Fire fighting foam properties.

It is this second approach that will be. Other components of fire retardant foams are. It is recommended for use between 1 3 proportioning ratio. Super high expansion foam.

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. The foam blanket blocks oxygen supply to the fuel. 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.

Fire fighting foam is a stable mass of small bubbles of lower density than most flammable liquids and water. A fire fighting foam is simply a stable mass of small air filled bubbles which have a lower density than oil gasoline or water. Liquid drains from the foam blanket and forms an aqueous film that suppresses fuel vapor and seals the fuel surface. Super high expansion foam is a synthetic fire fighting foam concentrate specifically formulated for either low medium or high expansion foam generating equipment.

Foam is made up of three ingredients water foam concentrate and air. The surfactants used must produce foam in concentration of less than 1. When mixed in the correct proportions these three ingredients form a homogeneous foam blanket.

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. 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.
