“Original research is being conducted on the combustibility and inflammability of successive plant regrowth as these fires accumulate.”

“In particular, the formation of branched alkanes increases the octane number and combustibility of the resulting hydrocarbon.”

“An independent forensic specialist determined that the foam's combustibility was equivalent to 13 gallons of gasoline.”

“Several involve body-shaped depressions in the earth that are filled with fabric or other combustibles, set afire and left as an imprint of ash.”
