You asked: Is PFAS still used in fire fighting foam?

According to the EWG, there are now safer and equally effective alternatives to AFFF, and many states are prohibiting the use of PFAS-based foams, such as AFFF and AR-AFFF. Further, the National Defense Authorization Act now directs all Department of Defense fire departments to stop using AFFF and AR-AFFF by 2024.

Does firefighting foam still contain PFAS?

Firefighting foams without PFAS are already used successfully around the world, but outdated federal guidelines have kept foams containing PFAS in use for training and firefighting at U.S. commercial and military airports.

What chemicals are in firefighter foam?

Aqueous film forming foams (AFFF) are water-based and frequently contain hydrocarbon-based surfactant such as sodium alkyl sulfate, and fluorosurfactant, such as fluorotelomers, perfluorooctanoic acid (PFOA), or perfluorooctanesulfonic acid (PFOS).

Why is PFAS used in firefighting foam?

Per- and poly-fluoroalkyl substances (PFAS) have been commonly used to improve the ability of fire-fighting foam to smother fire. In such ‘aqueous film-forming foams’, or AFFFs, these chemicals have been used on fires at many thousands of emergency and training sites worldwide over the past half-century.

Does C6 foam contain PFAS?

PFAS may not be listed under any active ingredients list, either. A good indicator that the foam contains PFAS is if it mentions fluorosurfactant, fluoroprotein, C6, or the use of “fluoro”, however, not all fluorinated surfactants are made of PFAS.

How do you dispose of firefighting foam?

Always dispose of fire fighting foam concentrate through a certified disposal company.

Is firefighter foam toxic?

Firefighting foam contains numerous toxic chemicals known as “forever chemicals.” These chemicals do not break down quickly and stay around for a long time. They are linked to a variety of chronic and disabling illnesses and conditions, especially cancers.

Is there PFAS in 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”).

What does PFAS do to humans?

A growing body of science has found that there are potential adverse health impacts associated with PFAS exposure, including liver damage, thyroid disease, decreased fertility, high cholesterol, obesity, hormone suppression and cancer.

Are PFAS still manufactured?

Although the original PFAS chemical used to make Teflon has been taken off the market, Teflon and other brands of nonstick cookware are still produced with new PFAS that may be no safer. PFAS chemicals are widely used to coat paper and cardboard wrappers for fast food and bakery goods.

When were PFAS phased out?

Between 2006 and 2015, in cooperation with the EPA, eight global companies with PFAS-related operations voluntarily phased out the manufacture of PFOA and similarly structured PFAS with longer carbon chains.

When was PFAS first used in fire fighting foam?

1979. Firefighting foam with PFAS – known as aqueous film-forming foam, or AFFF – used widely by civilian airports and fire departments.

Does high expansion foam have PFAS?

Protein Foam was produced without using PFAS. High-Expansion Foam is used in fighting Class-A, Class-B, and LNG fires both indoors and outdoors. … The PFAS chemicals are not PFOA or PFOS. However, in earlier fluoroprotein foams, PFOA and PFOS may have been present in low levels.

Is Fire Fighting Foam corrosive?

Ship decks have aqueous firefighting foam (AFFF) stations that are used for fire fighting. The foam is, however, corrosive and can make holes in the decks. Right beneath those holes tends to be important rooms or tanks. They certainly wouldn’t want something dripping onto a person or equipment.

Is C6 foam fluorine free?

National Foam’s latest range of foam concentrates incorporate both fluorinated foams, which contain only C6 fluorosurfactants and fluorine free foams. These products meet the same approvals, and deliver improved firefighting performance and reduced environmental impact.
