Which NFPA standard covers the inspection, testing, and maintenance of water-based fire protection systems?

The correct choice is NFPA 25, which specifically outlines the requirements for the inspection, testing, and maintenance of water-based fire protection systems such as sprinklers, standpipes, and fire pumps. This standard ensures that these critical systems remain functional and effective in protecting lives and property from fire hazards.

NFPA 25 provides criteria for the frequency and types of inspections and tests that should be conducted, as well as the maintenance procedures that need to be followed to ensure that the systems perform as intended. This includes guidelines for annual tests, inspections after system alterations, and necessary maintenance to maintain compliance and the reliability of the systems.

Understanding the importance of NFPA 25 helps ensure that fire protection systems are properly maintained and reduces the risk of system failure during emergencies.
