Environmental survey and medical evaluation of workers in a plant producing titanium dioxide pigment from ilmenite ore, involving various ore dressing techniques, including digestion, bleaching, washing, calcining, and milling. Monoisopropanolamine or MIPA and triethanolamine or TEA had been found to cause dermatitis in use prior to the inspection; titanium dioxide dust levels are found to be below standard limits. No pulmonary or noncutaneous health problems are identified. Noise levels are found to exceed standard limits. Recommendations are made for use of protective clothing if use of MIPA or TEA is reintroduced, complete implementation of a hearing conservation program, preventive maintenance program for filters, use of vacuum equipment for precluding airborne dust, and use of respirators for inert dusts and nuisance dusts.
