Abstract
Environmental and breathing zone samples, taken inside supplied air respirators, were analyzed for methylene-bisphenyl-isocyanate (101688) (MDI), xylene (1330207), methyl-ethyl-ketone (78933), toluene (108883), and total aromatic naphtha (8030306) at the Rockport Construction Project of Indiana (SIC-1629) and Michigan Power Company (SIC-4911), Rockport, Indiana in November 1982. Evaluation was requested by Local 156 of the Painters Union because of concern of exposure to isocyanate painting operations. Medical interviews were conducted with 14 painters. Detectable concentrations of MDI and the other solvents were found; however, they were below the relevant standards. There was no evidence of MDI related symptoms when supplied air respirators were used. Eye irritation and shortness of breath occurred when isocyanate based paint was used prior to the use of respirators. The authors note there should be no detectable concentrations of MDI or solvents inside the respirators. They conclude that symptoms occurred when respirators were not used, thus constituting a health hazard. The source of contamination in the air supplied to the respirators cannot be determined. Recommendations include use of approved respirators according to the manufacturers instructions; smoking should not be permitted when painting.
