What is the maximum distance below the ceiling for storage?

• A. 12 inches
• B. 18 inches
• C. 24 inches
• D. 6 inches

Answer: (B)

In fire safety terms, there’s a required vertical clearance between stored materials and the ceiling to keep sprinkler coverage effective and prevent heat or smoke from being blocked. The maximum distance allowed from the ceiling to the top of stored items is eighteen inches. So, top of storage must be no more than eighteen inches below the ceiling. Distances smaller than that still meet the requirement, but they don’t represent the limit. Distances larger than eighteen inches would exceed the allowed clearance and aren’t permitted; for example, twenty-four inches would be too far and reduce sprinkler effectiveness.
