Time Scales of Gaseous Smoke Contamination Indoors from Real and Simulated Wildland-Urban Interface Fires.

ABSTRACT: Fires occurring at the wildland-urban interface (WUI) can produce smoke, that contains unique chemicals from the combustion of urban structures, which can then contaminate nearby buildings and affect indoor air quality. Assessing property loss and possible occupant exposure to persistent contamination from WUI smoke is challenging, in part because of a lack of measurements detailing chemical contamination in real indoor environments after WUI events. Here, we mimic contamination from a WUI fire by repeatedly exposing a test house to smoke from combustion of residential building surrogates and measure the persistence of volatile nonmethane organic gas (NMOG) contamination. Over the 1.5 month experimental period, we observed an increase in emission rates of 31 NMOGs, indicating the formation
