Flushing shall be performed in accordance with which standard?

Flushing shall be performed in accordance with which standard?

• A. NFPA 24
• B. NFPA 13
• C. NFPA 25
• D. NFPA 70

Answer: (A)

The key idea is that flushing concerns cleaning the private fire-service main and its appurtenances before the system operates. NFPA 24 covers the installation and testing of private service mains and their appurtenances, including procedures to flush the line to remove debris and contaminants so the water supply to the foam-water system is clean and reliable. This is the standard that governs how the service line itself is prepared prior to system activation. NFPA 13 deals with sprinkler design and installation more broadly, not the private service main flushing. NFPA 25 focuses on inspection, testing, and maintenance of water-based systems after installation, not the initial flushing during installation. NFPA 70 is the electrical code, which isn’t applicable to flushing the water supply.
