Fire Fighting Foam Properties

Super high expansion foam is a synthetic fire fighting foam concentrate specifically formulated for either low medium or high expansion foam generating equipment.

Fire fighting foam properties.

An alternative approach is to examine all the properties of fire fighting foams in order to identify the characteristics that need to be optimised in order to provide the overall suppression performance equivalent to afff or fffp4 foams in the absence of the film forming surfactants. Other components of fire retardant foams are. It is recommended for use between 1 3 proportioning ratio. A fluorosurfactant free training foam which mimics the application and physical properties of angus petroseal c6 3 fffp fire fighting foam.

A fire fighting foam is simply a stable mass of small air filled bubbles which have a lower density than oil gasoline or water. Tf3 is a natural protein based product which mimics the performance of angus petroseal c6 3 fffp an aviation industry standard for protein based fire fighting foams to provide realistic fire training without the use of fluorinated chemicals. Super high expansion foam. Liquid drains from the foam blanket and forms an aqueous film that suppresses fuel vapor and seals the fuel surface.

The foam blanket blocks oxygen supply to the fuel. When mixed in the correct proportions these three ingredients form a homogeneous foam blanket. The surfactants used must produce foam in concentration of less than 1. The water content of the foam solution produces a cooling effect for additional fire suppression.

Use discharge and disposal of firefighting foam products usa. The fire fighting foam coalition fffc produced a three page document responding to the ipen paper which discusses technical details regarding differences in foam performance for certain types of class b fires and performance standards as opposed to composition standards that continue to necessitate the use of afff or other fluorochemical. Enhances the properties of protein foam by increasing foam fluidity and improves the properties of regular protein foam by providing faster knockdown and ex cellent fuel tolerance. 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.
