NFPA 25

NFPA 25 is the recurring side of fire protection: the inspections, tests and maintenance that keep an installed sprinkler or standpipe system in service. It is the standard behind quarterly and annual rounds — and the one most often reconstructed from memory at audit time.

Adoption varies by jurisdiction — confirm the edition your authority having jurisdiction enforces before you run a walk against it.

What it covers

  • Inspection intervals for valves, gauges and heads
  • Flow, trip and churn testing
  • Impairment handling and documentation
  • Record retention for each interval

What the evidence looks like

  • Valve positions photographed as found, before anyone touches them.
  • Gauge readings captured in frame rather than written down alone.
  • An impairment photographed at start and at restoration, timestamped both ways.
