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

Non-combustible materials

Labeled with a fire rating

Continuous from floor to underside of roof sheathing

Minimum thickness of 75 mm

A fire-rated wall assembly must meet certain requirements in order to effectively prevent the spread of fire. These include using non-combustible materials, being labeled with a fire rating, and being continuous from the floor to the underside of the roof sheathing. Option D, a minimum thickness of 75 mm, is not a requirement for a fire-rated wall assembly in an industrial building. This may be a common misconception, as thicker walls may provide better fire resistance, but it is not a specific requirement for an industrial building. Therefore, option D is not the correct choice for this question.
