• Description:
  Industrial hygiene characterization of exposures in an automotive wood model shop (SIC-3999) was examined. Respirable dust samples were collected. High volume air samples were weighed to determine total dust loading and then analyzed by one of two methods: solvent extraction and Ames Salmonella/microsome assay system or solvent extraction and analysis by gas chromatography/mass spectrophotometry. Volatile amines and organic solvents were collected and analyzed with a thermal energy analyzer. Formaldehyde (50000) samples were analyzed by ion chromatography. Personal total dust samples ranged from 0.05 to 29.4 milligrams per cubic meter (mg/m3). Respirable dust concentrations ranged from 0.01 to concentrations of dust. Sweepers were the second highest dust exposure group. The mass median aerodynamic diameter of impactor samples ranged from 5.2 to 10 microns the diameter of respirable dust was 1.7 microns. None of the samples were above what are considered the OSHA permissible exposure limits (PEL). The highest area samples for total dust were measured near the routers and shapers. The concentrations of organic solvents were below PEL. No N-nitrosamines were detected. No formaldehyde was detected at concentrations above 0.01 part per million. The mutagenicity tests were inconclusive. The authors conclude that although no significant air contamination is present, safety measures should be used to keep all exposures at the lowest possible concentrations.
