If the foam concentrate bladder is replaced and no foam concentrate is onsite, within how many hours should a reserve supply be delivered?

• A. 48 hours
• B. 24 hours
• C. 72 hours
• D. 1 week

Answer: (B)

After replacing the foam concentrate bladder, you should have a reserve supply delivered within 24 hours. This quick replenishment keeps the fixed foam system ready to operate without delay if the bladder replacement coincides with a discharge, testing, or maintenance need. Waiting longer—such as 48 hours, 72 hours, or a week—creates a gap during which the system might not have the necessary concentrate, compromising readiness and protection. Ensure the reserve is the correct type and stored per guidelines so it remains usable when needed.
