For decades, Aqueous Film-Forming Foams (AFFF) have been the cornerstone of firefighting, lauded for their effectiveness in extinguishing stubborn fuel-based blazes. However, a dark side has emerged in recent years, casting a shadow over this long-trusted fire suppressant. Per and poly-fluoroalkyl substances (PFAS), a class of man-made chemicals present in AFFF, have been linked to a range of serious health problems.
The AFFF dilemma ignites debate, balancing fire suppression needs against potential health risks in a complex equation. In this article, we delve deep into the controversy, examining AFFF’s role in fire safety and the evidence of PFAS exposure.
Understanding AFFF and Its Health Risks
AFFF, firefighting foam, praised for its rapid extinguishing capabilities, has been vital in suppressing formidable blazes for years. However, recent scrutiny has underscored the potential health risks associated with its use, particularly due to the presence of PFAS. These synthetic chemicals, ubiquitous in AFFF formulations, have been linked to a range of adverse health effects, including cancer.
Firefighters and personnel exposed to AFFF have heightened cancer risks, as demonstrated by research studies. PFAS compounds like PFOA and PFOS, with carcinogenic potential, raise concerns among firefighters and public health officials. AFFF exposure correlates with higher rates of testicular, kidney, and prostate cancers, according to epidemiological research.
According to TorHoerman Law, cancers linked to AFFF exposure encompass bladder, breast, colon, kidney, liver, and pancreatic cancers. Also, prostate, rectal, testicular, thyroid, lymphoma, leukemia, and neuroendocrine tumors are implicated alongside mesothelioma.
Rising health worries and PFAS pollution prompted public scrutiny and legal challenges against AFFF manufacturers, underscoring immediate attention. Also, individuals attributing health problems, such as cancer, to PFAS-laden AFFF exposure are seeking legal avenues for compensation. These victims, through firefighting foam cancer lawsuits, are demanding compensation like medical expenses, lost wages, pain and suffering, etc.
The lawsuit claims manufacturers were aware or should have been aware of PFAS risks but neglected to provide sufficient warnings. The AFFF dilemma underscores the complex realities of balancing safety and health. While AFFF remains a vital tool for firefighters, the potential health risks posed by PFAS cannot be ignored.
Firefighting Necessities vs. Public Health Concerns
AFFF stands as a critical line of defense for firefighters battling infernos involving flammable liquids. Its ability to extinguish these fires effectively protects lives and property. Data from the National Fire Protection Association (NFPA) highlights this necessity. In 2022 alone, US local fire departments tackled about 1.5 million fires, resulting in 3,790 civilian deaths and 13,250 injuries. Property damage totaled approximately $18 billion from these incidents.
Without AFFF, these fires could become exponentially more dangerous and destructive.
However, safeguarding public health cannot be compromised. PFAS, the chemicals that give AFFF its firefighting prowess, present a significant health risk. Studies are revealing a disturbing link between AFFF use and firefighter health. The National Desk reported that studies indicate firefighters have a 100% higher incidence of testicular cancer compared to the general population. Many attribute this elevated risk to the presence of PFAS in firefighting foam.
This data adds to the growing body of evidence highlighting the potential health risks associated with PFAS exposure in firefighting foams.
Addressing the AFFF dilemma requires a nuanced approach that balances competing priorities. Prioritizing firefighter safety and public health is crucial, while also ensuring continued access to effective fire suppression tools during emergencies. Achieving this balance is essential for safeguarding both lives and property.
Alternatives to AFFF: Exploring Safer Options
The AFFF dilemma has spurred a fervent search for safer firefighting foams. The ideal alternative would possess the firefighting efficacy of AFFF without the health risks associated with PFAS.
Several promising alternatives are emerging, including High-Expansion foam (Hi-Ex), which utilizes air and water for effective fire suppression. While not universally replacing AFFF, Hi-Ex foams are suitable for certain fires, especially those involving polar solvents. Water mist systems provide an environmentally friendly option, ideal for enclosed spaces. However, their effectiveness is limited in open-air fires with flammable liquids.
Also, Fluorine-Free foams (F3) eliminate PFAS and show promise in fire suppression, especially for Class B solvent fires. Research indicates F3s can match AFFF effectiveness with fuels like gasoline. However, further real-world testing is necessary to validate their efficacy across diverse fire scenarios.
JD Supra highlighted that FFF is lauded for its eco-friendliness and superior performance over AFFF in various aspects. The new FFF is biodegradable, PFAS-free, and compatible with multiple equipment systems. It surpasses AFFF in burnback, drain-time performance, and expansion ratio.
Regulatory Measures and Industry Responses
Mounting evidence on PFAS has spurred regulatory action, particularly in the United States. The EPA has released advisories detailing PFAS health risks and setting safe drinking water thresholds. These measures reflect increasing recognition of the need to address PFAS contamination and its potential impacts on public health.
The EPA set a non-enforceable lifetime health advisory level of 0.07 ppt for PFOA and PFOS, key PFAS compounds in AFFF. While not legally binding, this guideline informs public water systems about safe PFAS concentrations. It underscores the need for proactive measures to safeguard public health.
Several states have implemented restrictions on the use of AFFF in firefighting training exercises. Colorado Newsline highlighted that numerous US states are taking action against PFAS-containing foam, with Hawaii leading by banning it. Proposed bills in Alaska and Minnesota aim to regulate or prohibit its use, albeit with exceptions. Also, in January 2023, the Pentagon mandated the use of PFAS-free firefighting foam.
These restrictions aim to minimize the environmental release of PFAS associated with training exercises.
Regulatory actions and industry initiatives mark significant progress in tackling the AFFF dilemma, yet ongoing vigilance and research remain imperative. Evolving insights into PFAS health impacts may warrant further regulatory enhancements. Sustained backing for alternative development and testing is vital for a seamless shift from AFFF.
Frequently Asked Questions
What are the health risks associated with AFFF foam exposure?
AFFF foam exposure poses health risks, including increased cancer rates. Other concerns include reproductive issues and thyroid dysfunction.

Has AFFF been banned or restricted in any way?
AFFF has faced restrictions in some areas due to environmental and health concerns. Several states have proposed or implemented bans.
The Path Forward: Striking a Balance
Addressing the AFFF dilemma requires striking a delicate balance between effective fire suppression and protecting public health and the environment. Finding this equilibrium is essential for ensuring safety while mitigating potential risks.
Moving forward, stakeholders need to collaborate closely to develop comprehensive strategies that minimize risks while ensuring operational effectiveness. Investing in research and development for fluorine-free foam technologies is crucial for innovation. Stringent regulations must limit harmful chemical usage. Additionally, firefighting personnel require sufficient training and support.
