Thanks for your question, Joseph.
Since it's important to destroy these confidential documents, perhaps taking them to a commercial shredding service in your area would be the best solution. That would preclude worries about contaminating your institution's equipment. It would be interesting to hear responses from others who have encountered this problem.
