What does 3% AFFF mean?

aqueous film forming foam concentrate
Fomtec AFFF 3% is an aqueous film forming foam concentrate (AFFF) consisting of a blend of fluorocarbon-, hydrocarbon surfactants and various solvents and stabilisers. Only C6 Pure fluorosurfactants are used in Fomtec AFFF-formulations.

What is F3 foam?

Universal®F3 Green 3%-3% is a superior quality 3% synthetic fluorine free (FF) foam concentrate, designed for extinguishing and securing Class A and Class B chemical fires.

What is the difference between AFFF and AR AFFF?

Specifically, AFFF use is extensive in the aviation, petroleum and firefighting world. It is efficient and has strong knock down on large fires, but like any other tool, it must be used and applied correctly. AR-AFFF is used with alcohol-based liquids/products.

What class of foam is AFFF?

Class B Foam
Class B Foam (also called AFFF): Used to extinguish Class B materials, which include gasoline, oil, and jet fuel.

What is 3% foam used for?

This synthetic foam concentrate is intended for firefighting applications at 3% solution in fresh, salt, or hard water. CHEMGUARD C3B foam solution utilizes three suppression mechanisms intended for rapid fire knockdown and superior burnback resistance: The foam blanket blocks oxygen supply to the fuel.

What is the difference between low expansion foam and high expansion foam?

Low-expansion foam expands less than 20 times when properly proportioned and agitated with air. The normal expansion range for low-expansion foams is usually 8 to 12 times. High-expansion foam is usually formed by blowing air through a solution-wetted netting or wire mesh.

What is Fluoroprotein foam?

Fluoroprotein foams are derived from protein foam concentrates to which small amounts of fluorochemical surfactants are added. The fluorochemical surfactants are similar to those developed for AFFF foam concentrates but used in much lower concentrations.

What is AR AFFF foam?

Alcohol Resistant Aqueous Film-Forming Foam (AR-AFFF) concentrates are high performance synthetic foam concentrates comprised of fluorosurfactants, hydrocarbon surfactants, water soluble polymers, fluoropolymers, and polysaccharide gums.

How many types of fire fighting foam are there?

LOW EXPANSION FOAM: Foam aerated to an expansion ratio of between 2 to 1 and 20 to 1. MEDIUM EXPANSION FOAM: Expansion ratio between 20 to 1 and 200 to 1. HIGH EXPANSION FOAM: Expansion ratio above 200 to 1.

What foam do firefighters use?

aqueous film-forming foam
Firefighters use aqueous film-forming foam (AFFF) to help extinguish difficult-to-fight fires, particularly fires that involve petroleum or other flammable liquids ‚ known as Class B fires. However, not all firefighting foams are classified as AFFF.

Is AFFF banned?

The military plans to phase out the use of firefighting foam containing PFOAs by October 2024, as directed in the National Defense Authorization Act of 2020. However, this deadline is still two and a half years away, leaving little protection for the people who are exposed in the meantime.

What is the mixing ratio for AFFF and water?

Fomtec AFFF 1% A should be used at 1% proportioning (1 part concentrate and 99 parts of water). May be used with all water types. Fomtec AFFF 1% A can be stored as premix when blended with fresh water.

What is the ratio of high expansion foam?

between 200:1 and 1000:1
HI-EX foam concentrate can be used to produce foam with expansion ratios ranging typically between 200:1 and 1000:1 depending upon the type of generator and the operating pressure.

Is high expansion foam to fight a fire on deck?

If we use high expansion foam for deck fires, the foam will fly with the wind and will not be able to extinguish the fire. For this reason, for deck fires low expansion foam is used. On tankers, it will always be low expansion foam for fires of the cargo area.

Is AR AFFF Class B foam?

Class B Foam Agents are ideal for suppressing fires involving petroleum-based products, LNG, rubber, and flammable and combustible liquids; such as diesel fuel, crude oil gasoline and ethanol.

Does AFFF foam expire?

Fire Fighting Foams usually have a very long shelf life, provided they are kept within the manufacturers guidelines and temperature limits and are stored in the original and unopened shipping containers. For example, a shelf life of 10–20 years can be expected for AFFF-LF and AFFF concentrates, if stored correctly.

What is the two basic types of foam?

Protein foams contain natural proteins and are generally biodegradable; synthetic foams are made of synthetic foaming agents.

Do firefighters still use AFFF?

Read more about ‘forever chemicals’ and what firefighters need to know about AFFF and PFAS here. Firefighters use aqueous film-forming foam (AFFF) to help extinguish difficult-to-fight fires, particularly fires that involve petroleum or other flammable liquids ‚ known as Class B fires.

Is AFFF foam toxic?

While AFFF is not dangerous in and of itself, it is the two groups of chemicals in it, namely PFOS and PFOA, which are highly toxic to our health. Thereby, exposure to AFFF can lead to various forms of cancer over the course of several years.

What is class A foam?

Class A foams are used to extinguish fires caused by wood, paper, and brush. Class A foams generally do not contain per- and polyfluoroalkyl substances (also known as “PFAS”).
