Which of the following is not a requirement for a fire-rated floor-ceiling assembly in an industrial building?

Non-combustible materials
Labeled with a fire rating
Continuous from wall to wall
Minimum thickness of 75 mm

The correct answer is: Minimum thickness of 75 mm

A minimum thickness of 75 mm would actually be a requirement for a fire-rated floor-ceiling assembly in an industrial building. Non-combustible materials, a labeled fire rating, and being continuous from wall to wall are necessary requirements for a fire-rated floor-ceiling assembly. Choosing D would be incorrect because it is actually a requirement rather than not being one.
