Fire Protection Foam, also locally know as Foam Fire Fighting System; is a system of firefighting, where water is not used. In certain cases, water can actually cause, the spread of fire; example, electrical fire or petroleum based fires. Here, automated fire protection is critical and has to be provided, yet water should not to be used. This challenge is met by the Fire Protection Foam.

How does the Fire Protection Foam System, actually works?

To sustain a fire, we require three things, Fuel, Ignition or Spark and Oxygen. These three elements form the basis of fire, also referred to as the Fire Triangle. If one of the elements is missing, the fire will not exist. Fire Protection Foam System, isolates the oxygen, from the fire or fuel.

When the Foam sprinkler detects that the fire is present, it is triggered. This causes the water to flow into the bladder tank. The foam concentrate, goes into the bladder tank via the proportioner. The proportioner, maintains and keeps in check the desired; percentage of foam. The foam is formed when the foam concentrate and the water mix, in the right proportion.

This foam passes though the pipes, under pressure and directly on the fuel or fire, though the sprinkler. The foam covers the fuel like a blanked and isolates the Oxygen. The Fire Triangle is now, broken.


Types of Class ‘B’ Foams:

Aqueous Film-Forming Foam(AFFF) : This is a high quality foam. It is popularly used in, refineries, airports and manufacturing plants. They can be used in a variety of mediums, they are hence very versatile.

High Expansion Foam : They are used in very large areas. Along with the area, they also cover a sizeable height; hence also used to provide three dimensional protection in areas like warehouses and ships. They seem to be very effective, where spillage or a hydrocarbon fire might take place.
