Exploring the Hidden Dangers of AFFF Exposure for Lungs

Aqueous film-forming foam (AFFF) has long been hailed as a hero in firefighting, effectively smothering flames in emergency situations. However, beneath its lifesaving veneer lies a hidden danger – its adverse effects on respiratory health. 

As firefighters, military personnel, and industrial workers continue to utilize AFFF in high-risk scenarios, concerns about its impact on lung function have escalated. In this article, we will dive into the intricate relationship between AFFF exposure and respiratory risks. We will shed light on the often-overlooked hazards lurking within this firefighting agent.

The Chemistry of AFFF

AFFF typically contains a mixture of synthetic compounds such as fluorosurfactants, fluoropolymers, and solvents. According to ConsumerNotice.org, these chemicals work together to form a stable aqueous film on the surface of flammable liquids, effectively suppressing fires. 

However, the breakdown of fluorinated compounds during firefighting operations releases toxic byproducts into the air, including perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). These compounds have been associated with respiratory issues such as lung inflammation and decreased lung function. 

Understanding the chemical composition of AFFF is crucial for assessing its potential health impacts accurately.

Inhalation Hazards

When AFFF is deployed to combat fires, the mechanical action of spraying generates aerosolized droplets containing AFFF components. These droplets can be inhaled by firefighters and bystanders, leading to respiratory tract irritation and inflammation. 

Additionally, the fine particulate matter released during AFFF deployment can penetrate deep into the lungs, exacerbating respiratory conditions and posing long-term health risks. Proper respiratory protection and ventilation systems are essential for minimizing inhalation hazards during firefighting operations.

Legal Consequences and AFFF Lawsuits

According to TorHoerman Law, a growing number of lawsuits have been filed against AFFF manufacturers. They have been initiated by individuals alleging harm from exposure to the firefighting agent. 

Plaintiffs claim that prolonged inhalation of AFFF vapors and direct skin contact has resulted in respiratory ailments, including asthma, bronchitis, and pulmonary fibrosis. 

As per an April 2024 update from Lawsuit Legal News, around 568 new AFFF claims have been filed in March this year. This brings the total pending number of AFFF lawsuits to 7,738.

The AFFF lawsuit underscores the need for accountability and transparency in the handling and regulation of firefighting foam. Public awareness campaigns and regulatory reforms can help address these concerns and prevent future harm.

Occupational Exposure Risks

Occupational groups with routine exposure to AFFF, such as firefighters and military personnel, face heightened risks of respiratory complications. The repeated use of AFFF in training exercises and emergency response scenarios exposes these individuals to elevated levels of airborne contaminants. 

This increases the likelihood of acute respiratory symptoms and long-term lung damage. Comprehensive training programs and strict adherence to safety protocols are essential for minimizing occupational exposure risks.

Mitigating Strategies and Future Outlook

To address the respiratory risks associated with AFFF exposure, proactive measures are essential. This includes implementing proper ventilation systems in firefighting facilities, providing personal protective equipment such as respirators, and conducting regular health screenings for at-risk populations. 

As noted by Industrial Safety & Hygiene News, workers dealing with AFFF must be provided with appropriate PPE. This includes gloves, face shields, or goggles to prevent splash hazards. Lastly, P2 respirators to filter out harmful particles are also necessary.

Furthermore, ongoing research into alternative firefighting agents and cleaner technologies is crucial for minimizing the adverse effects of AFFF on respiratory health. Collaboration between stakeholders and policymakers is key to implementing effective mitigation strategies and protecting public health.


Does AFFF cause asthma?

While AFFF exposure hasn’t been directly linked to causing asthma, inhalation of its components may exacerbate existing asthma. It can also lead to other respiratory problems due to its potential to irritate the airways and induce inflammation, especially with prolonged exposure.

What happens if you are exposed to AFFF?

Exposure to AFFF can lead to respiratory irritation, skin irritation, and potential long-term health effects due to its toxic components. Inhalation of aerosolized AFFF droplets may exacerbate respiratory conditions, while skin contact can cause irritation or dermatitis.

Is AFFF especially suitable for firefighting?

AFFF is commonly used in firefighting due to its ability to rapidly suppress fires by forming a thin film on flammable liquid surfaces. This cuts off the oxygen supply and extinguishes fires. However, concerns about its environmental and health impacts have prompted the search for safer alternatives.

In conclusion, while AFFF remains a crucial tool in firefighting, its potential impact on respiratory health cannot be overlooked. The chemical composition and deployment methods present significant inhalation hazards, prompting an increase in lawsuits and calls for regulatory reform. 

Occupational groups facing routine exposure require comprehensive protection measures. Moving forward, a concerted effort involving stakeholders, policymakers, and researchers is essential to mitigate risks and explore safer alternatives. 

By prioritizing transparency, accountability, and innovation, we can ensure the well-being of those on the front lines while maintaining effective fire suppression capabilities.
