Research statistics have indicated that over 85% of homes destroyed during a bushfire, is a direct result of ember attacks.
Ember attack occurs when burning debris (e.g. twigs, branches, leaves) is carried by winds in a cluster. Embers can range from tiny sub-millimetre sparks to large inch sized chunks, which lodge in gutters, get under doorways, enter roof spaces or windows and start internal fires. The movements of embers from a bushfire are the primary cause of spot fires, which contribute to the continued spread of a bushfire.
All new homes built in bushfire prone areas must comply with the Australian Standard AS 3959-2009 and AS 3959-2009/AMDT 2011 Construction of Building in Bushfire Prone Areas. This standard is primarily concerned with improving the ability of buildings in designated bushfire prone areas to better withstand an attack from bushfires, giving a measure of protection to the people inside as well as to the building itself.
To ensure that your home complies with the above legislative requirements you should check with your local council to find out whether your property is within a designated bushfire prone area and the correct, current Bushfire Attack Level (BAL) and take proactive steps to protecting your home. This also includes established homes that are being modified or extended.
