The invention presents a firefighting system for an extractor duct, in particular of a cooking area, having a duct, which has an inlet side and an outlet side, which is spaced apart from the inlet side, and defines a direction of the extracted air flow from the inlet side to the outlet side. The invention also proposes that at least one spray mist nozzle, preferably a plurality of spray mist nozzles, are installed in the firefighting system, said spray mist nozzles each having a plurality of separate spray mist outlets, wherein the spray mist outlets each have a predetermined K-factor and are oriented at an angle to one another.

A method of proactively defending combustible property against fire ignition and flame spread in the presence of wild fire. The method involves establishing wireless communication between a GPS-tracking anti-fire (AF) chemical liquid spraying system, and a wireless communication network supporting a network database. The GPS-tracking anti-fire chemical liquid spraying system is used to spray an environmentally-clean anti-fire chemical liquid over the exterior surfaces of a GPS-specified combustible parcel of property, and generating a GPS-coordinate and time/date stamped data records pertaining to the application of the environmentally-clean anti-fire chemical liquid spray over the exterior surfaces of the GPS-specified combustible parcel of property. The GPS-coordinate and time/date stamped data records are transmitted over the wireless communication network for storage in the network database. A computing system is used to access the GPS-coordinate and time/date stamped data records from the network database, so as to verify that the GPS-specified parcel of property has been fire-protected on particular date by virtue of the GPS-specified property being sprayed with the environmentally-clean anti-fire chemical liquid so as to proactively inhibit fire ignition and flame spread in the presence of wild fire.

An apparatus for a bulldozer that makes the process of controlling a wildfire safer and more effective. The apparatus includes a large capacity water tank that can be mounted to a rear of dozer using a frame. A pump can draw water from the water tank and pump the water at a high pressure. One or more hose reels can also be provided. Strategically positioned sprayers can spray water to nearby surrounding, in particular, on the Fireline made by the dozer. A major safety feature is a remote controlled monitor mounted on the front of the dozers can spray water directed by the operator can protect the dozer from fire as well as fire personnel if a fire comes at the dozer or fire personnel.

A dual air vent assembly for wet pipe fire protection sprinkler systems allows air or gas to vent from system pipes as they fill, without spilling any water into the fire-protected environment, even if an air vent valve, operative to discharge air or gas but not fluid, fails. A shut-off valve is upstream of the first air vent valve, and a reservoir is downstream of it. Small amounts of water that escape the first air vent valve are collected in the downstream reservoir, and evaporate. The reservoir also collects fluid if the first air vent valve fails. In response to fluid in the reservoir at or above a predetermined level, the shut-off valve is actuated to arrest the flow of fluid into the first air vent valve. No water escapes the assembly, even if the first air vent valve fails. The shut-off valve may be electronically or mechanically actuated.

The present invention refers to a method and system for ejecting carbon dioxide as High-Speed Jets with Sublimation. More specifically, the present invention describes a method and system capable of controlling and extinguishing fires from the CO.sub.2 ejected. In summary, the proposed method comprises the steps of removing CO.sub.2 in a first state (G) from the storage medium (2) and inserting the CO.sub.2 in first state (G) in the driver set (3); maintaining the insertion of CO.sub.2 in first state in the driver set (3) up to the equalization of the internal pressure between the storage medium (2) and the driver set (3); removing carbon dioxide in a second state (L) from the storage medium (2) and inserting the carbon dioxide in second state in the driver set (3) after the equalization of the pressure of the storage medium (2) and of the driver set; ejecting the CO.sub.2 in the form of high-speed jets with high content of CO.sub.2 in third state (S) through the driver set (3).

An electric outlet fire detection and prevention system may comprise a temperature sensor and an electromagnetic interference (EMI) sensor. A processor within the system may monitor the measurements of the temperature and EMI sensors to determine that a fire has developed in an electric outlet box. The processor may then actuate a triggering mechanism in a cartridge containing fire extinguishing material such that the fire extinguishing material is dispersed in the outlet box. The fire extinguishing material may extinguish a developing fire and prevent the fire from spreading further. The processor may also be coupled with a server, which is configured to analyze measurements of the temperature and the EMI sensors and generate a building profile. When the server determines that any measurements deviate from the building profile, the server may instruct the processor to actuate the triggering mechanism and/or notify an electronic device associated with the building.

Multiple robotic monitors are located in a hydrocarbon storage or transport facility. Each robotic monitor is communicably coupled to other robotic monitors and includes a heat sensor configured to detect heat emitted by a hydrocarbon tank of the hydrocarbon storage or transport facility. A controller is communicably coupled to the heat sensor and configured to generate a heat signature based on the heat detected by the heat sensor. A pump is communicably coupled to the controller and configured to exert pressure on a fire retardant, responsive to the generation of the heat signature by the controller. An outlet is mechanically coupled to the pump and configured to discharge the fire retardant at the hydrocarbon tank.
