Which NFPA standard applies to a private water supply for an industrial building?

The applicable NFPA standard for a private water supply for an industrial building is NFPA 13. This standard specifically addresses the design and installation of sprinkler systems, which are essential in fire protection for various types of buildings, including industrial facilities. NFPA 13 outlines the requirements for water supply systems, including private water sources necessary to ensure that the sprinkler systems can operate effectively during a fire incident.

This standard ensures that the water supply is adequate in terms of both quantity and pressure, which is critical for the proper functioning of fire sprinkler systems. It also includes provisions for the design, maintenance, and inspection of these systems, making sure that they can provide the necessary protection when called upon.

In contrast, the other options focus on different aspects of fire protection. NFPA 12 deals with carbon dioxide extinguishing systems, NFPA 25 covers the inspection, testing, and maintenance of water-based fire protection systems, and NFPA 14 pertains to standpipe and hose systems. While all these standards are important within the larger fire protection framework, they do not specifically address private water supply requirements for fire sprinkler systems within industrial buildings.
