The Use of Aqueous Foam for Blast and Agent Dispersal Mitigation

5 The Use of Aqueous Foam for Blast and Agent Dispersal Mitigation 

In this investigation Sandia examined the use of aqueous foam for blast mitigation. The foam can be used with the shaped charge burster detonation method or to mitigate the blast from an explosive overcharge. 

Another option is to use the foam with a shaped charge. This option would greatly reduce blast damage to nearby structures. The distance to which a 1 psi overpressure (an approximate condition for breaking 

The principal advantage of this option is the small amount of explosive that would be utilized and the correspondingly small blast effects. The principal disadvantages of this method are that a mess remains to be cleaned up at the working point and that the destruct charge must be aimed and applied in a device-dependent fashion. Confidence that the explosive potential of the device will be destroyed must be established. 

They recommend to stay with the 5 1 explosive overcharge. Additionally, they recommend evaluating the effectiveness of a steel cylindrical barrier in non-critical tests i.e., tests in remote areas on recovered munitions or using agent surrogates.
