A building has 15,010 sf of metal decking at the roof level that receives SFRM. How many thickness tests must be taken on the deck?

The number of thickness tests is tied to the deck area, with one thickness test required for every 1,000 square feet or fraction thereof. For 15,010 square feet, you divide by 1,000 to get 15.01, and you must round up to ensure full coverage. That gives 16 thickness tests. This approach ensures the sprayed fireproofing on the metal deck is uniformly thick across the entire area. If you did only 12 tests, you’d be testing only 12,000 square feet and leaving a significant portion unchecked. The higher options would exceed the minimum necessary given the rule, so 16 is the correct minimum.
