Abstract:
1. A hand-held fire extinguisher comprising: a tube having an open outlet end, an outer surface, and an inner surface; a dry fire suppressant composition coating the inner surface of the tube and providing a hollow propellant passage extending axially therethrough, the dry fire suppressant composition being exposed to the propellant passage axially along at least a substantial axial length of the propellant passage; a propellant source containing a propellant, having a propellant outlet, the propellant outlet being distal from the open outlet end of the tube and from the fire suppressant composition, and the propellant outlet being in fluid communication with the propellant passage extending through the coated dry fire suppressant composition and with the open outlet end of the tube; and an actuator for the propellant source; whereby actuation of the actuator allows propellant flow from the propellant outlet passing through the propellant passage extending through the coated dry fire suppressant composition such that the propellant will mix with the fire suppressant, and such that the propellant and fire suppressant mixture will exit out through the open outlet end of the tube.
