A fire apparatus includes an engine, a fluid delivery system, and a controller. The fluid delivery system includes a first pump that provides a first fluid output at a first pressure, and a second pump positioned downstream of and coupled to the first pump in a serial arrangement. The second pump is driven by the engine. The second pump provides a second fluid output at a second pressure. During a first mode, the first fluid output is dischargeable from a low pressure discharge. During a second mode, the second fluid output is dischargeable from a first high pressure discharge and/or a second high pressure discharge, the engine operates at a first set point when the second fluid output is discharged from the first high pressure discharge, and the engine operates at a second set point when the second fluid output is discharged from the second high pressure discharge.

A forest fire retardant composition contains a retardant compound that includes a halide salt, a non-halide salt, a metal oxide, a metal hydroxide, or combinations thereof. The forest fire retardant composition may include at least one anhydrous salt and at least one hydrate salt. The halide salt may be magnesium chloride, calcium chloride, or both. The magnesium chloride hydrate has a formula MgCl.sub.2(H.sub.2O).sub.x, wherein x is at least one of x=1, 2, 4, 6, 8, or 12. The calcium chloride hydrate has a formula CaCl.sub.2(H.sub.2O).sub.x, wherein x is at least one of 1, 2, 4, or 6. The composition may be in the form of a dry concentrate, a liquid concentrate, or a final diluted product. The final diluted product is effective in suppressing, retarding, and controlling forest fires while exhibiting corrosion resistance and low toxicity.

The apparatus, system and method for the suppression and containment of wildfires is provided. The system can be designed as a mobile or a stationary containment system. Each system is operationally connected to a fan assembly that is in fluidic communications with a reservoir tank that is mounted within each, containment system. In one important aspect of the present invention each fan assembly can be customized and engineered to contain the associated wildfire environment.

A mobile firefighting system includes a water cannon enabled for spraying slush on or near a fire. The slush includes solid material (e.g., ice, solid fire retardant) that is projected farther than a liquid could be projected using high pressure. The slush has enhanced fire suppression and fire protection characteristics compared to a liquid. Multiple tanks add enhanced slush chilling capability (e.g., through sequenced chilling) and provide redundant backup systems. A mobile cannon includes multiple reducing nozzles that can be aimed by a rotating base and hydraulic cylinder (for raising and lowering). Continuous tracks and winches contribute to all-terrain capabilities.

A firefighting or rescue apparatus includes a frame having a cab defining an interior within which a flash memory device is permanently mounted. The flash memory device is isolated so that it is incapable of receiving any onboard operating data pertaining to the operation and status of the firefighting apparatus. Instead, the device primarily stores data regarding a service manual, maintenance manual, electrical diagrams and/or troubleshooting guide related to the firefighting apparatus. The device is able to be selectively coupled to a portable computing device so that a user working on the firefighting apparatus can access the data without risk of loss or misplacement thereof.

A fire truck operable to automatically refill a water tank comprises a first pressure transducer coupled to an intake inlet of the pump and operable to measure an intake pressure, a second pressure transducer coupled to a discharge outlet of the pump and operable to measure a discharge pressure, a first discharge pipe coupled between the discharge outlet of the pump and a fire hose, a second discharge pipe coupled between the discharge outlet of the pump and the water tank, a control valve disposed in the second discharge pipe, and a controller operable to automatically sense a low water level condition of the tank, and automatically control the engine speed, the pump speed, and the control valve so that adequate water supply to the fire hose via the first discharge pipe is automatically given priority and maintained while automatically refilling the water tank via the second discharge pipe.
