  • Patent number: 10625107
    Abstract: A method for supplying fire suppressing agent to the interior of a container for an extended duration includes detecting sensor signals indicative of a temperature associated with a container, determining via a controller that the fire suppressing agent should be supplied to the interior of the container based at least in part on the sensor signals, and initiating via the controller expulsion of fire suppressing agent from a chamber containing fire suppressing agent. The method may further include puncturing a surface of the container with a puncture mechanism to provide flow communication between the chamber and the interior of the container to permit supply of fire suppressing agent into the interior of the container at a first time, initiating via the controller expulsion of fire suppressing agent from a second chamber containing fire suppressing agent at a second time after the first time, and supplying fire suppressing agent from the second chamber into the interior of the container.

  • Patent number: 9977963
    Abstract: A system and method for tracking the growth of large-area wildland fires. The technique includes monitoring wind conditions in and around a wildfire using near-surface-sited sensors deployed by a high-altitude long-endurance (HALE) unmanned aerial vehicle (UAV), such as the Global Hawk. The deployed sensors measure a localized wind vector at multiple locations within and surrounding the wildfire, and transmit the wind data back to the UAV for relaying to a command center operated by fire management authorities, where the wind data are used to assist decision-making, including as input into wildfire growth prediction models. The sensors may provide additional data such as local altitude/elevation, pressure, temperature and relative humidity. The UAV may also carry sensors that provide additional data to be used by the fire management authorities or the wildfire growth prediction models—such as infrared images defining actively flaming areas, and visual images which indicate vegetation type and density.

    Abstract: An aerial fire suppressant delivery system uses an outer box or like structure and an inner liner. The inner liner may be a polyurethane bladder with two or more plastic straps RF welded to the polyurethane bladder. The two or more plastic straps are attached both to the bottom surface of the bladder and to the top of the outer box, which is not attached to the sides of the outer box. A fixed or rotary wing aircraft drops the container filled with fire suppressant material. As the container falls, the top of the box flies from the sides of box and the top pulls against the straps. Because the straps are attached to the bladder by RF welding, the straps tear the bladder at their attachments and cause the bladder and container to release the fire suppressant material into the air over the target.

    Abstract: Aqueous droplets encapsulated in a flame retardant polymer are useful in suppressing combustion. Upon exposure to a flame, the encapsulated aqueous droplets rupture and vaporize, removing heat and displacing oxygen to retard the combustion process. A polymer encapsulant, through decomposition, may further add free radicals to the combustion atmosphere, thereby further retarding the combustion process. The encapsulated aqueous droplets may be used as a replacement to halon, water mist, and dry powder flame suppression systems. In one embodiment of the invention, the aqueous droplets include a gelling agent, such as sodium alginate, and are encapsulated in an alginate-based material.

  • Publication number: 20120073839
    Abstract: A fire extinguisher with an actuation mechanism includes a fire extinguisher body filled under pressure with a fire suppressant. The actuation mechanism includes a pneumatically controlled activation piston assembly that functions to control the release of the fire suppressant until desired by the user of the fire extinguisher. The activation piston assembly includes a housing in which a piston is positioned. The housing includes a first end and second end. The first end of the housing is covered with a first cap supporting a spring interposed between the piston and the first cap, and the second end of the housing is provided with a second cap. The piston, under the control of balanced spring bias and pneumatic pressure, allows for time controlled release of the fire suppressant from the fire extinguisher body.

  • Publication number: 20120031631
    Abstract: Improvements to a portable fire extinguisher are disclosed. The improvements allow for frequent and simpler untrained and automatic self-servicing of a fire extinguisher. The improvements include an anti-bridging mechanism that fluffs, mixes or stirs the powder within the chamber to keep it in a liquefied state. Additional improvements include a larger opening to more quickly fill and inspect the powder within the chamber. Another improvement includes the use of a CO2 canister located external to the chamber to allow easier servicing or replacement of just the CO2 canister as well as the ability to maintain the chamber in an un-pressurized condition, allows for non-HASMAT shipping. These features will extend the service intervals while maintaining the fire extinguisher in a ready condition.

  • Publication number: 20120000679
    Abstract: This invention relates to a fire extinguisher structure in which a bottle mouth is extended upward on the top end of the bottle body, a socket being provided on the bottom of a nozzle, an inner and an outer thread segments engaging with each other being respectively formed on the socket of the nozzle and the bottle mouth of the bottle body, a plug being extended from the center of the socket of the nozzle for blocking the aperture of the bottle mouth and being in transitional fitting therewith, a leak-proof ring being put over the plug of the nozzle for abutting against the end face of the bottle mouth. In this manner, leakage of high pressure gas contained within the fire extinguisher can be effectively avoided by the plug blocking the bottle mouth, the leak-proof ring and the socket.

  • Publication number: 20110042108
    Abstract: A portable compressed gas foam system having a rocket engine, fueled with hydrogen peroxide and a suitable propellant, which produces exhaust gases. The exhaust gases are injected into a water tank, aerating the water and pressurizing the water tank. Foam concentrate may be added to the tank or separately in a mixing stage and is aerated by the aerated and pressurized water. The aeration produces bubbles in the foam and entrains exhaust gas within the bubbles. The aerated foam can then be sprayed onto a fire through a foam injection nozzle, extinguishing the fire both by wetting the burning materials and by smothering it by reducing the amount of oxygen available to burn. The invention may also be adapted for use in a firehose or in an underslung bucket.
