Trending State PFAS Bans

In July 2020, firefighting foam containing PFAS (per- and polyfluoroalkyl substances) was banned for sale within the State of Washington (Senate Bill 6413).* This was the first state ban that impacted firefighting foam systems utilizing fluorine-based foam, including AFFF (Aqueous Film Forming Foam). Since then, additional states have banned or restricted PFAS-containing foam systems and products. Recent bans and legislation are listed below.

AFFF is commonly used in facilities to suppress high-hazard flammable liquid fires like jet fuels and gasoline. The presence of PFAS requires these systems to be replaced.

A discharge incident could result in significant business disruption and a potential release of PFAS contaminants to the environment. A discharge incident could be inadvertent (more likely), or due to fire. Also, and more importantly, if your facility is following NFPA and/or insurance requirements for annual testing, this can use up foam concentrate, leaving the system impaired without a discharge incident. The system could be impaired for a significant amount of time without the ability to purchase replacement foam.

Assessing your system in advance may prevent unexpected shutdowns or delays

Each facility’s equipment, hazards, and business operations are unique. If your facility utilizes foam containing PFAS, Coffman recommends performing a foam system replacement study to review the current foam system design and hazards protected. This study will help to inform decisions on cost-effective system replacement options that can protect your facility and reduce business disruption.

CASE STUDY: AFFF Replacement Results in Cost Savings for Puget Sound Energy (PSE)

Coffman was engaged by Puget Sound Energy (PSE) to review replacement options for an existing AFFF foam-water sprinkler system at their South King Center facility. Coffman determined that the hazards protected by the existing system could be protected with a water-based fire suppression system utilizing an alternate means and method, which was accepted by the local Fire Marshal.

Replacing an existing foam-water sprinkler system with water-based fire protection is not a solution for all hazards, however, this solution saves PSE on the cost associated with the system replacement and future costs associated with system maintenance.
