Environmental samples were analyzed for sulfur (7704349), hydrogen- sulfide (7783064), sulfur-dioxide (7446095), and particulates for the Wisconsin Department of Transportation (SIC-1611) on State Highway 31 west of Racine, Wisconsin in June 1982. The survey was requested by a representative of the Wisconsin Operating Engineers on behalf of employees working on paving projects because of possible hazards associated with using sulfur extended asphalt. Workers reported nosebleeds, chapped and split lips, severe sunburn, and extreme nausea and vomiting. Breathing zone air samples were analyzed for sulfur, hydrogen-sulfide, sulfur-dioxide, and particulates. Long and short term samples revealed no detectable concentrations of sulfur-dioxide. Hydrogen-sulfide was detectable in only trace amounts. Respirable particulates were composed entirely of sulfur. One personal air sample was above the OSHA standard for total particulates of 5.0 milligrams per cubic meter (mg/m3). This sample had a particulate concentration of 5.1mg/m3. Effects of long term exposure on workers could not be determined. The author concludes th t particulate sulfur emissions from sulfur extended asphalt causes eye and upper respiratory mucous membrane irritation. It is recommended that asphalt temperatures be maintained below 300 degrees-F to reduce gaseous emission does not occur. Eye protection and respirators should be made available.
