For decades, firefighters have been on the front lines, protecting communities from the dangers of fire. However, a hidden danger has emerged in recent years, raising concerns about the potential health risks associated with firefighting foams.
Aqueous film-forming foams (AFFF) are firefighting agents that have been widely used since the 1960s. They are effective at extinguishing flammable liquid fires, including those involving jet fuel and petrochemicals. However, this foam contains PFAS, or “forever chemicals,” that are persistent in the environment and accumulate in the human body due to their longevity.
In this article, we will explore the intricate connection among AFFF, PFAS, and firefighters, delving deep into their interwoven dynamics and implications.
The Role of Firefighting Foam

AFFF suppresses flammable liquid fires, forming a thin film on the fuel surface to prevent vapor release and extinguish the fire. Its swift ability to suppress liquid fires, particularly those involving combustible liquids like petroleum, deems it indispensable in firefighting.
According to NFPA Journal, a study by the Fire Fighting Foam Coalition estimated 10 million gallons of AFFF in the US. Approximately 10% belonged to municipal fire departments. Over 80% was found on military bases, airports, and gas and oil facilities. It highlights the widespread use of these chemicals in diverse sectors.
The extensive utilization of firefighting foams containing forever chemicals has sparked apprehension regarding associated environmental and health hazards. Despite the crucial role these foams play in fire safety, the potential drawbacks of these chemicals demand continuous research. Ongoing efforts in research and development are essential to explore safer alternatives in firefighting practices.

For decades, firefighters have relied on a vital tool in their arsenal, i.e., AFFF. This highly effective agent excels at extinguishing flammable liquid fires, including those involving jet fuel and petrochemicals. However, a dark side to this foam has emerged, raising critical questions about its potential health consequences. The concern stems from the presence of forever chemicals in firefighting foam.
Studies indicate concerning trends among firefighters, with consistently elevated PFAS levels in their blood compared to the general population. Research links exposure to these chemicals to an increased risk of specific cancers. Also, the exposure may compromise the immune system, potentially heightening susceptibility to cancer and other diseases.
These findings have sparked a movement among firefighters seeking justice and recognition of the potential health risks associated with toxic foam exposure. These victims are filing lawsuits against parties like manufacturers, distributors, and government agencies.
In these lawsuits, they claim that the toxic foam is responsible for health conditions like cancer. Through AFFF foam cancer lawsuits, victims contend that responsible parties were aware of potential harm but failed to adequately warn users.
TorHoerman Law notes that AFFF exposure may lead to various cancers, like bladder, breast, colon, kidney, liver, and pancreatic cancers. The related lawsuits commonly involve diagnoses like prostate, testicular, kidney, and pancreatic cancers. These legal actions underscore the diverse spectrum of cancers associated with firefighting foam exposure.
