NFPA 25
Baseline ITM framework for water-based fire protection systems. Focuses on keeping systems reliable through scheduled inspection, testing, maintenance, documentation, and impairment management concepts (high level).
Many sprinkler and water-based failures are preventable: valves left closed, impairments unmanaged, testing skipped, or documentation missing. A consistent ITM program turns system reliability into a managed routine.
- Inspection/testing/maintenance program structure concepts (high level)
- Documentation and reporting concepts
- Impairment management and corrective action concepts
- Roles and responsibilities concepts (owner, contractor, authority) (high level)
- Reliability-focused scheduling concepts
- Coordination concepts with fire watch and interim risk controls (high level)
- Facility ITM calendars and compliance documentation
- Valve supervision and impairment tracking programs
- Reducing nuisance events and improving reliability before incidents
- Fire watch planning during system outages or impairments
- Sprinklers are ‘set and forget’ (valves/impairments cause many failures).
- Passing one test means the system is reliable (reliability is continuous).
- Documentation is bureaucracy (it proves readiness and drives fixes).
- Create a one-page impairment workflow: notify → mitigate → track → restore
- Standardize valve checks and document them in a repeatable format
- Keep a simple dashboard for overdue ITM tasks and closed impairments
- Use fire watch logs when interim measures are required
