When building modifications are made in a sprinklered building, NFPA 25 requires the property owner to do what?

• A. Notify the fire department
• B. Evaluate the adequacy of the fire sprinkler system
• C. Replace entire system
• D. Increase testing frequency

Answer: (B)

When changes are made to a sprinklered building, the system’s ability to perform as designed can be affected. NFPA 25 requires the property owner to re-evaluate the fire sprinkler system after modifications to confirm it still delivers the required density, coverage, and flow. This evaluation looks at updated hydraulic calculations, the available water supply, and any new obstructions or changes in sprinkler layouts to ensure protection remains adequate. If the evaluation identifies gaps, corrections or adjustments are made; otherwise no automatic overhaul is mandated. Notifying the fire department, replacing the entire system, or simply increasing testing frequency aren’t automatic requirements tied to building modifications under NFPA 25.
