Guides by inspection.
What each check involves, who can do it and what to keep on file.
- NFPA 25 inspection schedule: NFPA 25 inspection schedule: every task by frequency
- NFPA 10 extinguisher inspection: NFPA 10 fire extinguisher inspection requirements
What catches people out.
- Fire codes are adopted state by state and city by city, often with amendments. The local fire marshal (the authority having jurisdiction) has the final word on intervals.
- NFPA editions differ: your jurisdiction may enforce an older edition of NFPA 25 or NFPA 72 than the current one.
- Elevator, boiler and backflow rules are set by states, cities and water utilities, so intervals vary.
