What type of inspections does NFPA 25 require for spare sprinklers?

NFPA 25, which governs the inspection, testing, and maintenance of water-based fire protection systems, mandates that spare sprinklers undergo both operational and visual inspections.

Operational inspections ensure that any stored spare sprinklers are functional and maintain their ability to operate effectively should they need to be deployed. This involves verifying that the sprinklers are the correct type and that there are no damages that may hinder their performance.

Visual inspections, on the other hand, allow technicians to assess the physical condition of the spare sprinklers. This includes checking for any signs of corrosion, structural integrity, or obstructions that could prevent the sprinklers from functioning as intended.

By requiring both types of inspections, NFPA 25 emphasizes a comprehensive approach to ensuring readiness and safety in fire protection systems. This dual requirement supports the overall goal of maintaining an effective and reliable fire protection system, ensuring that all components are in optimal condition when needed.
