Disposal of old or unwanted chemicals

 

Disposal of old or unwanted chemicals is organised by the Lower Campus Store, but you must:

  • Ensure chemicals brought down for disposal are safely contained within a secondary container
    • Typically, a white waste bucket is used.
    • For category 1/packing group 1 chemicals: use sealed secondary containment with full labelling and bar code to match the original container. Clean off any residue.
    • Parafilming the lids is good practise for hazardous substances. Ensure containers are not leaking (or cracked or have weeping or encrusted lids). Leaking and damaged containers must be re-packed or sealed in a secondary container before being taken to the Lower Campus Store.
  • Ensure chemicals are segregated by primary DG Transport Hazard class
    • DG Transport Hazard Class can be found in the Transport Information section of the chemical Safety Data Sheet (SDS).
    • If disposing of multiple chemicals at the same time, you cannot mix DG classes in a single secondary container (e.g. acids in one container, bases in another, flammable in a third, etc.).
  • Provide a disposal manifest to the Store
    • Please email the Store with a list of the chemicals in an Excel spreadsheet with the chemical name, quantity, Jaggaer barcode, CAS number, UN number, Packaging group and DG Transport Hazard Class.
    • UN number, Packaging group and DG Transport Hazard Class can be found in the Transport Information section of the chemical Safety Data Sheet (SDS).
    • Example manifest image is shown below along with a link to the 'Chemical Disposal Manifest TEMPLATE'.
  • Do not change the status of chemicals for disposal in Jaggaer ERM
    • This will be done by store staff immediately prior to disposal.
