This YouTube video from the "Irfan CFPS" channel provides an introduction to NFPA 13, a standard governing the installation of sprinkler systems. The video discusses the purpose and goal of the standard, which aims to ensure proper design and installation of sprinkler systems to protect life and property from fire. It also explores key definitions used in the standard and outlines the five critical components for proper design and analysis of a sprinkler system: water supply, hazard selection, design approach, system components, and installation. The video concludes by previewing the next class, which will focus on the types of water supplies acceptable under NFPA 13.
