Which NFPA standard addresses water mist fire protection systems?

• A. NFPA 409
• B. NFPA 214
• C. NFPA 750
• D. NFPA 307

Answer: (C)

The key idea is recognizing which NFPA standard specifically covers water mist fire protection systems. NFPA 750 is the Standard for Water Mist Fire Protection Systems, and it lays out the design, installation, testing, and maintenance requirements for these systems. Water mist works by releasing very fine droplets that absorb heat rapidly, cooling the fire and helping control it with typically less water damage than traditional sprinkler systems. NFPA 750 provides the criteria to achieve that performance safely across different occupancies and hazards. The other NFPA standards address topics outside water mist systems—such as different fire protection applications or facilities—so they do not govern the design and installation of water mist systems.
