Purchase, storage and disposal of chemicals

Anyone involved in the purchase, storage and disposal of chemicals — especially lab managers — should be familiar with the rules.

Purchasing

  1. All chemicals must be purchased, following approved SciTrack purchasing procedures, from SciTrack registered vendors. 
  2. All chemicals must be delivered to University premises.
  3. Newly received chemicals shall have their storage location updated in SciTrack by a Designated Laboratory Person (DLP) within one week of receipt. Note: ‘Receipt’ includes delivery by vendor and transfer from other organisations.

More information: SciTrack.

Storage

For the storage of chemicals in the laboratory, refer to the University’s Chemical Risk Management Protocol Guidelines and Safe Methods of Use (SMOU).

Refer specifically to guide Chemical Lifecycle Management and SMOU 6: Storage of chemicals in the laboratory.

Disposal

The University’s Chemical Risk Management Protocol Guidelines and Safe Methods of Use (SMOU) contain disposal instructions for certain hazardous chemical classes. Please refer to guideline "Using Chemicals" for general information, and the relevant SMOU for more detail. Chemical Safety Data Sheets also have disposal information.
