What is the shelf life of AFFF?

Aqueous Film-Forming Foam (AFFF) is designed to have a long shelf life, which is critical for emergency response equipment. When properly stored in sealed containers, AFFF can remain effective for an extended period, often reported as indefinite. This characteristic is vital for ensuring that the foam remains usable when needed, especially in emergency situations where reliability is crucial.

The indefinite shelf life is contingent on maintaining proper storage conditions—keeping it away from extreme temperatures and direct sunlight, for example. While some products may have specific expiration dates influenced by their chemical composition or intended use, in the case of AFFF, manufacturers often outline that it can be stored for a very long time without losing effectiveness, assuming no contamination occurs.
