Where does NFPA 16 require foam concentrate storage to be located?

• A. In a safe, accessible location with proper ventilation and spill containment
• B. In the main water supply room
• C. Adjacent to ignition sources
• D. In a sealed, unventilated area

Answer: (A)

Foam concentrate storage must be in a safe, accessible area that provides proper ventilation and spill containment. NFPA 16 requires a dedicated storage location (room or cabinet) designed for chemical storage, with ventilation to control vapors and spill containment to prevent releases from reaching the environment or other systems. This setup also keeps the concentrate away from ignition sources and heat, reducing fire and explosion hazards and protecting the integrity of the concentrate. Storing in the main water supply room, next to ignition sources, or in a sealed, unventilated area would not meet these requirements, so the recommended location is a ventilated, accessible area with spill containment.
