What is a primary safety objective of keeping foam concentrate storage separate from the water supply?

• A. To simplify installation
• B. To prevent contamination of potable water or sprinkler water
• C. To increase foam density
• D. To reduce supply line pressure

Answer: (B)

Preventing cross-contamination of the water supply is the main safety goal when foam concentrate storage is kept separate. Foam concentrates can contain chemicals that, if they backflow or leak into potable water or sprinkler water, may compromise drinking water quality and/or the effectiveness of the foam treated water. Separation reduces the risk of any contaminated concentrate entering the water system, often reinforced by backflow prevention and dedicated transfer piping. The other options don’t address safety: simplifying installation, changing foam density, or altering supply pressure don’t target the risk of contaminating the water supply.
