Going Fluorine Free – Converting a Legacy AFFF System to Fluorine-Free Foam
Presented by Jeremy Souza, P.E. of Code Red Consultants, LLC
AFFF foam systems have been the standard for ignitable liquid firefighting for the past 40+ years. While an excellent extinguishing agent, the fluorinated compounds in AFFF have come under scrutiny in the past several years, with restrictions or outright bans on its use in many states. Fluorine-free foams have entered the market as replacements for AFFF, but no drop-in replacements exist. This case study looks at one of the first fluorine-free foam systems in New England to replace an existing legacy AFFF system. Differences in how fluorine-free foams work versus AFFF, which directly impacted the basis of design, along with the site-specific challenges that were overcome, will be discussed; along with the challenges that other fluorine-free replacement projects will face and tips to mitigate them.
