How often should sprinkler systems be inspected according to NFPA 13?

NFPA 13 requires that sprinkler systems be inspected at least annually to ensure their proper functioning and compliance with safety standards. This annual inspection is crucial as it allows for the detection of potential issues such as corrosion, obstructions, or mechanical failures within the system. Regular inspections help maintain the reliability of the sprinkler system in the event of a fire, which is a primary purpose of these systems.

While more frequent inspections, such as quarterly or semi-annually, may be necessary in certain high-risk environments or depending on specific code provisions or manufacturer recommendations, the minimum requirement set forth by NFPA 13 is an annual inspection. Understanding this timeframe is essential for fire safety professionals to plan their maintenance schedules effectively and ensure that the systems remain in optimal working order.
