Abstract
Volcanic ash exposure was monitored for camp counselors and camp participants of the Gales Creek Diabetic Camp, (SIC-1499) in Glenwood, Oregon, from June 30 through July 25, 1980. A representative of the Health Division of the Oregon Department of Human Resources requested the evaluation subsequent to the eruption of Mount Saint Helens. Respirable dust concentrations ranged from undetectable to 1.25 milligrams per cubic meter (mg/Cum), compared with the American Conference of Governmental Industrial Hygienists (ACGIH) threshold limit value of 5mg/Cum. Total dust concentrations ranged from undetectable to 4.87mg/Cum, less than the ACGIH criteria of 10mg/Cum. Estimated respirable concentrations ranged from undetectable to 0.04mg/Cum, compared with the NIOSH recommended standard of 0.05mg/Cum. Bulk sample analysis of volcanic ash indicated its crystalline silica content to be 2.9 percent by weight of the less than 10 microgram fraction. The author concludes that there were no excessive exposures to volcanic ash at this facility. He recommends that in the event of increased volcanic ash fallout outside activities should be curtailed, and respiratory protective equipment be used outside when environmental conditions warrant their use.
