Beschreibung
Zusammenfassung:	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.
