During inspection of a foam concentrate tank, what quantity condition is verified?

• A. The tank is completely full of foam concentrate
• B. The quantity of foam concentrate meets design requirements
• C. The foam concentrate is within its expiration date
• D. The foam concentrate has a visible color change indicator

Answer: (B)

Foam concentrate quantity is checked to confirm the stored amount matches what the system was designed to deliver. The key is having at least the design-required volume so the proportioner can mix the foam properly and provide sufficient foam for the expected duration of operation. The tank does not need to be completely full; it just has to meet the design minimum to ensure reliable performance. Expiration dating and indicators are important for usability, but the question specifically targets whether the quantity aligns with design requirements, which is why this option is the best.
