Personal air samples were analyzed for methyl-alcohol (67561) at the University of Washington (SIC-7339), in Seattle, Washington, on April 1, 1981. An unidentified person requested the evaluation on behalf of an unspecified number of workers. The average concentration for a 25 minute period near the spirit duplicator in question was 1025 parts per million (ppm) methyl-alcohol. Concentrations for consecutive five minute periods were 1000, 1050, 1100, 950 and 1030ppm, compared with the NIOSH recommended criteria of 800ppm for any 15 minute period. At the end of the 25 minute sampling period the duplicator operator reported eye irritation. The author concludes that a health hazard from methyl-alcohol existed in the operation of the spirit duplicator at this facility. He recommends limiting operation time at the duplicator, use of a different duplicator fluid, installation of local exhaust ventilation, and regular changing of the duplicator filter.
