Foam Fire Suppression System

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.
Foam fire suppression system. They are mostly applicable to the protection of two dimensional flammable liquid hazards. Designing a foam fire suppression system requires special expertise expertise that wormald has developed over many years. 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. In this video fire protection expert lee kaiser discusses foam suppression systems the major characteristics and applications they are most commonly used for.
Low expansion where the bubble expansion ratio is small less than 20 to 1 and the bubble contains a high water content. For foam systems foam must be delivered to the fire efficiently and in. Foam suppression systems can be messy and require special strategies and considerations for clean up that other systems do not need. The size of the facility the hazard area to be protected the authority having jurisdiction and the assets being protected all play a big role in deciding what fire suppression system to use.
Foam water spray systems can be used for a combination of class a and class b hazards. Other components of fire retardant foams are. Foam concentrate water and air. The surfactants used must produce foam in concentration of less than 1.
Fire suppression foam is comprised of three parts. Every facility has different needs when it comes to fire suppression. Method of operation for foam water spray systems. Foam fire extinguishing system.
Foam systems come in two types as follows. 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. Foam water systems generally work by allowing foam concentrate to mix with water flowing into the piping system. Compressed air foam systems cafs when a wildfire strikes you need the best tools on hand to quickly bring it under control.
