Fire extinguishing by explosive pulverisation of projectile based frozen gases and compacted solid extinguishing agents

InactiveUS7478680B2Enhance state artRate of successful fire intervention, containment and effective extinguishing is veryAmmunition projectilesFire rescueTerrainEngineering
This invention relates to a forest, terrain and urban fire fighting device and method, and more particularly, to a fire extinguishing system and method offering reduced risk of fire spread and safety of firemen. This extinguishing device consists of an encapsulated cryogenic projectile with a payload of solidified and frozen mixture of carbon dioxide, nitrogen, combination of gases and compacted solid extinguishing agents. These strategically located and cryogenically stored devices are launched at the outbreak of fire, aerially or terrestrially over a blaze. An embedded explosive charge is detonated at a predetermined and optimum height causing the solidified gases / compacted solid extinguishing agents to be dispersed instantaneously and forcefully over targeted and specified areas. The release of high pressure, low temperature oxygen exclusion gases penetrate the fire from above, chills the substrate and extinguishes the fire. As carbon dioxide is heavier than air it hangs as a cloud over the extinguished substratum effectively preventing reignition. Fly ash, fine quarry dust or any solid or semisolid extinguishing agent can also be made to disperse under force over the fires in the same mode which cuts off the oxygen supply to the burning substrates. By effectively checking and cooling the fuel complex substrate by successive pulverizations as needed this invention enables a low cost, scalable, and effective urban, terrain and forest fire intervention / extinguishing process.

Reed's high-rise emergency rescue egress system

From ancient history until now, man has constructed high-rise buildings of various kinds. They include monuments, castles, churches, office buildings, hotels, hospitals and residences. No matter how sophisticated construction techniques and technology have become, there is no system to transport people and equipment to or from selected locations between the ground level and roof of a high-rise; quickly, economically, consistently and safely outside the structure. Reed's High-Rise Emergency Rescue Egress System is such a system. This system solves the myriad problems which have existed for centuries relating to a need for external, vertical high-rise emergency evacuation and does so with substantial cost-efficiencies. Reed's High-Rise Emergency Rescue Egress System is comprised of varied electronic and mechanical components operating in unison. The three major pieces to the high-rise system are; a vehicle, a gondola and a roof-mount cantilever: The vehicle is a self-powered ground vehicle containing a gondola, stabilizing steel cables, drums, television screens, video cameras, communications, and remote control equipment. Once linked to a cantilever it provides power for lifting the gondola, equipment and personnel to monitor all activities below, beside or above the fire area. The self-powered cantilever is, remotely or manually, positioned on the roof of a high-rise building to a desired area of operation. The cantilever extends its connection arm over the edge of a high-rise building and lower cables to the ground rescue vehicle to make necessary connections with the gondola for traveling up and down the walls of a high-rise building. The cantilever roof-mount system is portable and contains steel cables, electric / hydraulic wenches, radio receivers, transmitters and video communication. The gondola, an enclosed cabin, is positioned on the rear, body portion, of the high-rise rescue vehicle. Once the gondola is linked to the vehicle and cantilever arm it becomes an exterior enclosed transporter in a matter of minutes. Reed's High-Rise Emergency Rescue Egress gondola will carry up to eight fully equipped firemen and can scale the wall of a burning building in minutes. The gondola carries firefighters and equipment below, beside or above the fire, while at the same time providing trapped building occupants a safe means of escape. A modified version of the gondola is used for high-rise building construction and maintenance.
