AFFF stands for Aqueous Film-Forming Foam, which is a type of fire-fighting foam used to extinguish flammable liquid fires. It works by creating a barrier between the fuel and the fire, suppressing vapors and cooling the fire's heat. AFFF is commonly used in aviation and industrial fire-fighting due to its effectiveness in combating hydrocarbon fires. However, concerns over its environmental impact, particularly regarding per- and polyfluoroalkyl substances (PFAS), have led to increased scrutiny and regulation.
AFFF stands for Aqueous Film-Forming Foam. It is used by fire fighters for the suppression of a fire where fuel is involved. It does this by coating the fuel and preventing oxygen enabling combustion.
AFFF is Aqueous Film Forming Foam
I wouldn't agree that afff is good for fire fighting. Perhaps at one time it was, before there were more cost effective and environmentally friendly options on the market. There are now wetting agents such as Novacool UEF (Universal Extinguishing Foam) that are a much better option. This foam, which is UL listed and certified under NFPA 18, is used at 1/6 to 1/12 of the concentration of AFFF and is bio-degradable. AFFF is most effective in a contained pool of Class B flammables but is not effective on 3 dimensional fires where Novacool UEF is. AFFF is outdated technology and needs to be replaced by modern day technology.
Aviation Rescue and Fire Fighting
Using the American system for classification, here's the general type of extinguisher used:A (combustible materials) - water, AFFF (aqueous fire fighting film), dry chemicalB (flammable liquid or gas) - NEVER water. Dry chemical, AFFF, Halon, CO2C (electrical fires) - NEVER water. Dry chemical, Halon, CO2D (flammable metals) - NEVER water. Dry POWDER (not dry chemical) such as sodium chloride granules, graphite or copper.

AFFF- Aqueous Film Forming Foam
AFFF or aqueous fire fighting foam is a chemical agent that is added to water usually at a rate of about 300:1 (300gal water for 1gal foam concentrate) this mixture is then mixed with the outside air as it exits the nozzle and creates a blanket of foam that suffocates the fire.
Because the Aqueous Film Forming Foam stops oxygen from reaching the fuel. Therefore removes the oxygen element from the fire triangle so a fire is not able to form.
aqueous film forming foam (AFFF), if you have one, although CO2 or dry-chemical fire extinguishers are also rated for combustible liquids, such as diesel.
Fighting Fire with Fire was created in 1991.
Laboratory fire extinguishers shoud be located just inside each exterior door. To be as safe as possible they should probably be of the type AR-AFFF, that is Alcohol Resistant Aqueous Film Forming Foam. While these foam extinguishers are messy they extinguish the fire AND THEN they provide reflash protection. Other extinguishing agents will extinguish the fire but if all the elements of a fire are still there, oxygen fuel and temperature, then the fire can reignite. AR-AFFF prevents that and prevents the foam from degrading due to solvents which tend to be present in Laboratories.
