A device configured for fire suppression and containment.

A method for the suppression of coal seam fires provides for the location and determination of the boundaries of a coal seam fire, directing access to the coal seam, preparation of the coal seam prior to suppression and the suppression of the fire within the coal seam using a foam mixture, the method providing minimal impact and disruption to the surface above the coal seam fire.

An extinguishing system and method for extinguishing fires. The extinguishing system includes-a pump system for pumping extinguishing agent; one or more nozzles connected operatively to the pump system for the purpose of spraying extinguishing agent at a source of fire; a supply or inlet arranged on the pump system for the purpose of supplying extinguishing agent to the pump system; an extinguishing conduit with an extinguishing length arranged on the pump system for the purpose of supplying extinguishing agent to the at least one nozzle; and an extinguishing controller provided with an input system for inputting system data, including data about the extinguishing conduit, the pump system and the at least one nozzle. The extinguishing controller is configured to determine with the system data an operating pressure at or close to the at least one nozzle and thereby control the pump system.

A wildfire suppression system is shown that includes a detector that can identify a wildfire threat from an approaching wildfire. When a wildfire is detected, a fire suppression system is activated to pump a fire retardant product, such as water or foam, through a fire retardant distribution system to supply the fire retardant to a series of water dispersion devices that are positioned to protect a structure and a set of landscape elements such as trees, flowers, bushes, and shrubs. Various embodiments can include a fixed based non mobile wildfire suppression system having automatic notification to local fire and police authorities of the presence of the wildfire, and can also include local electrical power generating units that can provide the electrical power needed to operate and control the wildfire suppression system.

Firefighting devices and associated methods and systems for firefighting are described where the firefighting devices generally have a housing: at least one tank disposed in the housing and containing source material for a firefighting agent: a propellant system that is contained within the housing and operatively coupled to the at least one tank for deployment of the firefighting agent: a nozzle that is coupled to the propellant system for receiving and dispensing the firefighting agent: and a control unit that is coupled to the propellant system configured to autonomously control the firefighting device by activating the propellant system to discharge the firefighting agent through the nozzle to a portion of an operational region of the firefighting device based on analysis of sensor data obtained for a portion of the operational region or an adjacent area outside of the operational region or receipt of a signal from another device.

A wildfire defense system trailer and method of installing an automated sprinkler-based wildfire defense system on a home construction site before the starting of the construction phase of a home building project in a wildfire urban interface (WUI) region. The first commissioned automated sprinkler-based wildfire defense system will continue in operation all during the home building construction phase, and will only be decommissioned from operation, and removed from the premises (including the job-site wildfire defense system trailer being removed from the property) when construction of the wood home building project is totally completed, and the wood home building is ready for occupation. At the same time when the first system is decommissioned, a second permanently-installed automated sprinkler-based wildfire defense system will be completely installed within the new home construction, independent from the first system, and ready for commissioning to provide a new proactive measure of defense against a wildfire storm occurring after home building construction has been completed, thereby protecting all wood and combustible surfaces on the home and surrounding property, and preventing fire ignition and flame spread until the wildfire storm passes through the WUI region. By virtue of the present invention, it is now possible to significantly reduce the risk of wood home building construction projects occurring within a wildfire urban interface (WUI) region, and better support the underwriting of home construction and ownership insurance policies within such regions.

An autonomous firefighting tower is a structure that is deployed into a firefighting zone for extinguishing a fire as well as for protecting firefighting personnel on the ground. The structure is able to self-level when being deployed on uneven terrain and requires minimal setup aside from connection to an external water source. A plurality of tower supports is hingedly connected to a base platform and may be adjusted to the terrain. Additional adjustability is provided through a plurality of self-leveling legs. A plurality of stabilizing members provides structural support and stability to the structure during self-leveling and when deployed. A fluid dispenser is connected to the base platform. Water is provided to the fluid dispenser from an external source through a fluid conduit. A control unit and at least one camera allow a remote operator to operate the structure during a firefighting operation.

There is provided a mobile firefighting unit comprising a container having a reservoir portion and a utility portion. The reservoir portion comprises a reservoir for storing a fluid. The utility portion comprises a main pumping station in fluid communication with the reservoir, and a mobile pumping station connectable to the main pumping station through a hose extending outside the container. The mobile pumping station is deployable for firefighting purposes. A heating system is also positioned within the container for heating the interior of the container. A lighting system provides lighting for the interior of the container. The mobile firefighting unit is readily and quickly available for rapid deployment in a fire scenario under various climate conditions.

Implementations are disclosed herein that relate to a firefighting system. An example provides a firefighting system comprising a conveyance configured to receive and elevate screened soil, a chute configured to receive the screened soil at an entry point, and a nozzle configured to emit the screened soil toward a fire site, the nozzle comprising an augmentation device configured to increase a flow speed of the screened soil.

A fire-extinguishing equipment includes: a fire-extinguishing apparatus which transmits electromagnetic waves in a predetermined output direction and discharges an extinguishing agent; an electromagnetic wave-receiver which is provided in an fire extinguishing object and receives the electromagnetic waves; and a controller which controls the fire-extinguishing apparatus to start to discharge the extinguishing agent when the output direction is set to a direction of the fire extinguishing object and the electromagnetic wave-receiver receives the electromagnetic waves.
