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.

Provided herein is a fluid projecting platform. In some embodiments, the fluid projecting platform herein is configured for use in firefighting, crowd dispersion, agriculture or other related tasks.

The invention relates to an extinguishing nozzle adapter for mounting an extinguishing nozzle on a wall, having a housing and a chamber for receiving an extinguishing nozzle, wherein the housing has an extinguishing agent connection to the chamber, via which connection the chamber is able to be pressurized with extinguishing agent, wherein the chamber is designed to receive the extinguishing nozzle in a movable manner such that the extinguishing nozzle is movable back and forth between a first, retracted position and a second, advanced position, and is moved in the direction of the advanced position when the chamber is pressurized by means of the extinguishing agent.

A firefighting apparatus can include a system that applies a fire retardant material to provide a temporary fireproof and/or fire retardant coating to vegetation, structures and/or flammable materials. The apparatus can include a high capacity tank with an integral, internal agitator to mix liquid therein with a fire retardant polymer, such as a superabsorbent polymer, to produce a fire retardant coating material. The apparatus can include an upper deck to store bales of polymer and an access panel to load bales into the tank for continuous production of the coating material. Primary and secondary pumps can selectively pump the coating material in stationary and/or moving modes. The apparatus can be NFPA 1901 compliant, and can operate as a fire truck or vehicle. Optionally, the system can include a venturi to mix the polymer with liquid to produce the coating material. Related methods of use are provided.

Fire spikes and fire spike tips adapted to penetrate a surface and distribute a fire suppressant, such as, water, on the opposite side of the surface are provided. The fire spike tips include a cylindrical body having a first end adapted to be received by a conduit and a second end having a pointed projection adapted to penetrate the surface; an internal cavity in the cylindrical body having an open first end and a closed second end; a plurality of first orifices in the body, each of the plurality of first orifices directed in a first substantially radial direction; and a plurality of second orifices in the body, each of the plurality of second orifices directed in a second direction which at least partially intersects with the first direction of the plurality of first orifices. Kits for the fire spikes and methods of suppressing fire are also provided.

A wireless wild fire defense system network supporting proactive protection of life and property in GPS-specified neighborhoods using GPS-managed delivery of environmentally-clean anti-fire (AF) chemical liquid spray to property before wild fire reaches the neighborhoods. The wireless system network includes a GPS system for providing GPS-location services to each system components in the wireless system network. A wireless communication network supports one or more network databases accessible by systems and devices deployed on the wireless communication network. A fleet of mobile GPS-tracked anti-fire liquid spraying systems are assigned to GPS-specified neighborhoods for spraying anti-fire chemical liquid on combustible property, buildings, and ground cover to inhibit fire ignition and flame spread wherever the anti-fire chemical liquid is sprayed. When allowed to dry, the anti-fire chemical liquid provides fire-protection status to sprayed property that is GPS-tracked and mapped within a network database maintained on the wireless communication network, recording wherever the environmentally-safe anti-fire chemical liquid has been spray applied. The system network includes mobile computing systems, each running a mobile application and deployed to a property owner, spray contractor or other stakeholder, such as firefighters and property insurance inspectors, for remotely monitoring the fire-protection status of property in any GPS-specified neighborhood, at any time on any specified date, along with the status of active wild fires surrounding the neighborhood. A command center deployed on the wireless system network transmits wild fire alerts and notifications and property spray orders, and supports microservices configured for monitoring and managing GPS-tracked spraying operations within GPS-specified neighborhoods. Through GPS-managed delivery of anti-fire chemical liquid spray on property surfaces before arrival of wild fire, fire ignition and flame spread are inhibited, and human and animal life and property are protected.

A method of proactively protecting property and buildings constructed thereon from wild fire by spraying environmentally-clean anti-fire (AF) chemical liquid prior to the arrival of wild fires. Intelligence data is remotely collected relating to risks of wild fires in specified regions, and maintained in a network database, and used to generate anti-fire (AF) spray protection maps and task reports for execution in the specified region. Prior to the arrival of a wild fire to the region, and based on the GPS-specified anti-fire (AF) spray protection maps and task reports, application servers deployed on a wireless system network issue a request or order to the property owner, or its registered contractor, to apply clean AF chemical liquid spray on the GPS-specified parcel of property using a GPS-specified AF chemical liquid spraying system, so as to proactively protect the property prior to presence of wild fire.
