Fire Rated Materials Applied To Building Elements

Fire rated materials applied to building elements is a term used in previous building regulations that is still applicable today for existing buildings. Fire rated materials applied to building elements at the time would have been nominated in the essential safety measures determination/ schedule by the building surveyor/ building certifier.

Building Code of Australia

The current Building Code of Australia uses different terms to nominate the same building elements deemed to be fire rated materials applied to building elements. A fire rated materials applied to building elements is required to be constructed identical to the test it was approved under in AS 1530.4-2005 Methods for fire tests on building materials, components and structures – Fire-resistance test of elements of construction.

In specification A2.3 Fire Resistance of Building Elements is Table 1 which contains certain building elements deemed to achieve a specific fire resistance level (fire rated materials applied to building elements). A part extract of Table 1 follows:

The following is a part extract of clause I1.1 for an Essential Safety Measure (as appeared in BCA 2013) known as as fire rated materials applied to building elements:

Essential Safety Measures Audit – Fire Rated Materials Applied To Building Elements

An essential safety measures auditor must understand and be aware of the implications of all fire rated materials applied to building elements in a building that requires a fire-resistance level to ensure fire safety compliance. Not all fire rated materials applied to building elements are obvious, and not all have been nominated in previous essential safety measures determinations or in occupation certificate, certificate of classification, certificate of occupancy and certificate of construction compliance. All fire rated materials applied to building elements defects must be recorded in the 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.
