Breathing zone and general area samples for Counter-15-G (13071799) insecticide, respirable particulates, total particulates, and respirable free silica were collected, and 21 employees were interviewed at the Hopkins Agricultural Chemical Company (SIC-287) in Atlanta, Illinois on January 9 to 11, 1979. An authorized employee representative requested the evaluation to assess toxic exposures of 10 to 20 employees. Gas chromatographic sample analysis revealed that all contaminants were below OSHA criteria for crystalline-silica, and respirable and total particulates (10 milligrams per cubic meter divided by the percentage of quartz plus 2, 5 milligrams per cubic meter, and 15 milligrams per cubic meter, respectively). No standard exists for exposure to the insecticide, but measured concentrations were low (0.002 to 0.011 milligrams per cubic meter). The authors conclude that no health hazard to workers existed at the time of the evaluation and recommend enclosure of local exhaust ventilation hoods, use of personal protective equipment to prevent oral and eye exposures, and continuation of a program of cholinesterase monitoring.
