Penetrations in Fire Rated Structures
The Building Code of Australia requires penetrations in fire rated structures (fire protection at service penetrations) to be fire protected. Penetrations through elements requiring a fire resistance level (i.e. fire walls, floors, shafts, ceilings) must maintain the integrity of the building element requiring that fire-resisting level. All penetrations in fire rated structures would be nominated by the building surveyor/building certifier in the essential safety measures determination/ schedule.
