Environmental survey of hazards from isocyanates, paint sprays and solvents in a plastics molding plant reveals concentrations of toluene-2,4-diisocyanate (584849) (TDI), toluene (108883), xylene (1330207), and acetone (67641) vapors are within established safe limits. An excess of methyl-ethyl-ketone (78933) (MEK) is found only in the arm rest washing area. Noise levels in excess of established standard are found near rotational casting machines. Recommendations include use of respirators when cleaning TDI spills, removing workers with respiratory symptoms from exposure to TDI, yearly chest x-rays and forced vital capacity testing for workers exposed to TDI, local exhaust ventilation, respirators, and protective gloves for workers handling MEK, substitution of a less irritating compound for petroleum naphtha (8030317), and ear protectors and audiometric tests for workers on casting machines.
