An industrial hygiene and medical survey to determine airborne concentrations of total and respirable dust, nitrogen-dioxide (10102440) (NO2), nitrous-oxide (10024972) (NO), and carbon-monoxide (630080) (CO) was conducted. Employees at the Kwik Kold, Kay Laboratories (SIC-3842), Moberley, Missouri requested the survey which was conducted on April 15 and 16, and May, 1, 1981. Fifty two line workers reported concerns about respiratory and skin symptoms. Exposures for respirable particulate concentrations ranged from 0.10 to 0.45 milligrams per cubic meter (mg/m3) of air over an 8 hour time weighted average (TWA). Total particulate concentrations were particulates is 15mg/m3. With the exception of one peak NO2 measurement, all CO, NO2 and NO samples were well below NIOSH recommended exposure limits. Workers on production lines using ammonium-nitrate (6484522) were more likely than nonline production personnel to report skin or mucous membrane irritation. The authors conclude that a health hazard of systematic toxicity did not exist at the time of the survey. The authors suggest that exposure to ammonium-nitrate may cause skin and mucous membrane irritation. The recommend engineering controls, protective clothing and proper maintenance procedures to reduce exposures.
