Which of the following NFPA codes is concerned with inspections and maintenance?

The National Fire Protection Association (NFPA) code that addresses inspections and maintenance is NFPA 25. This code specifically focuses on the maintenance, testing, and inspection of water-based fire protection systems, such as sprinkler systems and standpipes. It provides guidance on the frequency of inspections, testing methods, and maintenance requirements to ensure that these systems function properly in the event of a fire.

NFPA 25 is critical for fire safety as it helps ensure that fire protection systems are in optimal working condition, which can significantly mitigate fire hazards and improve overall safety in buildings.

In contrast, NFPA 101 deals with life safety in occupancy, establishing requirements to protect people from fire and similar emergencies, while NFPA 5000 outlines the building construction and safety principles for various types of buildings. NFPA 704 provides a way to identify the hazards associated with materials through a labeling system, focusing more on chemical safety than on inspections or maintenance.
