocks. Place a sign with the point of the triangle facing down.
The United States marks contaminated areas with the NBC Contamination
Marking Set.
It contains everything needed to mark an area - flags,
ribbon, crayons, mounting stakes, and a carrying container. TM 3-9905-
001-10 describes the kit and its use.
A NATO NBC Marking Set is
available and bears the stock number NSN 9905-12-124-5995. If units do
not have the kit available, they can make the signs out of available
metal, plastic, or wood. These field expedient signs must be of standard
shapes, sizes, and colors.
Areas which are found to be contaminated with more than one type of
contamination will be marked with markers of each type of contamination.
The color and size permits easy identification. The color indicates the
type of contamination.
The primary or background color indicates the
general hazard. The secondary color gives hazard specifics. Identified
contaminated areas are marked unless they are to be abandoned to Threat
Forces. Information concerning the contamination is printed on the front
of the marker as shown in Figure 1-1.
When placing contamination markers in position, the markers should be
placed at short intervals around the contaminated area. Markers should
be prominently displayed on roads or paths leading into the contaminated
area. Fluorescent paint used on the markers will make them more visible
during hours of darkness.
Equipment evacuated from a contaminated area must be marked. The type of
agent and current date and time should be posted on the markers with a
marker placed on each side, the front, and rear of the equipment.
