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

  1. Non-combustible materials

  2. Labeled with a fire rating

  3. Continuous from wall to wall

  4. 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.
