Chemical inventory system

Chemical inventories must be input into the Safety Office supplied inventory module by all research facilities or upon request of the Safety Office. These inventories must be maintained and verified on a minimum of a yearly basis. All labs are to have their inventory uploaded and certified by the end of Winter 2023!

Completion of these inventories aids in:

  • Inventory control
  • SDS compliance through linking most inventory items to SDS database
  • Regulatory reporting on chemical quantities (such as the Chemical Weapons Implementation Act).
  • Hazard recognition (e.g., peroxide formers can be easily identified and status tracked)

For inventory items that do not have SDSs automatically linked, the PI must upload an SDS to the inventory module.

Laboratories may choose to use another software (such as Quartzy or Excel), or process to store their inventory in, but they will still be required to complete the annual inventory reconciliation process on Risk and Safety Solutions. As a result, they will want to ensure they store all mandatory bulk upload fields (yellow) from the Inventory Template for Importing a Laboratory Inventory in their other software system for easy annual uploading or tag their inventory using RFID tags. If an alternative is used, ensure that SDSs are readily available at all times in the laboratory. It is recommended that laboratories download their customized bulk upload form from their laboratory inventory page for use for uploading. Contact to discuss your options if you want to use two systems.

    Annual reconciliation

    Getting started

    For those starting your laboratory inventory review, here are a couple recommendations to help with the process:

    • Discard old chemicals that will never be used rather than using resources to relabel and add to your inventory. Contact if you expect to be discarding large quantities of chemicals. More information is available on the Hazardous Waste page.
    • Inspect bottles for damage during the inventory process.

    Developing an inventory

    Follow the steps below to develop an inventory. Refer to the drop-downs in each step for instructions. 

    Step 1 of Starting Your Inventory: Complete a Part 1 Meeting to add your Group

    To get your group added to the Chemical Inventory system, book a Part 1 meeting for an introduction to the system and have your customized group created.

    Step 2 of Starting Your Inventory: Update your Users and Locations (Completed by PI or Delegate)

    Step 3 of Starting Your Inventory: Create Your Inventory and Add Sublocations (Completed by PI or Delegate)

    Step 4 of Upload and Maintain Your Inventory: Add and Delete Chemicals (Completed by any member of the Group)

    Optional Add-On: Using RFID
