Abstract
A linear fire extinguisher includes a high strength metal elongated tube containing a pressurized fire extinguishant such as Halon 1301. A pair of these tubes are mounted opposite each other with a pair of opposed shaped charges placed along exterior walls opposite each other so that when actuated they provide cutting lines which release the extinguishant in opposed directions so that reaction forces balance out. Concurrently the unwrapping of each container is counteracted and interfered with by the adjacent container to minimize the spread of container fragments. Appropriate intermediate retention of portions of the container is provided to also minimize fragments.
