What is the minimum clearance required under sprinkler heads?

Explanation:
The minimum clearance under sprinkler heads is 18 inches. This space keeps stored materials and other objects from shielding the sprinkler's spray pattern and allows heat to reach the head and water to distribute properly to the area below. In storage areas, pallets or goods should be kept at least 18 inches below the lowest sprinkler head to avoid coverage gaps and ensure effective fire suppression. Choices smaller than 18 inches are not sufficient, while 24 inches exceeds the minimum (the question asks for the minimum).
