What is a AFFF fire extinguisher used for?

Aqueous Film Forming Foam – AFFF extinguishes flammable liquid fires by forming an aqueous film on the surface of the liquid solutions. This type of extinguisher is particularly useful for a fire that may not be affected by water. The AFFF can quickly bring a fire under control.

What can a AFFF foam fire extinguisher be used on?

AFFF (Aqueous Film Forming Foams) Foam Fire Extinguishers are suitable to fight burning solids such as wood as well as liquid fires such as burning petrol.

What is AFFF foam used for?

Aqueous film forming foam (AFFF) is a highly efficient type of fire suppressant agent, used by itself to attack flammable liquid pool fires, and in conjunction with Halon 1301 to attack fires in Navy vessel machinery spaces.

How do AFFF fire extinguishers work?

How Does AFFF Work? … When applied to a hazard, AFFF produces an aqueous film that spreads across the surface of the fire to extinguish the flame. This film is what gives AFFF its name, and it works by suppressing flammable liquid vapor, effectively suffocating the fire hazard.

What type of fire is AFFF used on?

An AFFF Foam fire extinguisher is effective on Class A and Class B fires. It can be applied to Class B liquid spills to prevent ignition. They are ideal for emergency first response vehicles.

Are all foam fire extinguishers AFFF?

Foam (AFFF – Aqueous Film Forming Foam) Fire Extinguishers are suitable for use on Class A (wood, paper, material & cloth) Fires & Class B (Flammable liquids: spirits, diesel, petrol etc.) … This Dual Class A & B rating makes Foam (AFFF) Fire extinguishers ideal for any office environment.

What is full form of AFFF fire extinguisher?

Fomtec AFFF 1% A is an aqueous film forming foam concentrate (AFFF) consisting of fluorocarbon and hydrocarbon surfactants blended with various solvents, preservatives and stabilisers. The foam forms an aqueous film that rapidly cuts off the oxygen supply and knocks down the fire.

Is AFFF foam hazardous?

AFFF constitutes a U.S. Occupational Safety and Health Administration hazardous material because of its physical hazards, such as skin and eye irritation. Discharge of wastewater and runoff containing AFFF on land, at sea, or to surface water bodies is also subject to regulation under the Clean Water Act.

What is the main cause of fire?

Arson is the most significant cause of fire and accounts for a large proportion of all fire damage.

What is a 3 dimensional fire?

A three-dimensional fire is a liquid-fuel fire in which the fuel is being discharged from an elevated or pressurized source, creating a pool of fuel on a lower surface. Foam is not effective at controlling three-dimensional flowing fires.

What is the difference between AFFF and AR AFFF?


AFFF and AR-AFFF consist of essentially the same ingredients. These typically include fluorosurfactants, hydrocarbon surfactants, solvents, inorganic salts, corrosion inhibitors, water; and in the case of AR- AFFF, a polymer which is typically a polysaccharide.
