Compartment fires under fuel rich conditions (typical of post flashover compartment fires) have been shown to produce hazardous levels of carbon monoxide and smoke. External burning occurs when fuel rich exhaust gases spill out of the compartment, mix with air, ignite and burn. Previous research has investigated the effect of external burning on exhaust gases spilling into the open atmosphere mixing with ambient air. That research has shown significant oxidation of carbon monoxide and smoke during sustained external burning of the exhausting gases. However, the leading cause of deaths in compartment fires is carbon monoxide inhalation in neighboring rooms, remote from the fire. The present study focuses on the transport, and oxidation, of fuel rich exhaust gases spilling into enclosed spaces located adjacent to and remotely from a compartment fire.
