Abstract: According to the present teachings, a system and method are provided for decontaminating a conduit or vessel contaminated with residual explosive material. The system can include a heated gas flow source for heating a gas and providing a flow of the heated gas into the interior of a conduit or vessel. The temperature of the heated flow of gas can be at or in excess of the break down temperature of the residual explosive material.

Abstract: A device and method for cleaning a sewer line, or other conduit, storage tank, or other vessel, of explosive material deposited in and/or on an inner wall thereof, includes placing a flexible hose containing a non-explosive pyrotechnic composition within the conduit or vessel, and burning the pyrotechnic composition. According to various embodiments, the non-explosive pyrotechnic composition can be a composition that burns, combusts, or deflagrates, at a rate that enables it to be classified as a D.O.T. class 1.4 explosive posing no significant detonation or blast hazard and that can be shipped to various locations using relatively inexpensive shipping means.
