Intent | 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 harm to persons. |
