Is Fluorine-Free Firefighting Foam Safer than AFFF for Firefighters’ Health?

Key Takeaways:
Fluorine-Free Firefighting Foam (F3) is safer for firefighters compared to Aqueous Film-Forming Foam (AFFF) and plays a crucial role in reducing exposure to harmful PFAS.

Firefighting is an incredibly dangerous profession, exposing firefighters to numerous hazards, from severe burns and smoke inhalation to risks from collapsing structures. One often-overlooked danger is toxic chemical exposure.

When extinguishing fires, firefighters inhale a mix of harmful substances, including formaldehyde, carbon monoxide, benzene, and perfluoroalkyl and polyfluoroalkyl substances (PFAS), commonly found in AFFF, a foam used for Class B fires.

What Is AFFF?

Developed in the 1960s by the U.S. Navy and 3M, AFFF is widely used in both military and civilian settings to combat fires fueled by flammable liquids like jet fuel and gasoline. Its effectiveness comes from surfactants that help the foam spread and suppress flames, but these same surfactants contain PFAS, which pose significant health and environmental risks.

Risks Associated with AFFF

Recent studies have highlighted alarming health risks linked to PFAS, indicating that no level of exposure is considered safe. PFAS exposure has been linked to serious health issues, including various cancers, which contribute to the high cancer rates among firefighters.

Regulatory Actions on AFFF

In response to these concerns, several states have restricted AFFF use in non-emergency situations and during training. Additionally, some states require transparency from manufacturers regarding PFAS in firefighter gear, aiming to empower firefighters to make safer choices.

Is Fluorine-Free Firefighting Foam a Safe Alternative?

Fluorine-Free Firefighting Foam (F3) has emerged as a popular alternative that does not contain PFAS. However, it is essential to consider whether it is entirely risk-free.

Risks Associated with F3

While F3 eliminates PFAS, it may still contain neurotoxic solvents that can lead to symptoms like headaches, dizziness, and long-term neurological issues. Chronic exposure could potentially increase the risk of diseases like Parkinson’s and Alzheimer’s, along with peripheral neuropathy and kidney problems.

F3: A Safer Option

Despite its risks, F3 represents a significant improvement over AFFF. Firefighters are 9% more likely to be diagnosed with cancer and have a 14% higher mortality risk from it compared to the general population. Minimizing toxic exposure is crucial in reducing these statistics, and phasing out AFFF is a positive step.

While F3 is not without health risks, it is a safer alternative. Fire departments should assess health risks carefully and provide training on the proper use of F3 to mitigate exposure.

Exploring Viable Alternatives to AFFF

There are several biodegradable alternatives to AFFF on the market that meet stringent environmental safety standards. As of April 2019, 22 manufacturers offered 90 fluorine-free foams, indicating a global shift toward safer firefighting practices.

However, caution is essential as past misconceptions about AFFF's safety show that not all alternatives are completely free of risks. Ongoing vigilance is necessary when adopting new firefighting technologies to ensure the safety of first responders.

In conclusion, while progress is being made in improving firefighting foam safety, continuous scrutiny and accountability are vital to protect firefighters' health
