– Class A, B, C and F firefighting liquid agent and eco-retardant

Product Mar 1 - Flamark

Mar 1 is water additive firefighting agent and eco-retardant, specially designed for A, B, C and F fire classes, mainly for professional use.

When added to water in proper quantities, Mar 1 water additive suppresses, cools, mitigates fire and vapours, and provides insulating properties for fuels exposed to radiant heat or direct flame impingement. Mar 1 water additive reduce water’s surface tension and increase its penetrating and spreading abilities, provide enhanced cooling, emulsification, and foaming characteristics

This creates faster penetration and better fire control when attacking combustible class A, B, C and F fires. Mar 1 cools 21 times faster than water, and works to remove heat and the fuel sources from the fire tetrahedron.

Mar 1 is specially designed to apply on class A fires including wood, paper, coal, rubber, class B fires including hydrocarbons, petroleum’s – crude oil, gasoline, petrol…, class C fires include natural mains gas, liquid petroleum gases – butane and propane…, medical or industrial gases, class F fires include high temperature cooking oils used in large industrial catering kitchens, restaurants.

Class F conventional extinguishers agent are not effective for cooking oil fires, as they do not cool sufficiently or may even cause flash back and putting the operator at risk. Mar 1 water additive firefighting agent contain specially formulated chemicals, which, when applied to the burning liquid, cools and emulsifies the oil, extinguish the flame, sealing the surface and prevent re-ignition!

Mar 1 works best in stable fire fighting systems (sprinklers), but can also be used as extremely efficient content for traditional fire extinguishers located in buildings (3 kg, 6 kg, and 9 kg) with Flamark state of the art portable fire extinguisher nozzle!

Mar 1 extinguish fires quickly, eliminates smoke and remains on the extinguished surfaces as a coating which prevents re-ignition.

Mar 1 can be mixed with other fire fighting agents or foam concentrates.
