Revetments Section 6F—Earth-Filled, Steel Bin-Type Barricades for Outside Storage

6.23. Earth-Filled, Steel Bin-Type Barricades for Outside Storage.

6.23.1. These barricades, also known as revetments, are earth-filled steel bins used to separate AE awaiting scheduled processing (e.g., AE on a flightline associated with aircraft parking or loading operations; or the temporary positioning of AE awaiting transfer to preferred, long-term storage). These barricades, also used to separate explosive-loaded aircraft, are normally used to form a series of cells. They are designed to limit the MCE, for QD siting purposes, of AE properly positioned in separate cells by preventing propagation to adjacent cells.

6.23.2. When properly sited, these cells prevent propagation; however; all assets in the series of cells are at risk of loss. Although a revetment is effective in limiting the blast loading of an adjacent ES to that produced by the largest contents of a single cell, there is a significant probability that the contents of many of the cells may be damaged or destroyed by the initial and subsequent fire and explosion events. The extent of such losses increases with the amount of explosives present.

6.25. Types of Revetments.

6.25.1. Type A revetments, which must be a minimum of seven feet thick, can be used to limit a MCE in a series of cells to the largest quantity in a single cell, provided the quantity in the single cell does not exceed 30,000 pounds NEWQD.
