- Abstract
Abstract results are given for the fire ignition tendency of a selection of naturally occurring fuels exposed to irradiation and to incadescent droplets of aluminium, brass, copper and steel. It is shown that the conditions which create a high fire risk are those that arise with steel and aluminium particles. Copper is a much reduced hazard, but still capable of ignition when present at droplet sizes of 2 to 3 mm. Contact sparking creates such small particle sizes that fire ignition after a fall of several metres, is most unlikely. A comparison is made with the results of the standard ISO test of ignitability with those of ignition due to small, incandescent droplets. The results differ substantially, due to very considerable fanning of incipient smouldering points for the ISO test.
