What is the typical shelf life practice for foam concentrate at a transfer station?

• A. Use oldest first and discard expired items only after 1 year.
• B. Rotate stock monthly; keep a simple log.
• C. Shelf life is not applicable; store indefinitely.
• D. Follow the manufacturer's shelf life; rotate stock, discard expired; maintain inventory log.

Answer: (D)

Foam concentrate shelf life is defined by the manufacturer and how the product is stored, so you manage it by following that specified shelf life and keeping good records. At a transfer station, rotate stock using first-in, first-out to use older lots first, discard any product when it has reached its expiry date, and maintain an inventory log that tracks lot numbers and dates. This approach protects performance, supports traceability, and helps prevent using expired concentrate. Other approaches fall short because they either rely on a universal fixed time that may not apply to all products, assume shelf life doesn’t apply at all, or don’t require documenting dates and lot information, which can lead to using degraded concentrate or losing track of expiration.
