Fire Fighting Foam Properties

Commercial foams can also contain other ingredients, such as surfactants and fire retardants. In effect, these additional ingredients may affect the physical and combustion properties of the PUF. During the combustion process the foam decomposes into its initial constituents, namely TDI and Polyol, and eventually char.

Fire fighting foam properties. The foam floats on top of the flammable liquid and spreads across its surface. Due to this and its chemical properties, the foam blanket suppresses the release of flammable vapors, cuts off the supply of air and cools down the substance on fire. Consequent application of foam until fully covering the entire surface of the burning liquid will. The main properties of firefighting foams include: Some firefighting foams have also been developed specifically for use against class A fires. • Knockdown and extinction: the ability of the finished foam to control and extinguish. foam.-Firefighting Foam - Technical Fire Service Manual. Table 1: Overview of major international standards relating to low-expansion fire-fighting foams. The terms which are underlined indicate performance criteria embodied by a given standard. Standard Scope Application ICAO5 Foam concentrate: physical properties (pH, ν, sedimentation) Foam: extinguishment and burnback performance Protein Foam is formulated for fighting hydrocarbon fires with outstanding fuel shedding property. It works by forming highly stable foam and offers outstanding burn back properties. It can be ideally used in slightly polar fuels such as MTBE and MTBE blended gasoline.

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. Foam is made up of three ingredients - water, foam concentrate and air. When mixed in the correct proportions, these three ingredients form a homogeneous foam blanket. Features of fire-fighting foam "Titan" Fire-fighting foam, the characteristics of whichpresented in this article, has excellent indicators of adhesion to materials of various structures. Among its quality characteristics can be distinguished fire resistance, thermal insulation ability, as well as strength. A fluorosurfactant free training foam which mimics the application and physical properties of Angus Tridol C6 S AFFF 3% fire fighting foam.. Trainol 3 is a Fluorine-Free Foam (F3) concentrate for 3% usage, which has been specially formulated to provide a unique training foam with a synthetic base material but no fluorosurfactants. 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 surfactants used must produce foam in concentration of less than 1%. Other components of fire-retardant foams are.

A fire fighting foam composition is disclosed comprising water; diutan gum; one or more surfactants; and one or more water-miscible organic solvents. In some exemplary aspects, the foam may be a fluorine-free foam composition or a reduced fluorine content foam composition. Despite these developments, a common problem remained. Contamination of the foam by some liquids still rendered the foam ineffective. National Foam Inc. developed a solution in the 1960s called fluoroprotein foam. Not only did this new foam have superior oil-rejecting properties, but it also had a longer blanket life. U.S. Super High Expansion Foam. U.S. Super High Expansion Foam is a synthetic fire fighting foam concentrate specifically formulated for either low, medium, or high expansion foam generating equipment. It is recommended for use between 1% & 3% proportioning ratio. Protecting human health and safety through effective fire suppression is the foremost priority of most fire-fighting foam system, although some are solely aimed at asset protection. However, a balance between minimising the environmental impact, liabilities and the long-term harm to human health caused by use of PFASs in fire-fighting foams.

Foam Equipment. Firefighting foam equipment is needed to generate fire fighting foam to fight all types of fires. Firefighters mainly use portable tools including proportioners while mobile equipment including trailers are mostly used for high risk industrial fire fighting. 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. Fire-fighting foam is a stable mass of small bubbles of lower density than most flammable liquids and water.. 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. Included within our Protein Based Foam Concentrate range is a selection of Protein foams, Fluoro-Protein foams FFFP foams.. Fire Fighting Foam Concentrates for the professionals . Read More.

The Fire Product Search website is an ever-growing international community of fire chiefs, professional firefighters, fire training officers, and trade specialists covering the field of fire fighting and rescue.. With over 225,000 unique visitors each year and growing, Fire Product Search provides the latest information on fire fighting and fire rescue equipment as well as the largest and most. This paper examines the rheological properties of compressed-air foams and contains velocity profiles of foams flowing through straight horizontal tubes.. to account for a range of expansion ratios and pressures normally encountered during pumping of polyhedral-in-structure fire-fighting foams.. 15.8 mm in diameter, with foam generated by. A fluorosurfactant free training foam which mimics the application and physical properties of Angus Petroseal C6 3% FFFP fire fighting foam.. 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. The foam blanket blocks oxygen supply to the fuel. Liquid drains from the foam blanket and forms an aqueous film that suppresses fuel vapor and seals the fuel surface. The water content of the foam solution produces a cooling effect for additional fire suppression.
