exposure

Exposure refers to parts of the same structure or other structures or property not directly involved in the fire but at risk of being burnt or damaged if the fire is not controlled. In the bushfire context:
1. Property that may be endangered by a fire burning in another structure or by a bushfire. In general, property within 12 metres of a fire may be considered to involve an exposure hazard, although in very large fires the danger may exist at much greater distances.
2. Direction in which a slope faces, usually with respect to cardinal directions (N, S, E, W).
3. The general surroundings of a site, with special reference to its openness to winds and sunshine.
