What type of systems are covered in NFPA 25 Chapter 12?

NFPA 25 Chapter 12 specifically addresses Water Mist Systems, which are an important fire protection strategy. This chapter outlines the inspection, testing, and maintenance requirements for these systems to ensure their effectiveness in controlling or suppressing fires. Water mist systems utilize fine water droplets that can significantly enhance cooling and reduce the thermal load, making them effective in certain applications where traditional sprinkler systems may not suffice. Understanding the regulations in Chapter 12 is crucial for professionals involved in the ITM of these systems, as adhering to the guidelines helps ensure that these innovative fire protection measures operate as intended.

The other options do relate to fire protection systems but are governed by different chapters within NFPA 25, which is why they do not fall under Chapter 12's scope.
