AUST – Essential Property Services advises that the Building Code of Australia requires penetrations in fire-rated structures (fire protection at service penetrations) to be fire protected. Penetrations (known as essential safety measures) 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/ certifier in the essential safety measures determination/ schedule.
Building Code of Australia
Part C3 Protection of Openings, in clauses C3.12 Openings in floors and ceilings for services, C3.13 Openings in shafts and C3.15 Openings for service installations specify the criteria required to ensure penetrations in fire rated structures is complied with. A building service penetrations though a fire or smoke resisting structures should be fire stopped with the appropriated tested material.
The following part extract from clause I1.1 Safety Measures, covers penetrations in fire rated structures:
Table I1.1 SAFETY MEASURES – BUILDING FIRE INTEGRITY
|Safety measure||BCA provisions for determining standard of performance|
|Fire protection at service penetrations through elements required to be fire-resisting with respect to integrity or insulation, or to have a resistance to the incipient spread of fire||C3.12, C3.13, C3.15|
Essential Safety Measures Audit
An essential safety measures auditor must be aware of the fire stopping products on the market and ensure during the inspection process that any deficiencies are nominated in the buildings essential safety measures logbook.
A number of building surveyors/ certifiers nominate Part 17 of AS 1851-2005 Maintenance of fire protection systems and equipment as the requirements for compliance in inspecting penetrations in fire rated structures.
