Which practice best supports preventing contamination during transfers at an AFFF facility?

• A. Maintain secondary containment around storage and transfer areas to capture leaks or spills.
• B. Rely on routine housekeeping without containment.
• C. Directly discharge foam concentrate to the surface.
• D. Use open drainage for quick disposal.

Answer: (A)

Preventing contamination during transfers relies on secondary containment that captures leaks or spills around storage and transfer areas. This extra barrier keeps AFFF concentrates from reaching soil, drains, or groundwater, enabling quick containment and cleanup. Using secondary containment is crucial because foam concentrates (which may contain PFAS) are persistent and can migrate through the environment if released. By maintaining secondary containment around the areas where you transfer and store foam, you reduce environmental risk, protect water quality, and support regulatory compliance. The other approaches don’t provide an active barrier: relying on housekeeping alone leaves a potential release uncontained; discharging foam concentrate directly to the surface would contaminate the environment; and using open drainage would allow contaminants to escape with effluent.
