Fire investigators regularly evaluate available fuels and potential ignition sources to determine the cause of a fire. This work examined the propensity of lit cigarettes to ignite gasoline vapors, expanding on previous work to include a large number of trials and a wide range of test conditions. Experiments were conducted exposing lit cigarettes, both at idle and under draw, to gasoline vapors in various configurations including pools/pans of gasoline, gasoline on textile substrates (clothing), and sprays of gasoline. Five major brands of commercially-manufactured tobacco cigarettes were tested. The experiments conducted for this study consisted of 70 distinct tests involving a total of 723 cigarettes and over 4,500 instances of exposure of a lit cigarette to ignitable concentrations of gasoline vapor in air. There were no instances of the ignition of gasoline vapors from the exposure of those vapors to a lit tobacco cigarette during any of the experiments.

Abstract
A recent murder enquiry prompted experimentation to confirm and visually demonstrate that lit cigarettes are not a viable source of ignition of petrol vapour. In addition, tests comprising the attempted ignition of petrol vapour using hot and smouldering cannabis resin were also undertaken. A series of experiments was also designed to recreate circumstances specific to the crime under investigation by undertaking cigarette/joint ignition tests involving a mannequin clothed in a cotton garment onto which petrol was applied. The ultimate aim of the experiments was to produce a visual aid for use during court proceedings. Thirty nine (39) ignition attempts that involved exposing lit commercial cigarettes, hand-rolled cigarettes and cannabis resin joints to petrol vapour were undertaken; ignition was not achieved in any of the scenarios. In addition, a single attempt to ignite petrol vapour emanating from a pool of liquid fuel was effected with a smouldering piece of cannabis resin; no ignition occurred. In all cases the petrol was clearly present within the limits of flammability since ignition was subsequently effected using a naked flame.

"On the face of it it's a pretty simple problem," said Richard Tontarski, an expert in forensic fire at the Bureau of Alcohol, Tobacco and Firearms research laboratory in Beltsville, Maryland. Cigarettes burn at around 700C (1,292F) and the ignition temperature of petrol is 246C. "But it just isn't that simple," he said

Hopefully, his insurance company is smarter than people who repeat unverified claims

One injured but well enough to refuse advice to be transported. Thank goodness.

The gas cans and fictional reddit cigarette had nothing to do with the fire...
