Can foam be used to extinguish energy storage cabinet fires

What is a foam fire extinguisher?

When we talk about fire fighting using foam, we are referring to using a fire extinguisher which has foam as its active ingredient to extinguish class B fires. Class B fires are those that involve flammable liquids, liquefiable solids, oils, greases, tars, oil-based paints, and lacquers (i.e. flammable and combustible liquids).

Can foam be used to extinguish fires?

For years, foam has been used as a fire-extinguishing medium for flammable and combustible liquids.

How aqueous foam extinguish a combustible liquid fire?

Aqueous foam extinguishes a combustible liquid fire by combining cooling, separating the flame from the product surface, suppressing vapors, and smothering. Unlike other extinguishing agents like water, dry chemical, or CO2, stable aqueous foam uses these combined mechanisms to effectively put out the fire.

What is the difference between foam and water based fire extinguishers?

Unlike powder, foam can be used to progressively extinguish fires without flashback. Water cools burning material and is very effective against fires in furniture, fabrics, etc. (including deep-seated fires). Water-based extinguishers cannot be used safely on energized electrical fires or flammable liquid fires.

How does AFFF foam extinguish fires?

AFFF (Aqueous Film Forming Foam) extinguishes hydrocarbon flammable liquid fires by forming an aqueous film on the surface of the flammable liquid as the foam solution drains from the foam blanket. This is in addition to the extinguishing action of protein or fluoroprotein foams.

Is foam used in fire protection?

Foam is typically the fire suppression agent of choice in situations where combustible or flammable liquid is stored in tanks or bulk storage facilities. It is especially effective when the flammable liquid has a surface where the foam can be applied.
