Sentence 3.2.2.28.(2)

Intent 1:

To exclude a building from the building area limits of Sentence 3.2.2.28.(1) on the basis that the total area does not exceed twice the values of Sentence 3.2.2.28.(1) and that the individual areas are subdivided by a fire separation with a 1 h fire-resistance rating into areas that individually comply with Sentence 3.2.2.28.(1).

Intent 2:

These conditions [fire separation] are to limit the probability that fire will spread within the storey during the time required to achieve occupant safety and for emergency responders to perform their duties, which could lead to damage to the building.
