Abstract
Bulk and personal air samples from the Sunnyside, Washington, area (SIC-9431) were analyzed for hazardous concentrations of respirable dust, total dust, and respirable free silica (7631869) due to volcanic ash from Mount St. Helens on June 19 to 26, 1980. The evaluation was requested by state and federal government officials on behalf of an unspecified number of outdoor agricultural workers. All personal exposures were well below the OSHA standard of 10 milligrams per cubic meter (mg/CuM) for respirable dust containing quartz, and the NIOSH criteria of 0.05mg/CuM for respirable free silica. Average exposures were low, except for total dust exposure in onion fields near Moses Lake. The higher Moses Lake exposures were attributed to the small sample size or sample contamination. Bulk and personal samples did not contain significant concentrations of toxic metals. The investigators concluded that workers in the Sunnyside area were not overexposed to respirable dust, total dust, or respirable free silica at the time of the survey. Recommendations are given for monitoring and respiratory protection in the event of future volcanic eruptions or excessively dusty conditions.
