Stay informed about the design, manufacture, installation, and acceptance testing of water mist fire protection systems using NFPA 750, Standard on Water Mist Fire Protection Systems. This standard describes design, installation, maintenance, and testing requirements for water mist fire protection systems and clarifies applications that benefit from these systems.

Research and technology for water mist fire protection systems are continually evolving, and so is NFPA 750.

Water mist fire protection systems extinguish fires by displacing oxygen through water vapor, cooling the flames and reducing radiant heat. NFPA 750 details general requirements, along with provisions for all types of water mist systems, components, and hardware. To maintain consistency with industry practices and terminology, the 2019 edition updates terms and includes important clarifications that help you understand important concepts, such as:

• Which devices can be used as automatic means
• Which components can be used as provisions for cleaning
• How to apply requirements for pressure-indicating devices used on a common manifold system
• Expanded requirements for listed systems and inclusion of configurations allowed in current listed solutions
• The proper location of the fire department connection (FDC) on a low-pressure water mist system

New sections are added to help you:

• Specify design, testing, and installation of preaction water mist systems
• Prevent debris and contaminants from entering a water mist system by applying requirements for adding a strainer or filter after the FDC

Designers, consumers, AHJs, installers, maintainers, and special experts -- including users from museums and historic preservation societies -- will find the guidance they need in NFPA 750.
