A first solution is mixed and diluted with diluting liquid to make a first dilute solution, a second solution is mixed and diluted with diluting liquid to make a second dilute solution, and the first dilute solution and second dilute solution, both diluted with diluting liquid, are mixed in a sealed tank.

There is provided an arrangement (100) which allows for mixing a first fluid with a second fluid at a predetermined volume mixing ratio in a capillary driven fluidic system. The arrangement (100) allows filling an initially empty mixing chamber (110) with the first fluid. The arrangement then allows emptying a predetermined fraction of the first fluid from the mixing chamber (110) such as to form an empty space in the mixing chamber (110). The arrangement then allows filling the empty space of the mixing chamber (110) with the second fluid, thereby allowing a predetermined volume of the first fluid to mix with a predetermined volume of the second fluid over time.

A “FirePOD” provides a self-contained, portable, standalone fire protection system that enables property owners, firefighters or others to mix and apply fire-protective gel or foam to entities such as structures, vehicles, vegetation, etc., to protect those entities from wildfire events or other external fire incidents. In various implementations, the FirePOD includes a recirculation-based mixing system for combining a mixture comprising a powder, liquid, or gel-based Thermal Protective Substance (TPS) with a volume of water or other liquid to produce the fire-protective gel or foam. By applying reconfigurable valves, one or more pumps are applied to both recirculate the mixture and, when sufficiently mixed, apply the resulting fire-protective gel or foam via one or more hoses or other dispensing mechanisms. In various implementations, the FirePOD is movable, and is manually or automatically propelled to locations suitable for applying the fire-protective gel or foam.
