block letters (fluorescent paint if available) appears on the front
side of the marker (facing away from the contamination). The person

the date and time of detection on the front of the marker, using
paint, marking pencil, or grease pencil.
The chemical minefield marker (Figure 3-6) is a triangle that is red
on both sides. On the front side (facing away from the contamination)
appear the words GAS MINES in yellow, 2.5-centimeter (1-inch), block
