What is a Bushfire Attack Level (BAL) and why do I need one?

A Bushfire Attack Level (BAL) is one of 6 levels applied to a building to measure the severity of a buildings exposure to bushfire attack. The BAL levels – Low, 12.5, 19, 29, 40 and FZ – are measured in radiant heat flux (kW/m2) and are determined after an assessment process in accordance with Australian Standard 3959. A site inspection is completed to determine separation, slope and vegetation classification to compare with AS3959 matrix to determine a Bushfire Attack Level (BAL).

The Australian Standard provides specific construction requirements to be completed on a building or structure that reflects the severity of risk to a bushfire including ember attack. Generally, a Bushfire Attack Level Report & Certificate from an accredited assessor is required before construction of a building or structure in a bushfire prone area.

Contact one of our accredited bushfire assessors for advice on whether you are located in a bushfire prone area or your project is exempt from meeting this standard on 0411 648 159 or via e-mail at admin@specialisedbuildingsolutions.com
