The number of legal claims involving aqueous film-forming foam (AFFF) continues to climb, with more than 10,000 AFFF lawsuits now pending in federal courts. These claims primarily involve allegations that exposure to toxic chemicals in AFFF, also known as firefighter foam, has led to serious health issues, including various forms of cancer.
What is Aqueous Film-Forming Foam?
Aqueous film-forming foam is a synthetic firefighting agent that has been widely utilized since the 1960s. Its primary function is to suppress flammable liquid fires, particularly those involving petroleum products. AFFF is composed of per- and polyfluoroalkyl substances (PFAS), a group of chemicals known for their resistance to heat, water, and oil. While effective in firefighting, these substances do not break down naturally, leading to significant environmental and health concerns.
Common Uses of Firefighter Foam
For decades, AFFF has been extensively used by military bases, airports, and industrial facilities. The U.S. military, in particular, has employed AFFF during training exercises and emergency responses. Until recently, the use of AFFF was mandated in certain situations, particularly at commercial airports, due to its effectiveness in extinguishing jet fuel fires.
Potential Health Risks Associated with AFFF Exposure
Scientific research has increasingly linked PFAS exposure to a range of serious and potentially life-threatening health conditions. Firefighters, military personnel, and residents living near PFAS-contaminated sites are particularly at risk. The following health issues have been associated with AFFF exposure:
- Testicular cancer
- Kidney cancer
- Liver cancer
- Bladder cancer
In addition to cancer, PFAS exposure has been linked to thyroid disease, ulcerative colitis, and other serious health issues.
Potential Mechanisms of Toxicity
PFAS can accumulate in the human body over time, leading to chronic health problems. These chemicals can enter the body through various pathways, including ingestion, inhalation, and dermal absorption. Once in the bloodstream, PFAS can persist for years, potentially contributing to long-term health risks, including cancer.
The Surge in AFFF Lawsuits
As awareness of the alleged health risks associated with PFAS exposure has grown, so too has the number of lawsuits filed against manufacturers of AFFF. According to the latest reports from the U.S. Judicial Panel on Multidistrict Litigation (JPML), the number of pending firefighter foam exposure lawsuits has increased significantly, rising from 9,342 claims in May 2025 to over 10,000 by June 2025. Prominent manufacturers facing firefighter foam lawsuits include:
- 3M Company
- Chemguard
- Tyco Fire Products
These companies are accused of failing to adequately warn users about the potential health risks associated with their AFFF products.
Legal Proceedings and Bellwether Trials
To manage the growing number of firefighter foam claims, the JPML established a multidistrict litigation (MDL) in December 2018. This centralized the lawsuits before a single judge, facilitating coordinated pretrial proceedings. The first bellwether trials are set to begin in October 2025, focusing on representative claims to gauge jury responses.
The outcomes of these initial trials may significantly influence future settlement negotiations. While the results will not be binding on other claims, they could set a precedent for how similar AFFF lawsuits are handled moving forward.
Community Impact and Environmental Concerns
The use of PFAS-containing firefighter foams has not only affected individuals directly exposed to the foam products but has also raised concerns about environmental contamination. Communities near military bases and airports where AFFF was used have reported elevated levels of PFAS in drinking water supplies.
PFAS from firefighter foam can leach into groundwater, potentially contaminating local water supplies and posing health risks to residents. Many affected communities have called for health monitoring and testing to assess the impact of PFAS exposure on public health.
The Future of AFFF Litigation
AFFF lawsuits are being pursued by firefighters, military personnel, and residents who have developed health issues allegedly linked to PFAS exposure. As the number of firefighter foam lawsuits continues to rise, ongoing research into the potential health effects of PFAS and the outcomes of bellwether trials will play a crucial role in shaping future litigation. AFFF manufacturers may opt for settlements to avoid lengthy trials, and increased scrutiny may lead to stricter regulations on the use of PFAS in firefighting foams.
A Call for Awareness and Action
The growing number of firefighter foam cancer lawsuits filed in courts across the country underscores the urgent need for awareness regarding the potential health risks associated with PFAS. As more individuals come forward with legal claims, it is essential for regulators, AFFF manufacturers, and affected communities to address the implications of these toxic chemicals. The ongoing legal battles serve as a reminder of the importance of public health and safety in the face of industrial practices that may have far-reaching consequences.
