                                                 5


Elevation of receiver - Douglas & Tan, 2005
Flame angle - Douglas & Tan, 2005
Radiant heat flux - Drysdale, 1999, Sullivan et al., 2003, Douglas & Tan, 2005


   13. Therefore, the minimal distance that achieves a Radiant heat flux of 29kW/m2 is 12.4
       metres and this spatially located on Figure 1 and the light blue line.
Conclusion
Based on the above analysis we can conclude that;
   1. The exempted clearing distance for the existing development and the proposed
      development is a clearing with of 24.0 metres.
   2. However, the only clearing that is necessary is that which achieves a radiant heat flux of
      29kW/m2 is 12.4 metres, the only clearing that is required of any area of category is that
      which is within 12.4 metres of the closest edge of the existing and proposed infrastructure.
   3. As the 12.4 metres necessary clearing distance for a necessary firebreak is less than the
      1.5 time the height of the tallest adjacent trees, this clearing is considered to be exempted
      clearing.
