Sprinklers shall be inspected from which level and at what frequency?

• A. From the floor level monthly.
• B. From the floor level annually.
• C. From the ceiling level annually.
• D. From the ground level biannually.

Answer: (B)

Visual inspection of sprinklers is done by looking up at each head from the floor to verify there’s nothing nearby or on the head that could block discharge. Doing this from floor level lets you clearly see the sprinkler head and its surrounding area, checking for obstructions, paint, corrosion, or damage that could impair performance. The annual frequency matches standard practice for this kind of routine visual check—frequent monthly checks aren’t necessary for head-level inspection, and biannual or other less frequent schedules would allow issues to go unnoticed too long. Inspecting from the ceiling isn’t practical for a quick, routine review, and ground level would be effectively the same as floor level but isn’t the stated method.
