Which NFPA standard provides guidelines for the maintenance of private fire service mains?

The correct choice is based on the NEPA 25 standard, which specifically addresses the maintenance, inspection, and testing of water-based fire protection systems, including private fire service mains. NFPA 25 provides comprehensive criteria for ensuring that these systems operate effectively to deliver water during a fire emergency. Routine maintenance and testing are crucial for the reliability of fire service mains, and NFPA 25 outlines the necessary procedures to assure that these systems remain functional and compliant with safety standards.

In contrast, the other standards mentioned serve different purposes; for example, NFPA 70 pertains to electrical safety and installation, NFPA 10 focuses on portable fire extinguishers, and NFPA 72 deals with the installation, maintenance, and testing of fire alarm systems. Therefore, NFPA 25 is the appropriate reference for guidelines relevant to private fire service mains.
