Abstract
Disclosed is a device which, upon impact, will broadcast a dry material such as fire-suppressing chemicals by explosive force. The device comprises an explosive charge within a frangible rigid-wall container, a dry powder payload within the container which substantially surrounds the explosive charge, and a fuse cord operably positioned between the explosive charge and an impact-activated detonator. Upon impact, the detonator will cause the fuse to be ignited. Ignition of the fuse cord, whether by the impact-activated detonator or an external source, will cause detonation of the explosive charge, thereby breaking the container and broadcasting the dry material outwardly therefrom.
