This appendix implements STANAG 2002.


This appendix discusses the marking of land areas that have become dangerous because of radio-active or CB contamination, chemical minefields, minefields other than chemical, booby-trapped areas, and unexploded bombs. These dangers are marked by triangular signs, unless the area is to be abandoned to the enemy. The front of each sign must face away from the contaminated or dangerous area.


The shape of the sign is a right-angled isosceles triangle (see Figure B-1). The base of the triangle is approximately 11 1/2 inches (28 centimeters) and the opposite sides are approximately 8 inches (20 centimeters) each. These dimensions may be varied to suit local material. Composition may be wood, plastic, or whatever at hand is best suited. Existing stocks of colored triangular signs of slightly divergent shapes and sizes may be kept and used until stocks are exhausted. Signs may be locally procured or built. The Minefield Marking Set, Contamination (NBC), may also be used.


The nature of the contamination or danger of the contaminated area is told by the colors and wording of the signs. The primary color is used for the background of the front and for the entire back of the sign. The secondary color is used for additional markings and inscriptions on the front. Color coding for various dangers is shown in Table B-1. The language to be used for the inscriptions is selected by the forces erecting the sign. These inscriptions are written parallel to the longest side of the sign (see Figure B-1).

In addition, when practical, details of CB or radioactive contamination are written on the front of each sign. For biological contamination and for persistent or moderately persistent chemical agents, the name of the agent used (when the agent is known) and the date and time of detection are required. In case of radioactive contamination, the following information is put on each sign: the dose rate, the date and time of reading, and the date and time of the detonation that produced the contamination (if known).


Areas that contain more than one type of contamination must be marked with as many relevant signs as necessary placed near each other. The sign "Gas Mines" can be assumed to include high-explosive mines or booby traps. Mined and booby-trapped areas are fenced and marked on the friendly side to warn friendly troops. Two strands of wire, preferably barbed wire, are used. The lower strand of wire is placed at ankle height, and the upper strand is placed waist high. Fencing on the flank and enemy side may be added when required for protection of friendly troops. Marking simulated contaminated areas is exactly the same as marking those that are real.

Signs, right-angled apex downward, should be placed on fences, trees, rocks, or poles or should be stuck in the ground. They should be stuck in the ground only if there is no other way to place them, because they are hard to see in the ground and can be easily knocked over. Signs must be placed IAW NATO standards, at least one sign every 15 meters.


There is no standard for lighting signs. Each unit provides lighting or reflective devices where necessary. Lit or reflecting markers should be faced away from dangerous areas.
