NFPA 750 governs which type of fire protection system?

• A. Standard on Fire Alarm Systems
• B. Standard on Water-Cooling Towers
• C. Standard on Aircraft Hangars
• D. Standard on Water Mist Fire Protection Systems

Answer: (D)

NFPA 750 focuses on water mist fire protection systems. Water mist systems use very fine droplets that absorb heat as they vaporize, cooling the fire and often displacing some of the heat and gases, which can suppress the fire with less water than traditional sprinkler setups. This standard covers the specifics of designing, installing, testing, and maintaining these systems, including nozzle types, droplet size, water supply, piping, and the required water densities for different fire scenarios. That’s why it’s the correct reference when dealing with water mist technology. Other standards address different topics, such as fire alarm systems (NFPA 72) or other equipment and applications, which are not about water mist fire protection.
