Collection and Storage of Hazardous Chemical Waste Procedures

  1. Waste Oil
    Waste oil can be found in many types of compressors, pumps, transmissions, etc.
    • Collect waste oil in a clean drum. If oil is collected in a used container, rinse the container and deface any labels. Since oil is recycled, ensure it is not cross contaminated with other materials.
    • Containers must be closed. A bung must be in place on all drums when oil is not being added.
    • Label the container when oil is first added. Label as "waste oil". Include the start date (date oil first added to the container) and the generator.
    • Once the container is full, no longer needed, or within nine (9) months from the start date, prepare for shipment to an authorized waste facility.
  2. Oil Filters
    • Drain oil filters and collect the waste oil as described above.
    • Once completely drained, place the oil filters in a container and label as "waste oil filters", include the date and the owner.
    • Bring the waste filters to the LSCS Facilities Department waste storage site for shipment to an authorized waste facility.

Shipping on a Hazardous Waste Manifest Directly From Your Location
All of the hazardous waste manifests for the campus are managed centrally by the LSCS Facilities Department for hazardous waste regulatory reporting. It is important that all original copies of hazardous waste manifests are sent to the campus Facilities Manager immediately after the shipment is sent. The mailing address must also include the campus Facilities Department so that the return copy that comes back from the receiving facility will be appropriately filed.

Contact the campus Facilities Department before shipping hazardous waste yourself.
