Chemical Waste Disposal

  • Any hazardous waste that may need disposal from another part of the campus is moved to the chemical storage room for disposition. The movement of this waste is coordinated between the Office of Public Safety and the coordinator of the chemical storage room.

    Indiana University of Pennsylvania has entered into a hazardous waste removal contract along with other SSHE universities. Waste is removed from the campus on a quarterly basis.

    The Kopchick College of Natural Sciences and Mathematics has developed an extensive Chemical Hygiene Plan. Because of its length, it has not been incorporated into this document. The plan is kept with this document for reference when needed. The table of contents page has been incorporated into the appendices.

    Defining Hazardous Waste

    The Environmental Protection Agency (EPA) has defined a hazardous waste as any material that no longer has a use and is either specifically listed in the regulations or meets defined hazard characteristics.

    • Liquids that have a flash point less than 140°F (60°C)
    • Flammable solids
    • Flammable compressed gases
    • Oxidizers


    • Aqueous solutions with pH less than 2 and greater than 12.5
    • Corrodes steel


    • Water reactive substances
    • Unstable or explosive chemicals
    • Cyanide or sulfide containing chemicals that generate toxic gases when exposed to corrosive substances


    • Materials that have certain heavy metals or organic constituents above regulated limits (EPA D List) (see EPA Waste Finder)
    • Materials that meet or exceed TCLP laboratory testing (see Materials Safety Data Sheet)
    • Contact Environmental Health and Safety for additional toxicity information
