F500EA is a fire‐suppression concentrate which, when diluted with water at just 1%, makes that water 20 times more effective as a fire fighting agent.
With F500EA mixed in the water, when applied to a fire or hot surface, the reduced surface tension of the water produces smaller droplets. These smaller droplets have a greater surface area than plain water and can absorb very much more heat energy, thus quickly extinguishing the fire.
The fire tetrahedron describes the four elements required to make a fire, namely: heat, oxygen, fuel and free radicals. F500EA tackles three of these elements simultaneously:
-F500EA rapidly reduces heat to below the auto‐ignition temperature, a major safety benefit allowing rescue personnel immediate access to the incident scene.
-F500EA encapsulates hydrocarbon fuels and vapours, resulting in a rapid reduction of Lowest Explosive Levels (LELs). Vapours are rendered non-flammable and non-ignitable.
-F500EA also interrupts the free radical chain reaction (free radicals are unburned gases released during combustion, that intensify the fire).
F500EA is sold in containers of 20 Litres.
