ABSTRACT:
A linear fire extinguisher system is described that includes a flexible, substantially closed plastic tube containing an extinguishant, the tube containing a multiplicity of selectively weakened pre-scored orifices at preselected spacing along the tube length, whereby sufficient heat from a fire contacting the tube will weaken and rupture the tube predictably and facilitate efficient discharge of the extinguishant directly onto the fire. The structure of the invention may include two coaxial inner and outer tubes, each tube containing extinguishant wherein the outer tube may initially rupture upon heating and discharge extinguishant onto the fire, the inner tube being available for rupture and discharge onto the fire upon re-ignition or if the discharge of the outer tube is insufficient to extinguish the fire.
