What is a afff fire extinguisher?
AFFF is Aqueous Film Forming Foam
What do the initials AFFF stand for?
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.
What kind of fire extinguisher is required in diesel fire?
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.
What is the suitable fire protection system to be used in a diesel engine generator room?
AFFF- Aqueous Film Forming Foam
Why is afff foam good for fire fighting?
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 AFFF is outdated technology and needs to be replaced by modern day technology.
What is AFFF made out of?
Water, foam concentrate, and air.
Where is a labs fire extinguisher located?
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.
Why gas helps to make the foam that firefighters use?
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.
How can AFFF stops aviation 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.
What does afff mean?
AFFF stands for Aqueous Film-Forming Foam. It is a type of firefighting foam used to suppress fires by creating a film on the fuel surface, preventing the release of flammable vapors. AFFF is commonly used for combating fires involving flammable liquids, such as gasoline or jet fuel.
How do you remove spray foam insulation from fiberglass?
acetone
Where would you use a foam fire extinguisher?
"foam" fire extinguishers are made for hydrocarbon fires...i.e: gasoline, diesel, etc. These fires are considered class "b" (flammable liquids), and are mostly used by professionals and in commercial and industrial settings. These extinguishers are charged with anther AFFF, FFFP, or AR-AFFF, however, these class of extinguishers are only rated class A & B fires and are hazardous to the environment, humans and animals in addition to being very corrosive.
