The Hazardous Substances Calculator will help you create an inventory and work out what key requirements you need to meet, based on the hazardous substances you use, handle, manufacture and store at your workplace.
Before using the calculator for the first time you should make a list of all your hazardous substances. It may be helpful to use the Workbook for this. Once your list is complete, enter the details into the calculator to work out what key controls you need in place.
The information you include in the calculator is private and no one else has access to that information including WorkSafe. Each inventory you start is assigned a unique PIN so that you can update your inventory in future.
