Towards Eco-Friendly Firefighting: The Growing Need to Find AFFF Alternatives

Towards Eco-Friendly Firefighting: The Growing Need to Find AFFF Alternatives

Fires have become a common occurrence in the US. According to the National Fire Protection Association (NFPA), around 1.5 million fire incidents were reported in 2022. These fires resulted in 3,790 deaths and 13,250 injuries. Moreover, these fires have resulted in billions in damages.

Firefighting has always been a crucial aspect of preserving life and property. Over the years, various techniques and materials have been developed to combat fires effectively. Aqueous Film Forming Foam (AFFF) has been a staple in firefighting.

However, as environmental consciousness grows, concerns about the ecological impact of AFFF have emerged. This article explores the need for eco-friendly firefighting solutions and the search for viable alternatives to AFFF.

The Environmental Impact of AFFF

AFFF contains per- and polyfluoroalkyl substances (PFAS), synthetic chemicals known for their durability and water-resistant properties. PFAS have been linked to numerous health and environmental concerns, including bioaccumulation in wildlife and potential risks to human health.

These chemicals persist in the environment for extended periods, leading to widespread contamination of water sources and ecosystems. The use of AFFF in firefighting operations, training exercises, and accidental releases has contributed to PFAS contamination in soil and water bodies.

Studies have detected elevated levels of PFAS in groundwater, surface water, and even drinking water sources. A Nature Journal study shows that drinking water levels of PFAS have increased. This has further increased PFAS levels in human blood, which exceeds 100 times on average.

The Impact of AFFF on Human Health

The primary ingredients of AFFF are PFAS, which are known carcinogens and can induce toxicity. An NCBI study states that even 1/10th of the actual working environment’s PFAS exposure can significantly alter cellular proliferation.

PFAS has been associated with various adverse health effects, including cancer, immune system dysfunction, liver damage, and developmental issues. These chemicals can accumulate in the body over time, leading to long-term health risks.

Exposure to AFFF can occur through inhalation, ingestion, or skin contact during firefighting operations, training exercises, or accidental releases. Firefighters, military personnel, and individuals living near military bases or airports where AFFF is commonly used may face increased exposure to PFAS.

Firefighters are constantly exposed to AFFF. Therefore, many firefighters have developed several types of cancers and other health issues due to this exposure. However, they have raised their voice for justice.

According to TruLaw, the firefighters allege they were unaware of the potential health problems. Thus, they didn’t have all the data to make an informed decision. Therefore, they seek justice in compensation for the damages they have suffered.

Anyone who has been diagnosed with cancer after AFFF exposure can file an AFFF lawsuit. The lawsuit will help manufacturers and distributors of PFAS products liable for the damages. You can connect with an attorney to support you throughout the legal proceedings.

The Need for AFFF Alternatives

The urgency of finding AFFF alternatives is underscored by the widespread use of AFFF in military, industrial, and commercial settings. This widespread use has contaminated groundwater and drinking water sources in numerous communities.

The detection of elevated PFAS levels in water supplies near firefighting training areas, airports, and manufacturing facilities has prompted calls for action. The goal is to mitigate further environmental damage and protect public health.

Efforts to develop AFFF alternatives focus on identifying compounds that effectively suppress fires while minimizing environmental and health impacts. Research initiatives explore various foam formulations, including fluorine-free, protein-based, and surfactant-based, as potential substitutes for AFFF.

Challenges in Finding Suitable Alternatives

Finding suitable alternatives to AFFF presents several challenges stemming from firefighting agents’ unique properties and performance requirements. These challenges include addressing the effectiveness, environmental impact, regulatory compliance, and cost considerations associated with alternative formulations.

One of the primary challenges is ensuring that alternative foams are as effective as AFFF in extinguishing flammable liquid fires. AFFF’s ability to rapidly suppress fires while forming a durable film to prevent reignition sets a high benchmark for alternative formulations. 

Developing alternatives that match or exceed AFFF’s performance requires extensive testing and optimization of foam compositions, additives, and application methods.

Regulatory compliance presents a significant hurdle in developing and deploying AFFF alternatives. Regulatory frameworks governing fire fighting agents’ use, storage, and disposal vary by jurisdiction. They may impose stringent requirements on chemical composition, toxicity, and environmental persistence.

Navigating these regulatory requirements while ensuring that alternative formulations meet performance standards adds complexity to the research and development process.

Promising Alternatives to AFFF

Several promising alternatives to AFFF are currently under investigation and development:

  • Fluorine-Free Foam (F3): Fluorine-Free Foam formulations offer firefighting capabilities without relying on PFAS chemicals. These foams utilize alternative surfactants and additives to suppress fire while minimizing environmental harm. F3 has effectively extinguished various types of fires, including hydrocarbon and polar solvent fires.

F3 has been the most efficient in suppressing fires after AFFF. Although it is not as effective, it comes very close. According to NFPA, the U.S. Department of Defense has spent around $28 million researching effective F3.

  • Protein foam: Protein-based foams derived from natural sources such as animal proteins offer an eco-friendly alternative to AFFF. These foams form a stable blanket over the fire, preventing oxygen from reaching the fuel source. Protein foam formulations are biodegradable and have shown promising results in extinguishing Class A fires involving organic materials.
  • High-expansion foam: High-expansion foams generate large volumes of foam with minimal water usage. This makes them suitable for firefighting in confined spaces and areas with limited access. These foams are often used in industrial settings and confined spaces where traditional firefighting methods are impractical.

The expansion process of high-expansion foam is achieved by introducing air into a water and foam concentrate solution. This creates bubbles within the solution, causing it to expand dramatically in volume. The foam’s expansion ratio can vary depending on the formulation and application requirements but generally ranges from 200 to 1000 times its original volume.

  • Dry chemical agents: Dry chemical agents, such as potassium bicarbonate and monoammonium phosphate, offer an effective alternative to AFFF for combating Class B and Class C fires. These agents chemically interrupt the combustion process, making them versatile options for fire suppression in various environments.

To conclude, the growing need for eco-friendly firefighting solutions underscores the urgency of finding effective, sustainable, and safe alternatives to AFFF. This is essential for the environment and human health.

While significant challenges lie ahead, ongoing research and collaboration offer hope for a future where firefighting practices align with principles of environmental responsibility. By embracing innovation and adopting eco-friendly alternatives, the firefighting community can mitigate the ecological impact of firefighting operations.
