    Chemical waste is considered Hazardous Waste if it is either listed as such, or if it exhibits one or more of the following hazardous characteristics: Ignitable, Corrosive, Reactive or Toxic.

    Ignitable Waste
    Any waste whose flash point is less than 140 °F.
    Corrosive Waste
    Any waste with a pH lower than 2.0 or greater than 12.5.

    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.
