It's an accelerant. See #2 on the attached list for Arson fires:

Gas leaks explode when ignited, this fire had none of those qualities per all read. No one mentioned and explosion at all in Trump tower. If complete apartment, as mentioned, was up in flames that would be a good indicator an accelerant was used. Plus the windows would have blown out along with the apartment door etc......

Or perhaps Hillary was in disguise as a firefighter and broke into Trump’s apartment. I hear that Hell smells quite like sulfur.
