Abstract
A blast attenuator device is disclosed comprising a collapsible/inflatable cylinder for containment of a body of foam therein. The cylinder is provided with a slitted floor such that the explosive device to be contained can be inserted therethrough. The blast attenuator is self contained and is provided with a compressed gas cannister for inflating the cylinder and foam generating cannister for automatically dispensing foam into the cylinder. The blast attenuator device can be deflated and compactly rolled up from a cylinder eight feet in height and eight feet in diameter to a bundle approximately four feet long for convenient storage and transport. Once the blast attenuator has been unpacked and placed over the explosive device, the inflating device can be turned on, the cylinder automatically inflates, and the foam cannister automatically dispenses foam after cylinder inflation to a specified height.
