Firefighter Foam Ban: Potential Impact on Wildfire Suppression Strategies

Firefighters are the front-line heroes in the fight against wildfires. They risk their own safety to protect both communities and natural habitats from destructive wildfires. However, their bravery is frequently met with unexpected dangers. Concerns have emerged over Aqueous film-forming foam, a popular firefighting agent, due to its health and environmental risks. A proposed ban on certain AFFF types questions future wildfire fighting effectiveness.

The Ban on Firefighting Foams

The European Chemicals Agency has proposed an EU-wide restriction on all PFAS-based firefighting foams. This move aims to prevent soil and groundwater contamination, as well as health concerns for people and the environment. The United States Department of Defense has also mandated that PFAS-based firefighting foams should be discontinued by October 1, 2023. It must be completely phased out by October 1, 2024.

The proposed ban has resulted in a surge of firefighter foam lawsuit cases. More than 7,000 cases are pending in the United States District Court for the District of South Carolina. These lawsuits claim that exposure to the toxic chemicals in firefighting foam has caused serious illnesses, including cancer.

The Impact of the Firefighting Foam Ban on Wildfire Suppression

Firefighting foams have been incredibly effective at fighting fires, especially those not extinguished with water alone. Therefore, the ban on firefighting foams could have significant implications for wildfire suppression strategies. It would necessitate the search for alternatives that are equally effective but without the associated health risks.

A recent study suggests that fire suppression, including the use of firefighting foams, can make wildfires more severe. It also emphasizes the impact of fuel accumulation and climate change. The study argues that suppression may significantly influence fire patterns globally.

Alternative Wildfire Suppression Strategies

In light of the proposed ban, fire managers must consider alternative fuel management actions. They can opt for the following strategies:

1. Prescribed Fire

This is a planned fire meant for management objectives. It involves the controlled application of fire by a fire experts team under defined weather conditions. Appropriately timed and located fires can reduce the risk of hazardous fuels. It can also save communities from severe wildfires, and restrict the spread of insects, pests, and diseases. Additionally, benefits are noted in the growth of trees and the expansion of wildflowers and diverse plant life.

Research highlights the effectiveness of prescribed fire as a cost-efficient alternative to wildfire suppression. This can incur costs exceeding $2 billion annually in the U.S. alone. However, the implementation of prescribed burns faces several barriers, including a prevailing fire management culture that favors suppression over prevention. The responsible team can face a lack of resources for prescribed fire projects, and regulatory and liability issues.

2. Mechanical Treatments

This strategy involves the use of machinery or other equipment to physically alter the landscape. Specific methods can vary greatly based on the context. Mechanical treatments often include activities like mowing, chipping, or mulching vegetation to reduce fuel loads and mitigate fire risk.

3. Grazing

The strategy involves the use of livestock to consume vegetation and reduce the availability of fuel for wildfires. Different methods of grazing include continuous grazing, set stocking, rotational grazing, and management-intensive grazing. Each of these affects animal productivity and pasture health.

4. Landscaping

Landscaping plays an important role in wildfire suppression strategies, with the strategic arrangement of both built and natural elements. The strategy enhances a property’s resilience against wildfire threats. Effective landscape design improves the aesthetic and functional aspects of an environment. This involves creating defensible spaces that act as buffers to slow or stop the spread of fire toward structures.

The concept of defensible space divides a property into zones, with specific guidelines focusing on vegetation management to reduce wildfires. The closest zone to your home emphasizes removing highly combustible materials and replacing them with non-combustible options. Substances like gravel, pavers, or concrete are usually preferred. Also, ensure roofs, gutters, and decks are clear of debris that can ignite from embers.

Each strategy has benefits and challenges. The best approach often involves a combination of these strategies tailored to the area’s specific conditions and needs.

Frequently Asked Questions

What is the issue with firefighting foam?

Firefighting foam containing PFAS can pollute groundwater and drinking water reserves, and expose firefighters to PFAS. Recent research has discovered that PFAS in firefighting foam is a probable human carcinogen. It is associated with prostate, testicular, bladder and kidney cancer.

What kind of firefighting foam is most effective for combating wildland fires?

For wildland fires, Class A Foam is the preferred choice. It’s designed for extinguishing Class A materials like wood, paper, and brush. Hence, it’s a go-to for many fire departments in both wildland and structural fire scenarios. This substance is applied as a foam-water combination or through a compressed air foam system and typically lacks PFAS chemicals.

Does AFFF foam pose a risk to health and safety?

AFFF is considered hazardous by the U.S. Occupational Safety and Health Administration due to its several health hazards. It irritates the skin and eyes. The Clean Water Act controls AFFF discharge on land, at sea, and into surface waters. It also applies to wastewater and runoff.

What will replace AFFF foam?  

GFFF is a fluorine-free foam alternative to AFFF and the safe firefighting foam for firefighters. GreenFire® Firefighting Foam (GFFF) falls under the category of class B foam. Yet, it is not carcinogenic or toxic.

According to TorHoerman Law, addressing the challenges posed by AFFF requires a strong integrated approach. Firefighters, environmental regulators, foam manufacturers, and research institutions should join hands to investigate the matter. The proposed ban on AFFF underscores the urgent requirement for developing effective and safe options. R&D initiatives are underway to produce PFAS-free firefighting foams that offer comparable performance to AFFF.
