Abstract
On December 14, 17, and 18, 2001, a field survey was conducted at a construction site where a built up asphalt roof was being installed on a new wing being added to Carroll Bell Elementary School in San Antonio, Texas. The survey was conducted to evaluate the effectiveness of using an afterburner system with a safety loading door on an asphalt kettle to reduce worker exposure to asphalt fumes. Personal breathing zone and. area air samples were collected and analyzed for total particulate (TP), benzene soluble fraction (BSF) of the TP, and total polycyclic aromatic compounds (PAC). These three analyses were chosen to represent indices of exposure to asphalt fumes. Air samples were collected with the afterburner on and the kettle lid closed. The afterburner system could not be turned off at this site due to the close proximity of the construction site to the rest of the school; therefore no samples were collected with the afterburner system off. Air samples were collected on the kettle operator and two roof level workers; area air samples were collected around the four corners of the kettle. Because only one control condition, afterburner on and kettle lid closed, was used, it was not possible to make comparisons to show the effectiveness of using an afterburner system with a safety loading door to reduce worker exposure to asphalt fumes during the installation of a built up asphalt roof. The results are simply reported as collected and will be added to results from other survey sites.
