Low expansion where the bubble expansion ratio is small less than 20 to 1 and the bubble contains a high water content.
Foam fire suppression system.
Compressed air foam systems cafs when a wildfire strikes you need the best tools on hand to quickly bring it under control.
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.
Foam concentrate water and air.
Foam fire extinguishing 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 water spray systems can be used for a combination of class a and class b hazards.
In this video fire protection expert lee kaiser discusses foam suppression systems the major characteristics and applications they are most commonly used for.
The surfactants used must produce foam in concentration of less than 1.
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.
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.
Wormald systems are reliable and suppresses the fire quickly giving you confidence that fire risks are reduced to acceptable levels.
Foam water systems generally work by allowing foam concentrate to mix with water flowing into the piping system.
Other components of fire retardant foams are.
They are mostly applicable to the protection of two dimensional flammable liquid hazards.
Every facility has different needs when it comes to fire suppression.
Fire suppression foam is comprised of three parts.
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.
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.
For foam systems foam must be delivered to the fire efficiently and in.
Foam systems come in two types as follows.
