Potassium iodide is permitted in WA schools. However, it is important to be aware that iodine and all iodide salts have been identified as precursor chemicals that could be used in the illicit manufacture of drugs.1 This has implications for both the supply and storage.
Supply of chemicals and End User Declarations: Iodine and iodide salts are listed as Category II illicit drug precursor chemicals, which means that they require an End User Declaration (EUD) prior to their supply, when sold to non-account customers.1 Different states and territories may currently have different conditions concerning requirements for EUDs, but this is in the process of being harmonized across Australia.2
In general, the following information is required on an EUD:
- the name and address of the purchaser,
- proof of identity of the purchaser such as passport number or driver’s licence number,
- name and quantity of the chemical to be supplied plus its intended use.
Some companies require an EUD for every order request.
The person responsible for the chemical’s end use should complete and sign the End User Declaration. This should be a senior member of staff such as the Head of the Science Department.
Note: It is not the responsibility of the science laboratory technician to complete this form.
Storage: Iodine and iodide salts should be stored locked up3 to prevent unauthorised access. It is best practice to store minimal quantities of all chemicals to enable easier management of chemical segregation and chemical stocktaking.
Regular checks of stock levels are recommended to fully account for all chemicals, including their location.
