Fire Isolated Lift Shafts

The Building Code of Australia requires a lift connecting storeys to have a building structure to have certain fire resistance levels including walls, doors, roof and floor if necessary. All building surveyors/ building certifiers will nominate fire isolated lift shafts in the essential safety measures determination/ schedule before occupancy occurs.

Building Code of Australia

Part C2 Compartmentation and Separation in Clause C2.10 Separation of lift shafts sets out the criteria for the type of construction and fire ratings required for fire-isolated lift shafts for the issuing of building permits.

The following illustration depicts the construction requirements for fire isolated lift shafts.

The following is a part extract of clause I1.1 for an Essential Safety Measure (as appeared in BCA 2013) known as fire isolated lift shafts:

Essential Safety Measures Audit – Fire Isolated Lift Shafts

When performing an essential safety measures inspection on fire isolated lift shafts an essential safety measures auditor must be aware of the significance of a number of major safety issues the BCA brought to bear in the design and construction of fire isolated lift shafts to ensure fire safety compliance. Some of these issues are fire doors, emergency lighting, artificial lighting, warning signs, fire-resistance levels, construction joints, fire indices and service penetrations in fire isolated lift shafts.

All of these elements combine to ensure the integrity of fire isolated lift shafts providing all the essential safety measures nominated are maintained to a level that they actually operate to the necessary standard in an emergency. Any non-compliant issues for fire isolated lift shafts should be recorded in the building’s essential safety measures logbook to allow signing of the Annual Statement, Annual Certificate of Compliance, Annual Fire Safety Statement, Annual Maintenance Statement and Annual Occupiers Statement.
