According to NFPA 25, sprinklers should be inspected for corrosion and damage at what intervals?

Sprinklers are critical components of fire protection systems, and NFPA 25 outlines the guidelines for inspecting them to ensure they are functional and reliable. According to these standards, sprinklers should be inspected for corrosion, damage, and other issues annually. This yearly inspection allows for the early identification of any potential problems that might impair the sprinkler system's performance in a fire emergency.

Regular inspections are essential as they help maintain compliance with safety regulations and ensure that the system will operate effectively when needed. Inspections are not conducted more frequently, such as quarterly, because that would impose an unnecessary burden on resources without significant added benefit in most scenarios. Similarly, extending the interval to every two years or five years increases the risk that any issues might go unnoticed for too long, potentially compromising safety in a fire situation. Therefore, the annual interval established by NFPA 25 strikes the right balance between thoroughness and practicality.
