Abstract: A system (23, 300) including a fire extinguishing apparatus capable of delivering a high velocity stream of fluid and fire extinguishing agent, both the fluid and agent directed toward the fire, the apparatus comprising: at least an outer first tube (100, 34) having a first end and a second end, the first tube having a predetermined length L, inner diameter and outer diameter, an air permeable tube, hose or sack (120, 350) positioned inside of the first tube, the sack having a first tube end and a second tube end; the sack extending from a first position along first tube end to a second position along the first tube and terminating close to or at the second end of the first tube; fire extinguishing agent (160) located between the permeable tube and the inner diameter of the first tube; a dislodgable plug or breakable disk secured to the second end of the first tube to prevent contaminants from entering the first tube; a source of high pressure fluid (180) connected directly or indirectly such as through a manifold to the first end of the first tube, the source configured to deliver the high pressure fluid upon receipt of an activation signal causing pressurizing fluid to enter the first end of the sock, the gas flow causing the plug to dislodge and flowing out of the sock to push the fire extinguishing material out the now open second end of the first tube.
