The EPA has fined MRI Manufacturing and Research $30,000 for improper management of hazardous waste at the company's Tucson facility. In 2010, EPA inspections uncovered violations in the handling and storing of industrial solvents used to manufacture medical devices, such as tubing for catheters. The agency cited the company for mislabeled or unlabeled containers, failure to provide proof of employee training and inadequate record keeping at a hazardous waste small quantity generator, according to a release.
