Modeling A Real Backdraft Incident Fire
Author(s)
A. Tinaburri & M. Mazzaro
Abstract
This paper reports the fire conditions that occurred in a townhouse and the
results of software simulations that were performed to provide insight on the
peculiar thermal conditions that developed. Fire rescue was called by the
occupants of the house when they became aware that smoky conditions were
developing on the second floor. Two of the firefighters entered the bedroom
where the smoke was originating from and a short time after a flame front
invested them while propagating them backward into the stairwell. The post fire
investigation determined that the fire started as a consequence of the smoldering
combustion of material contained in a wardrobe located adjacent to one of the
room walls. A simulation scenario was developed based on the information
obtained on the actual building geometry, material thermal properties and the fire
behaviour. The calculations that best represented the actual fire conditions
indicate that the partial opening of the window and bedroom door provided
outside air (oxygen) to a pre-heated, under ventilated fire compartment.
Keywords: smouldering combustion, backdraft, fire models, fire investigation.
1 Introduction
Part of the mission of the department of the firefighters, public rescue and civil
defence is to conduct basic and applied fire research, including fire
investigations, for the purposes of understanding fundamental fire behaviour and
to reduce losses from fire. On February 3, 2003, a fire in a townhouse near Lucca
