Short Fire Run

A Short Fire Run (SFR) model is a specialist model to predict radiant heat flux a structure will experience in a bushfire that has not yet fully developed. It is a modified methodology to determine the Bushfire Attack Level (BAL) classification of a structure. The methodology for the calculation is a modification of AS 3959-2009 (Method 2) created by the NSW Rural Fire Service.


AS 2959-2009 provides the necessary framework for assessing the Bushfire Attack Level (BAL) of a structure. The Standard as a whole includes information regarding the improvement of a structures ability to withstand attack from a bushfire. One component of this assessment is conducting a Short Fire Run model to generate the predicted BAL.

Extra Features

Our SFR model can be run with Asset Protection Zone (APZ) optimisation and/or with the addition of a radiant heat barrier.
