Underground shelters could be the answer to protecting people from fires because of the insulating qualities for the earth. The earth is an excellent dielectric and setting the fire bunker at least 300mm underground offers multiple times the insulation factor and fire rating of the Concrete structure. Most bush fires sustain their maximum radiant heat for less than 30 -40 minutes providing the Fire Bunkers is placed away form heavy growth. This means that the Fire Shelters cannot heat up excessively and you have plenty of air. The earth would act as a natural insulator from the heat of the fire and the bunker would not need to be too deep.

The new AS 3959 - 2009 bushfire code has just been enacted and released. This code covers the design and construction requirements for domestic dwellings being constructed in designated bushfire risk locations. With traditional design and construction it is estimated that it could cost 30% more to build in a bushfire risk location. This may cause significant financial concern for those folk that lost their homes and are now looking to rebuild their lives and homes. The Great News is that there are already several Australian Design and Building companies that have moved to address this important issue, both from a bushfire safety design aspect and as importantly in a cost effective manner that seeks to keep the costs down to or near that of conventional home construction.

Rightfully, the issue of emergency Fire Bunkers has been raised. Good old Aussie innovation has moved straight onto the job! At this time there is a portable Fire Shelter being developed that appears to cover off on both performance and design. This bunker will have up to a "2 hour" fire rating and can include up to 15 minutes oxygen supply for occupants. Looks like this product may be ideal resolve for existing homes and could be incorporated in new builds in bushfire risk areas. The inventors are also looking at bushfire shelters for the likes of horses and valued live stock.
