Firefighters have long relied on aqueous film-forming foam (AFFF) as a crucial tool in combating fires involving flammable liquids. Renowned for its capacity to smother fires by forming a protective film atop the fuel, this substance finds extensive application across industries. It’s widely utilized in aviation, petrochemicals, and military installations.
However, recent scrutiny has emerged regarding its environmental and health impacts, sparking a debate over its continued usage and regulatory oversight. In this article, we will carefully examine the environmental, health, regulatory, legal, and innovative dimensions surrounding AFFF usage in firefighting practices.
The Emergence of AFFF
AFFF emerged as a groundbreaking solution to combat fires fueled by flammable liquids, revolutionizing firefighting practices in the mid-20th century. Prior to its development, firefighters faced significant challenges in extinguishing such fires efficiently, often resulting in extensive property damage and loss of life.
The formulation of AFFF introduced a new approach, which was to create a protective film on the surface of the fuel. ConsumerNotice.org notes that this protective film prevents oxygen from reaching the fire. This effectively smothers the fire and prevents it from reigniting.

Owing to its effectiveness in suppressing fires involving liquid fuels, AFFF quickly found its use across various industries, including aviation, petrochemicals, and the military. Its widespread adoption underscores its pivotal role in mitigating fire-related risks and safeguarding both property and human lives.
Environmental Concerns
The environmental impact of AFFF, particularly its contribution to per- and polyfluoroalkyl substances (PFAS) contamination, has emerged as a significant point of contention. PFAS are persistent chemicals known for their adverse effects on ecosystems and human health.
The EPA notes that PFAS compounds have been found to accumulate in the environment, contaminating water sources and wildlife habitats. Recent data indicates that AFFF usage has resulted in widespread PFAS contamination, posing a significant threat to environmental integrity and biodiversity.
The persistence of PFAS in soil and water systems raises concerns about long-term ecological consequences. This has triggered calls for stringent regulatory measures to address contamination hotspots and mitigate environmental degradation.
Health Risks for Firefighters
Exposure to PFAS present in AFFF poses significant health risks to firefighters, with studies linking PFAS exposure to various adverse health outcomes. According to reports, firefighters exposed to AFFF during firefighting operations may face heightened risks of cancer, reproductive disorders, and immune system dysregulation.
Recent data highlights a concerning trend of elevated cancer rates among firefighters, particularly those with prolonged exposure to PFAS-containing firefighting foams. The carcinogenic properties of PFAS compounds raise alarm bells within the firefighting community, prompting calls for enhanced protective measures and awareness campaigns.
Regulatory Response
In response to mounting evidence of risks associated with AFFF, regulatory agencies have initiated measures to reassess its usage and mitigate PFAS contamination. Recent regulatory developments include efforts to restrict or ban PFAS-containing firefighting foams in many jurisdictions worldwide.
According to a March 2024 update by the Lawsuit Information Center, there are over 7,000 pending AFFF lawsuits in South Carolina multidistrict litigation. These lawsuits encompass claims from individuals and water supply companies seeking compensation for health issues and environmental contamination caused by AFFF.
The regulatory landscape surrounding AFFF continues to evolve, with policymakers and industry stakeholders collaborating to establish comprehensive frameworks for PFAS management and mitigation.
Alternatives and Innovations
The controversy surrounding AFFF has spurred innovation in the development of alternative firefighting agents and technologies aimed at addressing environmental and health concerns. Fluorine-free foams and specialized extinguishing systems have emerged as promising alternatives to traditional AFFF formulations, offering effective fire suppression capabilities while minimizing ecological footprint.
Research into fluorine-free foams and innovative extinguishing technologies has gained traction in recent years, driven by the imperative to transition toward sustainable firefighting practices. These advancements not only mitigate environmental and health risks associated with AFFF but also foster resilience and adaptability in firefighting operations.
Lawsuits and Legal Battles
The proliferation of lawsuits against manufacturers and users of AFFF underscores the growing recognition of its adverse environmental and health impacts. TorHoerman Law notes that plaintiffs in these lawsuits allege negligence, failure to warn, and environmental contamination, seeking accountability for damages incurred due to exposure.
According to an AFFF lawsuit update from June 2023, 3M offered a $10 billion settlement in an attempt to resolve AFFF litigation. However, the settlement remains tentative, highlighting the complexity and protracted nature of legal battles surrounding AFFF-related claims.
Future Directions
The firefighting industry faces the challenge of reconciling the need for effective fire suppression with the need to minimize the risks associated with AFFF. Research into safer alternatives and innovative extinguishing technologies is paramount to transitioning towards a more sustainable and health-conscious firefighting system.
Regulatory efforts to address PFAS contamination and enforce stringent standards for firefighting foams play a pivotal role in shaping the future of firefighting practices. Collaborative initiatives between policymakers, industry stakeholders, and environmental advocates are essential to driving systemic change and promoting the adoption of environmentally sustainable firefighting solutions.
FAQs
Can you still use AFFF?
Yes, AFFF is still used in firefighting operations, although its usage is extremely limited due to concerns over environmental and health impacts. Regulations and efforts to develop safer alternatives are underway to mitigate these concerns while ensuring effective fire suppression.
Who manufactured AFFF?
AFFF has been manufactured by various companies, including 3M, DuPont, Kidde-Fenwal, and others. These manufacturers produced AFFF for use in firefighting operations across industries such as aviation, petrochemicals, and military installations.
What is another name for AFFF?
Another name for aqueous film-forming foam (AFFF) is firefighting foam. It is commonly referred to simply as foam within the firefighting community and is recognized for its effectiveness in suppressing fires involving flammable liquids.
In conclusion, the legacy of aqueous film-forming foam (AFFF) in firefighting embodies a complex narrative of efficacy and controversy. While historically celebrated for its pivotal role in combating fires involving flammable liquids, recent investigations have exposed its negative impacts.
The emergence of safer alternatives and innovative extinguishing technologies signals a necessary shift towards more sustainable firefighting practices. However, ongoing legal battles and regulatory efforts underscore the urgency of addressing past damages and implementing robust measures to prevent future harm.
Collaborative initiatives are essential to navigate this multifaceted landscape, ensuring the protection of both human health and environmental integrity in firefighting operations.
