Abstract:
A rock dusting composition composed of rock dust, e.g., limestone or other mineral dust, water, pumping aid, and polymer, e.g., acrylamide homopolymers, acrylamide copolymers, and combinations thereof, and a method for applying the composition to the surface of a mine. The composition has a water content and a polymer content sufficient to allow the polymer to (i) disperse water molecules within the composition and, upon drying of the composition, (ii) dissipate forming void spaces in the dried composition. The composition is useful for suppressing propagation of a flame and/or fire caused by ignition of coal dust and/or gas within a coal mine.
Abstract:
The instant invention relates to a super absorbent polymeric material which when added to water produces a gel that enhances the fire extinguishing properties of the water. A pre-measured quantity of the polymeric gel material is packaged in a small easily opened dispenser type container. The disposable container is readily accessible for easy and rapid use of the gel by the individual under exigent circumstances to mitigate the effects of a rapid rise of temperature within a burning vehicle. The use of the gel providing sufficient time for the vehicle to leave the hostile zone prior to the individual exiting the vehicle. The gel provides extinguishing properties and is capable of long term storage.
Abstract:
La mousse comprend un mélange de silice, d'une résine de polyorganosiloxanes et d'un durcisseur de polyorganosiloxanes, additionnée d'un isolant thermique et d'un agent d'adhérence. L'isolant thermique est du polyphosphate d'ammonium. La mousse est bien appropriée comme produit de remplissage, de cloisonnage dans des applications ferroviaires.

Abstract:
A fire control system (100) according to various aspects of the present invention includes an extinguishant (112) having a suppresant (210) and a thermal absorbant (212). The suppressant (210) is configured to suppress the fire. The thermal absorbant (212) is configured to absorb heat from the fire. In one embodiment, the thermal absorbant (212) is configured to absorb thermal radiation from the fire and inhibit reflection of thermal radiation from the suppressant and/or other surfaces back into the fire. In additional and alternative embodiments, the thermal absorbant (212) may be configured to transfer heat into the surface and/or interior of suppressant particles or droplets to promote activation of the suppressant.
Abstract:
Mixture of solids and gases, resulting in a product of low density which floats on inflammable liquids. In the case of fire, when used on the fire places itself between the fuel and the flame and separates one from the other. Since these are iced or cold they eliminate or reduce considerably the production of gases which emanate from the surface of the liquid and reduce the size of the fire. Since these are volatile at the temperature of the surface of the liquid in flame they produce a non-combustible cloud which suffocates the fire.
Abstract:
Implementations are disclosed herein that relate to a firefighting system. In an embodiment, the firefighting system comprises a conveyance configured to receive and elevate screened soil, a chute configured to receive the screened soil at an entry pint, and a nozzle configured to emit the screened soil toward a fire site. In an embodiment, the nozzle comprises an augmentation device configured to increase the flow speed of the screened soil.
