The University of Waterloo Chemical Inventory System (erPortal)

Chemical Inventories

The University of Waterloo has adopted erPortal's Hazardous Materials Management system to create laboratory inventories for individual labs and laboratory groups.  The purpose of this initiative is to comply with the Canadian Occupational Health and Safety Act and to reduce the overall risk associated with using, handling, and storing chemical products or agents.

To be clear, any laboratory without a current and up to date laboratory inventory is in contravention of the Occupational Health and Safety Act.
