Each laboratory is responsible for staying informed of, and complying with Hazardous Waste regulations, and for following the University procedures regarding waste collection, segregation, and labeling. The chemical safety officer will provide all materials necessary for the proper management of waste, from personal protective equipment (PPE) to labels and waste containers. All items are available at the chemical stockroom (Room S-310) upon request. If you need postings or forms, please download them from this site.
