摘要

This project studies the vulnerability of rotting marine structures (such as wharves and docks)rnto ignition by discarded cigarettes. The phenomenon of rotting wood was examined in detail, andrnrelated to the manner in which creosoted piles rot. Several informal tests demonstrated the ignitionrnmechanism of rotting wood by an ignited cigarette. A series of tests determine the moisture contentrn(MC) below which rotten Douglas Fir (also called Douglas tree, and Oregon pine; genus Pseudotsugarnmenziesii) will ignite and smoulder. Another series of tests determined the rate at which creosotedrnDouglas Fir piles used for docks and wharves will dry to the point at which they are ignitable byrncigarettes. Historical records are consulted to determine the amount of rainfall before the fire. Byrncomparison of the two studies, the moisture content of creosoted piles in a marine structure wasrnestimated and a timeline towards ignitability was determined. A third set of four concurrent tests usesrncigarettes to ignite rotten wood in exemplar test piles which smouldered and then transitioned intornflaming combustion. The process was witnessed and photographed in detail. The results informedrnthe likelihood of ignition by cigarette of a particular wharf structure in 2003 and other structures ofrnsimilar construction. The likelihood of fires of similar origin was considered, and means to preventrnthem is discussed.
