A fire protection system that includes a fluid supply and a fluid delivery apparatus. The fluid delivery apparatus receives fluid from the fluid supply and delivers a protectant solution to a building to prevent the building from catching fire. The fluid delivery apparatus includes an expansion chamber having an inlet for receiving fluid from the fluid supply, and an outlet where the protectant solution exits the expansion chamber. The fluid delivery apparatus also includes a resource line in fluid communication with the expansion chamber to provide a flame resistant substance to the expansion chamber from a reservoir. Further, the fluid delivery apparatus includes a vent line in fluid communication with the reservoir and the expansion chamber, a pressure difference between the vent line and the resource line causes the fluid in the vent line to push the flame resistant substance from the reservoir to the expansion chamber via the resource line. A method of installing the fire protection system on a building. The fluid delivery apparatus of the fire protection system can be provided to receive fluid from the fluid supply and positioned adjacent to desirous parts of the building to deliver a protectant solution from the fluid delivery apparatus to the building.

A method of providing a deluge system (10) on a boom (12) such as a boom that is used to conduct well flaring operations at an end thereof. The deluge system comprises a base unit (30), a stanchion (20), and a nozzle apparatus (22); the method comprising attaching the deluge system to a burner boom with a walkway, such that there remains a width of at least 30 cm clear passage on the boom's walkway after the deluge system has been attached. This provides an escape and/or rescue route for personnel should a dangerous situation occur, such as uncontrolled fire or personnel falling overboard. In preferred embodiments, the deluge system is attached to the boom outboard of handrail supports (which includes on a single handrail). The deluge system may have its own mechanism e.g. a winch, for moving the stanchion from a stowed position to an operative position which allows a safe and more optimum positioning of the stanchion away from the well flaring operation, as herein described. In a preferred embodiment, the stanchion is provided as part of a moveable member which is rotationally attached to a connection mechanism of the base unit at a connection point spaced away from an end of the moveable member. This allows the moveable member to have a counter weight system and reduces the amount of force required to move the moveable member, avoiding mechanical constraints.

A wide-area wildfire suppression system uses a network of geographically distributed water sprayers, and includes at least one wind sensor and a fire-suppression controller communicatively coupled to the water sprayers and the at least one wind sensor. The at least one wind sensor detects wind direction and communicates wind-direction information to the fire-suppression controller, which uses the wind-direction information to activate at least one of the water sprayers upwind of an asset or area to be protected. Parameters of the water spray, such as flow rate, droplet size, spray pattern, spray direction, spray elevation, or aeration, can be adapted based on wind direction or wind speed.

A modular fluid spray nozzle is constructed from an inner conduit, having a sidewall with a center hole, housed inside a center conduit that includes a window defined by a sidewall, and a flexible or rigid outer conduit wrapped around the center conduit and forming a chamber with the rectangular window. The chamber is in fluid communication with the center hole and with at least two apertures defined by the outer conduit. The inner conduit is configured to be coupled to any type of conduit material, such as PVC pipe or another modular fluid hose segment.

A forest fire spread prevention device as an automatic fire extinguishing device for a forest fire may suppress an occurrence of property loss and loss of lives by blocking the forest fire in the middle so that it does not spread to nearby private houses when a forest fire occurs. The forest fire spread prevention device can include a burlap bag-shaped outer skin member which is woven with a thermoplastic plastic tape having a melting point of 160 to 280° C. as a weft and a warp; and an inner skin member of a cylindrical container which is accommodated in the outer skin member and formed in a film shape prepared by extruding a thermoplastic plastic material having a thickness of 15 to 50 microns and a melting point of 110 to 130° C. in a cylindrical shape, and has an inner space filled with water.

A fire-protection system comprising two elements is disclosed: 1) A retractable fire-protection covering or mat that may be automatically deployed over a building and stowed after the threat has passed; and, 2) A water fire spray system for wetting the lower aspects of a building to protect the lower and uncovered aspects of a building from fire. Using these systems simultaneously allows the user to mitigate forest and brush fire threats that may periodically threaten a building.

A system and method for providing a wildfire home protection water blanket is disclosed. The system includes a plurality of water blanket distributors attached to and integrated into the fascia of a building, a water source and control components for connecting the plurality of water blanket distributors to a water source, and a water line connecting the plurality of water blanket distributors to the water valve, the water line receives water from the water valve upon receiving a user command. The plurality of water blanket distributors comprise an enclosure attached to and integrated into the fascia of the building under the eaves, a plurality of water distribution nozzles and a water line. The water source and control components comprise the water valve and a WIFI-enabled controller.

A device for shaping a pressurized liquid stream, the device including: (a) a conduit, adapted for intake and transmission of a liquid stream; (b) a shaping piece configured to shape the liquid stream into a liquid shield, the liquid shield resulting from the liquid stream impacting on the shaping piece. In some embodiments, the device further includes: (c) a lateral displacement mechanism adapted to adjust a distance between the conduit and the shaping piece.

Apparatuses and methods for protecting buildings which are likely to fall in the path of wildfire and/or strong wind are disclosed. The apparatus comprises two main parts: the first part comprises a set of rigid poles pre-installed in the ground surrounding a building to be protected, and, the second part comprises a set of frames, each frame supporting a mesh that, when extended over the building to be protected, shields at least a portion of the building underlying the mesh from the destructive force of fire and/or strong wind. The set of frames with its corresponding meshes, when assembled together, forms a continuous protective pyramid-shaped net that covers the entire building. The set of frames and the set of rigid poles have complementary mechanical receptacles to lock with one another so that the rigid poles collectively provide ground support when the frames are deployed over the building.
