Bushfire Attack Level Assessment (BAL)

 

What is a BAL

BAL stands for Bushfire Attack Levels and it is an assessment carried out to measure a buildings potential exposure to ember attack, radiant heat and direct flame contact, in a bushfire event.  It is a basis for establishing the requirements for construction to improve protection of building elements from attack by bushfire.   The BAL takes into consideration several factors including the Fire Danger Index, the slope of land, types of surrounding vegetation and its proximity to any building.

 

Construction costs will increase considerably as your BAL increases, therefore getting your BAL wrong could be a considerable costs to you.

 

There are six levels of bushfire attack under the Australian Standard 3959-2009, ranging from low to flame zone; 

 

* BAL-Low - There is insufficient risk to warrant any specific construction requirements but there is still some risk 

 

* BAL-12.5 - Ember attack 

 

* BAL-19 - Increasing levels of ember attack and burning debris ignited by windborne embers together with increasing heat flux between 12.5 and 19 kW m2 

 

* BAL-29 - Increasing levels of ember attack and burning debris ignited by windborne embers together with increasing heat flux between 19 and 19 kW m2 

 

* BAL-40 - Increasing levels of ember attack and burning debris ignited by windborne embers together with increasing heat flux with increased likelihood of exposure to flames

 

* BAL-FZ - Direct exposure to flames from fire front in addition to heat flux and ember attack.

 

Who needs a BAL Assessment?

 

All new residential buildings within a bushfire prone area including additions to buildings within 6 meters of a dwelling within a high bushfire prone area, MUST have the sites BAL assessment provided as part of the supporting documentation for building rules assessment.

 

The Australian Standard and BCA (Building Code of Australia) specifies the requirements for the construction of residential buildings and required outbuildings for a particular bushfire attack level.
