Workers directly involved in spray painting large commercial aircraft (SIC-5084) are found to be exposed to toxic concentrations of organic solvents and isocyanate compounds during such operations. Environmental measurements indicate levels of specific organic solvents such as methyl-ethyl-ketone (78933), toluene (108883) and cellosolve-acetate, exceed the threshold limit values. Significant concentrations of hexamethylene-diisocyanate and the biuret compounds of hexamethylene-diisocyanate were measured. A significant increase in symptoms of eye irritation, nasal- irritation, throat irritation and chest discomfort is found in workers engaged in spray painting when compared to non-exposed workers. Recommendations are included which are designed to reduce exposure to these agents to a minimum.
