Foam Fire Suppression System

Medium and high expansion where the expansion ratios are greater from 20 to 1 up to 1 000 to 1 at these expansion ratios the bubble water content is low and the bubble is relatively light.

Foam fire suppression system.

Firefighting foam is a foam used for fire suppression its role is to cool the fire and to coat the fuel preventing its contact with oxygen resulting in suppression of the combustion fire fighting foam was invented by the russian engineer and chemist aleksandr loran in 1902. When a hangar foam fire suppression system inadvertently discharges the results can be damaging or even deadly. Our compressed air foam system cafs quickly delivers instantaneous fire suppression by discharging a large volume of high quality foam a material that is twenty times wetter than water and up to five times more effective. Low expansion where the bubble expansion ratio is small less than 20 to 1 and the bubble contains a high water content.

Fire suppression foam is comprised of three parts. Foam concentrate water and air. The surfactants used must produce foam in concentration of less than 1. A fire fighting foam is simply a stable mass of small air filled bubbles which have a lower density than oil gasoline or water.

Foam fire extinguishing system. Different varieties of foams and chemicals are used for different fire sprinkler applications so the system should be tailored to the exact needs of the facility the. Foam and chemical fire suppression systems are used to cool the fire and coat the fuel that the fire is consuming to prevent contact with oxygen and reduce combustion ability. High and low pressure co2 system foam used in fire protection is an aggregate of air filled bubbles formed from aqueous solutions and is of lower density than the lightest flammable liquids.

For example in 2014 a civilian worker at eglin air force base died after being trapped in a foam filled hangar during an inadvertent system discharge. Foam suppression systems can be messy and require special strategies and considerations for clean up that other systems do not need. Foam is made up of three ingredients water foam concentrate and air. When mixed correctly these parts form a homogeneous foam blanket that extinguishes flames by the combined mechanisms of cooling separating the flame source from the product surface suppressing vapors and smothering.

Compressed air foam systems cafs when a wildfire strikes you need the best tools on hand to quickly bring it under control. Foam systems come in two types as follows.
