Air samplings and medical interviews conducted at a fiberglass tubs and showers manufacturing plant indicate that the mixture of styrene (100425) and methylene bisphenyl isocyanate is toxic at the concentrations experienced by the workers employed in this process. The effectiveness of the mechanical exhaust system is nullified by the lack of sufficient make-up air in the plant. The workers complain of respiratory and skin irritation, upset stomach, vomiting, anorexia, numb extremities, and headaches.
