operations at the site is made. Refer to the applicable demilitarization DMWR for additional information
pertaining to the disposal of a specific munition. Pit- and trench-burning procedures are as follows:
Dig a pit or trench at least 1.22 meters (four feet) deep, with sides sloping enough to prevent a cave-in. The
size of the pit or the length and width of the trench are determined by the quantity of material being disposed
of and by the safety distances established for the burning site. Place combustible material (such as scrap
wood) at least 0.31 meter (one foot) deep in the bottom of the pit.
Place the munitions on the combustible material, ensuring that the combustible material extends beyond the
layer of munitions. Layers of combustible material and munitions may be formed as necessary, allowing an
air space of not less than 0.31 meter (one foot) between the top layer of munitions and the top of the pit or
trench.
