  • Chemical waste responsibilities Follow University procedures for labeling, storing and disposing of hazardous waste.

    Minimize the amount of waste generated.

    Recycle unused chemicals via the University redistribution program.

    Prepare ahead of time for spills or other mishaps.*

  • *Waste Properties

  • What is a hazardous waste? A hazardous waste can be defined by one or more of the following characteristics:IgnitableCorrosive*ReactiveToxicListed Waste


  • Chemical waste is considered hazardous if:

    The flashpoint is < 140 F (60 C) An aqueous solution contains > 24% alcohol It is an oxidizer It is a flammable compressed gas It is a liquid capable of fire through friction, absorption of moisture or spontaneous chemical change.*

  • CorrosivityChemical waste is considered corrosive if:

    It is an aqueous solution with a pH < 2 or >12.5

    It corrodes steel at 6.35 mm/year at 55 C*

  • ReactivityA chemical waste is considered highly reactive if:

    It is capable of creating toxic gases when mixed with water

    It forms explosive mixtures with water

    It is cyanide or sulfide bearing*

  • ReactivityIt reacts violently with water

    It is normally unstable

    It is capable of detonation

    It is a DOT classified explosive*

  • To icityA chemical waste is considered highly toxic if:

    It contains arsenic, barium, cadmium, chromium (VI), lead, mercury, selenium or silver*

  • ToxicityIt contains one or more of these 32 organic compounds: *BenzeneCarbon tetrachloride ChlordaneChlorobenzeneChloroformm-cresol p-cresolo-cresolp-dichlorobenzene2-dichloroethylene 1,1-dichloroethylene 2,4-dinitrotoluene Endrin Heptachlor Hexachlorobenzene Hexachloro-1,3-butadieneHexachloroethane LindaneMEK methoxychlor nitrobenzene pentachlorophenol pyridine tetrachloroethylene toxaphene trichloroethylene 2,4,5-tetrachlorophenol 2,4,6-trichlorophenol vinyl chloride 2,4,-D 2,4,5-TP silvex

  • Listed Waste LabelsWaste label categories:

    F waste hazardous waste from non-specific sources (solvent can waste)

    K waste hazardous waste from specific sources (distillation bottoms)

    P and U waste discarded commercial chemical products, off spec products, container residues, spill residues (generally discarded chemicals)*

  • *Waste Collection

  • Collection of hazardous chemical wasteUse containers that are compatible with the chemical waste.

    For large quantities, DEC can provide 30 or 50 gallon drums or 5 gallon plastic containers.

    Keep containers capped and store them in a safe location in the laboratory.

    Do not store incompatible chemicals together in the laboratory.*

  • Hazardous Chemical Waste CollectionLabel containers. An original container and label can be used if the label is legible. Blank labels can be obtained by contacting NYSDEC at 518-402-8651.

    Only collect wastes that are compatible in the same container A hazardous waste mixed with a non-hazardous waste becomes hazardous waste.*

  • Hazardous Chemical Waste CollectionSpent solvent waste can not contain metals, cyanides and sulfides. Spent solvent waste must have a pH >5 and
  • Disposing of the chemical wasteChemical waste will be picked up by the NYS Department of Environmental Conservation through the university chemical waste office.

    A pick-up can be arranged via telephone, fax, mail or online.


  • Required informationRegardless of how the request is submitted, the following information must be provided: Name and DateTelephone numberDepartmentBuilding and room numberChemical compound name and approximate quantity*
