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 Chemistry 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'.
    • When disposing of many chemicals you may find it easier to use the spreadsheet tool ('Scanning and packing form...') provided by James Webb to correlate CAS numbers with the transport information.  The spreadsheet tool is linked below and instructions are included in the first sheet.
  • Do not change the status of chemicals for disposal in Jaggaer ERM
    • This will be done by store staff immediately prior to disposal.
