Choosing a Firefighting Foam That is PFAS-Free

 

In the U.S., firefighters have two choices when it comes to firefighting foams: Class A and Class B. Class A extinguishes fires involving paper, wood, and brush, while Class B is commercial surfactant solution used to fight flammable vapors. Both types of foams are produced by commercial companies and may be stored in a local fire department's inventory.

PFAS chemicals can cause a wide variety of health issues. Thankfully, there are several alternatives available to these toxic ingredients. PFASs have been identified as the main cause of cancer and birth defects. However, they remain dangerous to humans and are banned in some countries. For this reason, it is important to choose a foam that is PFAS-free. Fortunately, there are several companies working toward eliminating PFASs in the firefighting industry.

PFASs are hazardous to firefighters. Not only are they exposed to AFFFs during training and fires, but their firefighting gear is also contaminated. Researchers at Biomonitoring California found that PFOS levels were high in the firefighting gear used by firefighters. Fortunately, there are greener alternatives for firefighters. Several manufacturers of firefighting foam are committed to this goal. This certification program will ensure that they meet the standards.

EPA is working to establish an AFFF take-back program. It is also evaluating disposal options and developing best management practices for Class B firefighting foam. The agency is also working with stakeholders to identify impacted media and wells and to ensure that water supplies are kept safe. This is a vital part of firefighting. So what can you do? Let US Ecology help you! It is your best bet to help protect our environment from PFASs.

PFASs are banned in the U.S., but they are still in use. Despite the fact that PFASs are environmentally harmful, they can be used to protect buildings from fires. The state of New Hampshire has a takeback program for PFASs and is working on a PFASs waste recycling program. Its website includes more information on the takeback program. Just as important, the NHDES will be monitoring the process to ensure that it is adhering to the law.

The process of using foam is different in each type. When it comes to liquids, it is better to use foam that has a long-lasting effect. Those with a short-term firefighting solution should avoid using a chemical FirefightingFoam. Aqueous film forming foam is used to fight flammable liquid fires. It can be purchased as a concentrate and is commonly referred to as Type 3 or 6.

While many chemicals used in firefighting foam are PFASs, aqueous film forming foam is a popular choice for firefighters. While it has a proven track record, it is still a relatively new option in the U.S. Due to rising liability risks and health concerns, it may be wise to consider using PFAS-free foams. The only real way to know if a flammable liquid is a PFAS is to read the label.
