An environmental medical study performed of the electroplating processes of the Industrial Platers, Inc. (SIC-3356), Columbus, Ohio, revealed that chromic-acid (13907454) exposure is a hazard for the employees within the hard chrome area. Four men had perforated nasal septa and 2 others to have some degree of septal ulceration. Cutaneous scars resulting from past chrome ulceration were noted in 9 of the 11 employees examined. While the majority of the signs and symptoms of chromate exposure elicited during this study dated back at least several years, there was evidence that adverse effects are continuing to occur within this plant. As evidence of this, are the five individuals in whom injected nasal mucosa were noted and the 2 men with active septal ulceration. While several workmen who are long-term employees described numerous beneficial changes in ventilation, it is apparent that some adverse effects from chromic- acid are still occurring. Workroom airborne concentrations of chromic-acid as measured during this evaluation were well below any existing or recommended standards. The observations of work practices, including the use of personal protective equipment, the presence of characteristic orange chromate stains on workers' skin and the results of spot tests in the work area suggest that much of the nasal and cutaneous pathology that have occurred and continue to occur within this plant probably result from direct contact with the hexavalent chromate ion rather than through airborne exposure.
