How AFFF Lawsuits Are Changing the Landscape of Firefighter Safety

Aqueous Film Forming Foam (AFFF) has been a vital tool for firefighters battling flammable liquid fires for decades. Unbeknownst to them, this lifesaver contained a hidden danger: per- and polyfluoroalkyl substances (PFAS), also known as “forever chemicals.” These toxic substances have been linked to a range of severe health issues, including cancer, infertility, and more.

The discovery of this threat has sparked legal action, with over 8,270 lawsuits filed against manufacturers like 3M and DuPont, as noted by TruLaw as of 1st June 2024. These lawsuits allege that the companies were aware of the risks associated with PFAS but failed to warn firefighters, exposing them to this silent enemy.

These AFFF lawsuits are reshaping the firefighting landscape, driving innovation in safety measures, and demanding a significant shift in how the industry protects its frontline heroes. 

The Ripple Effects of AFFF Litigation

Like a pebble tossed into a pond, the legal battles are creating ripples that extend far beyond the courtroom. Let’s explore how these ripples are transforming the firefighting landscape and what they mean for the future of fire safety.

Financial Burden on Manufacturers

Once hailed as a miracle solution for extinguishing flammable liquid fires, AFFF has become a financial catastrophe for its manufacturers. As the health and environmental repercussions of the “forever chemicals” within AFFF are revealed, the responsible companies face many lawsuits.

The cost of their negligence is immense. 3M, a leading AFFF manufacturer, offered a $10.3 billion settlement to resolve water contamination claims with U.S. cities and towns. This staggering sum represents only a portion of these companies’ potential liabilities.

DuPont, along with Chemours and Corteva, has agreed to a separate settlement of $1.185 billion to resolve all PFAS-related drinking water claims, as stated in their press release. These settlements, while substantial, are just the beginning. The actual financial impact of the AFFF crisis on these companies is yet to be fully realized.

Increased Scrutiny of Existing Practices

The AFFF lawsuits have impacted manufacturers’ finances and sparked a wave of regulatory action. Governments and agencies are now intensely focused on the dangers of these “forever chemicals,” closely examining existing practices and demanding safer alternatives.

The U.S. Environmental Protection Agency (EPA), often criticized for its slow response to environmental threats, has taken a significant step forward. In a groundbreaking move, the EPA has proposed stringent regulations for PFAS in drinking water. 

These regulations set a maximum contaminant level (MCL) of just 4.0 parts per trillion (ppt) for PFOA and PFOS – equivalent to a single drop of water in twenty Olympic-sized swimming pools. This bold move signifies a significant shift in how we view the acceptable levels of these chemicals in our water. 

Shift in Public Perception

The AFFF lawsuits are triggering a significant shift in how we view firefighter safety and the chemicals we allow daily. Suddenly, people who had never considered firefighting foam were asking tough questions. What are PFAS chemicals? Why are they in our drinking water? Why weren’t we warned about the dangers?

The answer is a toxic combination of corporate greed and regulatory negligence, which has led to increasing public outrage and a demand for accountability. 

This shift in public perception is a game-changer. It’s putting pressure on companies to develop PFAS-free products and clean up the mess they’ve made. It’s also forcing policymakers to take action, with the EPA finally proposing stricter limits on PFAS in drinking water.

The Innovation in Firefighting Foam

As the smoke clears from the AFFF battleground, a new wave of innovation is surging, driven by the urgent need for safer and more sustainable firefighting solutions. Fortunately, the firefighting industry is rising to the challenge, developing cutting-edge technologies that promise a brighter, cleaner future.

Fluorine-Free Foams (F3)

The firefighting world is abuzz with a new foam: Fluorine-Free Foams (F3). This innovative foam is taking center stage, offering a crucial alternative to the infamous AFFF foams and their persistent PFAS problem.

The Department of Defense (DoD) made a significant move by releasing specifications for F3 foams, marking a severe commitment to phasing out AFFF and embracing a safer, more environmentally friendly solution.

However, the transition has its challenges. Switching to F3 is more complex than replacing your old toothpaste. For one, F3 foams aren’t a universal solution; they might need to be compatible with existing firefighting equipment. 

Additionally, a study reveals that fluorine-free foams exhibit lower chronic reproductive toxicity to birds such as northern bobwhite quail, raising environmental and ecological concerns. But it’s important to recognize that this technology is still in its early stages, and further research is needed to determine potential risks to humans and contaminated sites.

As research and development continue, we can expect even more advancements in F3 technology. These foams are not just a safer option for firefighters and the environment; they’re a symbol of progress and innovation in an industry that’s long overdue for change. 


Eco-gel, a plant-based water additive, transforms into a potent firefighting hydrogel when mixed with water. Its unique properties make it stand out from traditional firefighting foams. This gooey substance effectively combats flames and boasts an environmentally friendly profile.

One of Eco-Gel’s standout features is its exceptional clinging ability. It adheres to surfaces, forming a protective barrier that blocks flames and cools hot spots. This stickiness not only aids in extinguishing fires but also helps prevent re-ignition, a common issue with traditional foams.

Compressed Air Foam Systems (CAFS)

Compressed Air Foam Systems (CAFS) are making waves in firefighting innovation. They are like a high-tech blender for firefighters, combining water, foam concentrate, and air to create a thick, dense foam that effectively combats flames. This special foam isn’t just fluffier and boasts superior adhesion, clinging to surfaces readily.

This stickiness allows the foam to coat burning materials more effectively, preventing them from reigniting. Additionally, the dense foam acts as a cooling blanket, rapidly reducing temperatures and suffocating the fire. The unique properties of CAFS foam make it a valuable asset in firefighting, enhancing the efficiency and effectiveness of firefighting operations.

Water Mist Systems

Water mist systems atomize water into a fine mist, creating a dense cloud of microscopic droplets ranging in size from 1000 to 10 microns. This vast surface area allows exceptional heat absorption, making them incredibly efficient at cooling down flames.

Additionally, water mist displaces oxygen, a crucial element for fire to thrive. The combined effect of cooling and oxygen displacement makes water mist systems powerful against various fires, from Class A (ordinary combustibles) to Class K (cooking oils and fats).


What Was the Leading Cause and Nature of Firefighter Injuries in the United States?

The leading cause of non-fatal firefighter injuries in the United States is overexertion and strain, often resulting in sprains and muscle pain. Other common causes include falls, slips, and exposure to fire products.

How Effective Is AFFF in Firefighting?

AFFF (Aqueous Film Forming Foam) is highly effective in suppressing flammable liquid fires (Class B), particularly hydrocarbon fuels like gasoline and oil. It quickly spreads over the fuel surface, forming a vapor-sealing film that extinguishes flames and prevents re-ignition. 

What Are the Environmental Effects of AFFF Fire Extinguishers?

AFFF fire extinguishers contain persistent, bioaccumulative, and toxic PFAS chemicals. These chemicals can pollute soil, groundwater, and surface water, posing risks to animals and human health. PFAS exposure has been linked to various adverse health effects, including cancer, hormone disruption, and immune system suppression.

In conclusion, while the road ahead may be extended and challenging, the AFFF lawsuits have ignited a spark of hope. They have demonstrated that change is possible, even when facing powerful opposition. By remaining informed, engaged, and vocal, we can all contribute to creating a safer and healthier future for firefighters and our planet.
