Modeling the Effects of Outdoor Use of Portable Gasoline Powered Generator Exhaust on Indoor Carbon Monoxide Exposure
Steven J. Emmerich, Leon Wang
The U.S. Centers for Disease Control and Prevention (CDC) has reported that up to half of non-fatal CO poisoning incidents during the hurricane seasons in 2004 and 2005 involved generators operated outdoors but within seven feet of the home. We conducted a computer simulation study to examine the impact of gasoline-powered portable electric generators on indoor CO exposure. This paper describes the use of the CONTAM indoor air quality model coupled with two computational fluid dynamics (CFD) models to predict CO concentrations near and within a home. A variety of parameters were considered including house style, weather, generator location and distance, and generator exhaust temperature and speed. With some exceptions, the simulations showed it was helpful to point the generator exhaust away from the house and position the generator at a distance of more than 4.6 m from the house.
