Important Update Regarding Firefighting Foams
In recent years, regulations surrounding the use of firefighting foams, particularly AFFF (PFAS) foams, have evolved due to their environmental and health risks. These foams are now recognised as persistent environmental pollutants.
Following directives from DEFRA (Department for Environment, Food and Rural Affairs), the HSE (Health & Safety Executive) has engaged with the industry to assess the prevalence of AFFF foams in fire safety systems. For more details, refer to the UK REACH – PFAS firefighting foams call for evidence on the HSE website.
Key Regulatory Changes
- C8 AFFF Foam: Already prohibited due to its structure containing 8 carbon atoms. Systems with this foam should be replaced as soon as possible.
- C6 AFFF Foam: Contains 6 carbon atoms and is expected to be banned by 2030. Restrictions on sales may begin as early as 2025, impacting both new systems and replacements in existing systems.
Your Options
The Fire Protection Association (FPA) has issued guidance on transitioning to a new type of firefighting foam, SFFF (synthetic fluorine-free foam). However, replacing old foam with SFFF is not straightforward:
- Testing and Effectiveness: SFFF has not been widely tested and has shown to be less effective than AFFF. This necessitates a design review of existing systems to ensure compatibility.
- System Adjustments: New sprinkler heads compatible with SFFF may be required. Existing heads can be tested for compatibility. Due to the lower effectiveness of SFFF, more water may be needed, potentially requiring larger pipes, pumps, and water storage tanks.
Mitigating Challenges
Through consultation, several approaches can be considered to address these challenges, including adjusting risk profiles and storage arrangements.
