Question: 1 / 400

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

Non-combustible materials

Labeled with a fire rating

Continuous from wall to wall

Minimum thickness of 75 mm

A and B are both requirements for a fire-rated ceiling assembly. Non-combustible materials are necessary to prevent the spread of fire, while a fire rating label ensures that the ceiling has been tested and approved for its level of fire resistance.

C is also a requirement, as any gaps or breaks in the ceiling can compromise its fire protection capabilities. Therefore, D is the only incorrect option as there is no minimum thickness requirement for a fire-rated ceiling assembly.
