What is the minimum clearance required above a sprinkler head in a storage area?

The minimum clearance required above a sprinkler head in a storage area is 18 inches. This spacing is essential to ensure the effective operation of the sprinkler system. Proper clearance allows for adequate water distribution and prevents obstructions that could impede the spray pattern.

If storage items are placed too close to the sprinkler heads, it can cause blockage and limit the effectiveness of sprinklers, leading to inadequate coverage during a fire. This distance is particularly critical in warehouses or other storage facilities where combustible materials may be stored. By maintaining an 18-inch clearance, fire protection systems can operate optimally, promoting safety and compliance with fire codes.
