Foam:

WHY Utilize Foam?
Numerous specialists can stifle a class “B” fire, in spite of, froth gives:
Classifications of class B fire:
Polar solvents:
Alcohols, esters,CH3)2CO, acids, ketones, hydrophilic, lacquer more slender.
Hydrocarbon fuel:
Raw petroleum, benzene, fuel oil, gas, stream fuel, naphtha, lamp fuel.
How putting out fires Froth Functions?
Kinds OF Froth Think:
Sort 1 : – 99% water 1% focus
Sort 3 : – 97% water 3% reflect
Sort 6 : – 94% water 6% focus
FOAM CONCENTRATE:
A froth think that has a fluorinated surfactant with settling added substance and engineered surfactants frothing specialists for Class An and B fires (just non polar dissolvable).
A froth think that is protein base with at least one fluorinated surfactant added substances for Class An and B fires
A froth think that has a hydrolyzed protein base with settling added substances appropriate for Class A and B fires (just non polar dis-solvable).
A froth think that is protein base with at least one fluorinated surfactant added substances for Class An and B fires.
