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.
Fire suppression foam.
Class b fire foam.
Foam concentrate water and air.
Video shows a fire suppression system malfunction that covered two boeing 787s in foam.
However there does not appear to be any people in the videos underneath the foam sprays.
The surfactants used must produce foam in concentration of less than 1.
At these expansion ratios the bubble water.
Foam systems come in two types as follows.
The incident created quite a mess.
Other components of fire retardant foams are.
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.
Medium and high expansion where the expansion ratios are greater from 20 to 1 up to 1 000 to 1.
Wormald systems are reliable and suppresses the fire quickly giving you confidence that fire risks are reduced to acceptable levels.
Full suppression top tier reliability with prices below gsa pricing high efficiency fire suppression foam designed to cool and coat fuel while suppressing the combustion of class b fires and flammable liquids.
The foam is seen spraying directly on the aircraft and some other equipment.
Designing a foam fire suppression system requires special expertise expertise that wormald has developed over many years.
