The present technology essentially is a portable fire damage reducing system and method including a fluid system for storing or dispensing a fluid. The fluid system can include a head unit, a body unit and a tail unit. The head unit can include a first end connectable to a fluid source. The body unit can include a first end connectable to a second end of the head unit, and a second end. The body unit can be configured to store fluid or to deliver fluid. The tail unit can include a first end connectable to the second end of the body unit, and a second end having a configuration capable of being open to the atmosphere for dispensing the fluid from the body unit or connected to the first end of the head unit to form a closed looped system with the fluid stored in the body unit.

A fire safety and extinguishing system for an electrical energy storage system includes at least one sensor for detecting a hot spot abnormality in the electrical energy storage system; a fire extinguisher installed inside a housing of the electrical energy storage system, wherein the fire extinguisher is configured to dispense an extinguishing agent when a hot spot abnormality in the electrical energy storage system is detected; a liquid separator arranged to receive an ethylene glycol and water mixture from a cooling reservoir, and to separate water from glycol. An outlet of the liquid separator is fluidly connected to an inlet of the housing of the electrical energy storage system to provide pressurized extracted water to the fire extinguisher as the extinguishing agent.

A system for forming and maintaining GPS tracked and mapped environmentally-clean chemical-based fire protection zones formed over property and ground surfaces in and about a neighborhood of homes, that proactively inhibit fire ignition and flame spread when exposed to wild fire. The system includes a GPS-tracking anti-fire (AF) liquid spraying system wirelessly connected to a wireless communication network supporting a network database. The GPS-tracked anti-fire liquid spraying system is used to spray particular GPS-specified ground surfaces in and about the neighborhood, with an environmentally-clean anti-fire chemical liquid so to form environmentally-clean chemical fire protection zones over the GPS-specified property surfaces, while generating GPS-coordinate and time/date stamped data records pertaining to the application of the environmentally-clean anti-fire chemical liquid spray during the formation of the environmentally-clean chemical fire protection zones. The GPS-coordinate and time/date stamped data records are transmitted over the wireless communication network for storage in the network database. A mobile computing system is used to access the GPS-coordinate and time/date stamped data records from the network database, relating to the formation of the GPS-specified environmentally-clean chemical fire protection zones, so as to verify that the GPS-specified environmentally-clean chemical fire protection zones were formed at the GPS-specified property surfaces on the particular date, to proactively inhibit fire ignition and flame spread when exposed to wild fire.

A burglar defense or fire suppression system for a structure or location having a dispensing system for selectively dispensing water, or a deterrence or fire suppression substance, the system being retrofitted to utilize existing structures for substance distribution; and a sensing system operably mounted to the system, wherein the dispensing system is operable to dispense the deterrence or fire suppression substance when an intrusion or fire is sensed by the sensing system or when remotely activated.

A pump intake pressure control apparatus includes an intake conduit joining a pump to either a pressurized or unpressurized liquid source, a wide-range flow controller configured to control the flow of liquid through the intake conduit, pressure sensors for detecting the pressure of the liquid in the intake conduit upstream and downstream of the flow controller, and an electronic master controller programmed to receive input from the pressure sensors and to actuate the wide-range flow controller to maintain the pressure downstream of the wide-range flow controller at or below a predetermined desired value. In one embodiment of the invention, the wide-range flow controller is a branched portion of the intake conduit having a valve in each branch. In another embodiment of the invention, the flow controller is a gate valve having a stationary triangular blocking member projecting into the passage between the inlet and outlet ports of the valve.

A fire-hose nozzle includes a cylindrical housing having an inlet, an outlet and a water passageway therebetween. Centrally disposed within the passageway is an elongated, rocket-shaped stem having a larger-diameter end near the inlet and a pointed, tapered end near the outlet. Proximal the inlet are circumferentially disposed apertures for injecting ambient air into incoming water to widen the spray pattern through the outlet. Attached to the inlet is a pistol-grip controller for coupling with a conventional fire hose. Therefore, when water is delivered to the housing, the stem disrupts and separates the water stream to decrease hose back pressure, recoil and oscillation.

A modular system is disclosed for handheld nozzles to facilitate distinguishing various nozzles in terms of nozzle type, owner, or type of fluid. Modular attachments are removably coupled to handles of the nozzles to provide the distinguishing characteristics. The modular attachment are secured to the handles without the use of mechanical fasteners or adhesives, and, instead, utilize integral mechanical attachment methods. The modular attachments can be made in a variety of colors to enable color-coding the distinguishing characteristics.

A firefighter training unit for simulating use of a fire extinguishing system, the unit including: a reel; a user-manipulable nozzle; a hose having opposite ends attached respectively to the reel and the nozzle and being partially wound around the reel, wherein rotation of the reel in a first rotational direction allows the hose to be unwound from the reel; a motor configured to drive the reel in a second rotational direction which causes the hose to be wound onto the reel; one or more devices for providing one or more output signals corresponding to one or more simulated operating conditions of the fire extinguishing system; and a controller configured to drive the motor in response to the one or more output signals so as to apply torque to the reel in the second rotational direction to simulate forces applied to the hose during operation of the fire extinguishing system.
