2. Firefighting foam - Wikipedia

   en.wikipedia.org/wiki/Firefighting_foam

   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, thus achieving suppression of the combustion. Firefighting foam was invented by the Moldovan engineer and chemist Aleksandr Loran in 1902. [1] The surfactants used must produce foam in concentrations of ...

3. Twin-agent fire extinguishing system - Wikipedia

   en.wikipedia.org/wiki/Twin-agent_fire...

   A twin-agent fire extinguishing system (TAFES), also commonly referred to as a twin-agent unit (TAU), incorporates the benefits of dry chemical and foam (AFFF or CAFS) fire extinguishing agents. [1] It is most commonly used for AR-FF operations and in industrial areas with high class B hazards. [1]

4. Compressed air foam system - Wikipedia

   After testing a dry type 2 foam in several situations, Johnny Murdock notes, "The emerging consensus is that the dryer foams (type II; maybe type I) should be used to suppress vapors, protect unburned structures, build wildland fire lines involving unburned fuels; … and that structural fire suppression requires a wetter foam (type IV or type ...

   This resulted in a statewide sampling plan in 2013 and 2014 to determine the scope of PFAS contamination throughout the state, specifically around WAFB. As a result, several more contamination sites were found, including a nearby McDonald's store fire that was put out with AFFF firefighting foam. [41] [66] [67]

6. Fire extinguisher - Wikipedia

   en.wikipedia.org/wiki/Fire_extinguisher

   AFFF was developed in the 1960s under Project Light Water in a joint venture between 3M and the U.S. Navy. AFFF forms a film that floats out before the foam blanket, sealing the surface and smothering the fire by excluding oxygen. AFFF is widely used for ARFF firefighting at airports, often in conjunction with purple-K dry chemical.

   Further, should fire either be encountered in the cabin or extend there from an external fire, the ARFF responders must work to control/extinguish these fires as well. [1] Primary to the hazard mitigation and safe evacuation of ambulatory passengers is the need to perform rescue operations. Passengers unable to extricate themselves must be ...
