Heat Vents

The Building Code of Australia allows the use of heat vents in buildings to expel heat in the event of an emergency under the building regulations. The use of heat vents provides extra time at floor level for occupants to evacuate the building. The location of heat vents is determined by engineers, and approved by the buildings surveyor/building certifier, who will nominate the heat vents in the building’s essential safety measures determination/ schedule/ schedule essential safety provisions.

Essential Safety Measures Audit – Heat Vents

The building surveyor’s essential safety measures determination will nominate AS 1851-2005 Maintenance of fire protection systems and equipment as the maintenance standard for heat vents. The essential safety measures auditor to ensure fire safety compliance should check the essential safety measures determination for frequency of inspections and review the contractors logbook required under AS 1851 for heat vents. Upon review, any heat vents deficiencies noted should be recorded in the building’s essential safety measures logbook to allow signing the Annual Statement, Annual Certificate Compliance, Annual Fire Safety Statement, Annual Maintenance Statement and Annual Occupiers Statement.
