Multiple Choice

Storage and all obstructions should be no closer than __________ inches to sprinkler heads.

Explanation:
Maintaining a clear zone around sprinkler heads is essential for the head to discharge water where needed and for heat to reach the deflector promptly. The minimum distance for storage and obstructions is 18 inches, measured from the face of the sprinkler head to the nearest obstruction. Keeping items such as pallets, racks, or boxes at least this far away prevents blocking or deflecting the water spray, avoids creating dead zones, and reduces shielding of the head from heat. If items encroach closer, the sprinkler may not cover the protected area effectively, increasing fire growth and damage.
