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

  1. Non-combustible materials

  2. Minimum thickness of 100 mm

  3. Labeled with a fire rating

  4. Continuous from floor to underside of roof sheathing

The correct answer is: Continuous from floor to underside of roof sheathing

A fire-rated partition in a commercial building must be made of non-combustible materials, have a minimum thickness of 100 mm, and be labeled with a fire rating. However, it does not necessarily need to be continuous from floor to underside of roof sheathing. Non-continuous fire-rated partitions may be used if it meets specific conditions and is approved by the building code or fire code authority.
