Gasoline and methanol exposures from automobiles within residences and attached garages
A pilot study was conducted to evaluate the characteristics of the air concentrations within a garage microenvironment. The air exchange rate between the garage and the house, the windspeed in front of the garage door, the fuel tank temperature, and the air concentrations of benzene (from gasoline) and methanol (from M100 fuel) were measured after an automobile containing US summer grade gasoline or a fabricated fuel tank containing M100 fuel entered the garage and its door was closed. The air concentrations in the garage were greatly elevated after the car or M100 fuel tank entered the garage compared to the ambient levels which were present prior to the car's entry. A steady state concentration was often reached within 90 minutes of the automobile or fuel tank entering the garage and the air concentration remained level until the fuel tank temperature returned to ambient levels, several hours later.
