The reconstruction of fires involving highly flammable hydrocarbon liquids
Highly flammable hydrocarbon liquids are involved in a high percentage of building fires, whether those fires are accidental or incendiary in origin. Their mere presence is often taken as proof of a particular fire cause by some investigators despite their limited knowledge of the behaviour of the …
