Apparatus and method for blast suppression

Abstract

An improved method of blast suppression involves forming a foam barrier in proximity to a bomb or other suspicious device. The foam is maintained in position by a containment structure which is inflated and kept in an inflated state by the foam used to form such barrier. Various containment structures and methods are disclosed for suppression of compression waves and combustion effects caused by an explosive event.

1 . A method for suppressing a blast from an explosive device comprising: 
 a) positioning a containment structure having an internal void near said explosive device, wherein said containment structure has an inlet orifice extending from the outer surface of said containment structure into said internal void;    b) connecting a conduit to said inlet orifice of said containment structure;    c) injecting flowable foam through said conduit and into said internal void of said container; and;    d) substantially filling the internal void of said containment structure and covering said explosive device with said containment structure.    
   
   
       2 - 5 . (canceled)  
   
   
       6 . The method of  claim 1 , further comprising the step of disconnecting said conduit from said orifice of said containment structure.  
   
   
       7 . The method of  claim 1 , wherein said containment structure is folded when it is positioned near said explosive device.  
   
   
       8 . The method of  claim 1 , wherein said containment structure is constructed from 3-mil visquine plastic sheeting.
