What minimum distance must a sprinkler maintain from an obstruction?

• A. 1 ft
• B. 2 ft
• C. 3 ft
• D. 4 ft

Answer: (C)

Sprinkler spray must stay unobstructed so the water can reach the protected area. To ensure the water pattern isn’t blocked or deflected by nearby objects, a clearance of three feet between the sprinkler and any obstruction in the spray path is required. If an obstruction sits closer than three feet, it can interrupt the spray and create an unprotected zone beneath it. Distances smaller than three feet don’t provide enough clearance, while four feet goes beyond the minimum and isn’t required by the standard. The measurement is from the deflector to the nearest obstruction in the plane of the spray.
