Science Department Chemical Deliveries

Chemical deliveries for the Science Departments, including those located in Carr, Clapp, Cleveland, Kendade, Reese and Shattuck are received by the Science Center Stockroom in Carr G27-North. Chemicals are entered into the inventory management system prior to being available for pickup by the faculty/staff that ordered them. Science Faculty/Staff can request OneCard access to Carr G27-North for their students that are authorized to pick up packages on their behalf by completing the OneCard Access Request Form.

Please be sure to include your name and department on all chemical orders.

Live Animal and Motor Freight Deliveries

You must notify the Science Center Stockroom in advance of all live animal deliveries and/ or motor freight deliveries (i.e. items on pallets or skids can require special handling). You must be available to receive your animals immediately upon delivery or make arrangements with a colleague to do so.

Compressed Gases and Cryogenic Liquids

Ivey Industries is our preferred supplier of compressed gasses and cryogenic liquids. Faculty/Staff should order directly from Ivey and coordinate with them to have the Driver deliver/ pick up from the location where the product is used/stored  If you will be unavailable to meet the Driver, or if you are having your cylinders delivered to/ picked up from the Carr Lab Science Center Stockroom, you must coordinate with us in advance.


Export Control

Faculty/Staff must verify with the Dean of Faculty Office that Export Control requirements are met.

Hazardous Materials Shipping

Faculty/Staff must coordinate with the Office of Environmental Safety prior to shipping chemicals, infectious materials or any other hazardous items to ensure DOT and IATA Dangerous Goods requirements are met.

Specialized Equipment and Large Items

Coordinate with the Science Center Stockroom in advance if you are shipping out specialized equipment or large items which must be picked up from the Carr Lab loading dock.

Small Parcels/Documents/Nonhazardous Items

Faculty/Staff must package items themselves and go to, or coordinate with, the Mail and Copy Center to ship out non hazardous items via USPS, UPS, FedEx or other method.

Dry Ice

Location: Carr G27-Center

Dry ice: generated on-site, is available as-needed

The Science Center Stockroom’s dry ice machine makes 1-pound bricks of dry ice. Faculty/Staff are responsible for training their own students in proper use of the machine and how to safely handle dry ice.

Science Faculty/ Staff can request OneCard access to Carr G27-Center for their students that are authorized to make dry ice by completing the OneCard Access Request Form.

Chemical Management System

The Chemical Management System, maintained by the Science Center Stockroom and EH&S, provides a searchable database for all inventoried chemicals in the science center. Please visit the Chemical Environmental Management System (CEMS) to set up your account and view your inventory.

If you find that you received a chemical directly, please contact the Science Center Stockroom to make arrangements for it to be entered into the inventory.  If you manage your own inventory, you can enter the chemical yourself by getting a barcode label from the stockroom. Enter all of the following: 

  • Enter the MHC Barcode Number 
  • Leave the Product UPC field blank 
  • Enter the manufacturer’s Product/ Catalog Number
  • Enter the Chemical Name 
    • This may auto-fill if the same product was previously entered
    • Please confirm that all info is correct, whether entering manually or if the field auto-fills
  • Enter the Owner
  • Enter the Location
    • This will auto-fill so PIs with multiple labs should make sure the location is correct
    • If the location is not in the dropdown, click the two dots to the right of the arrow to search for the location - click ‘select’ when you find it 
  • Enter the Quantity
  • Enter the Container Type
  • If the chemical has an expiration date, enter that information
  • Click Save

If the Safety Data Sheet (SDS) and hazard information do not auto-fill, the CEMS system will automatically search for it (this is not instantaneous and will happen after you logout).  EH&S will search for and upload those that the system does not complete.  

Any time a chemical changes ‘ownership’ and/ or is permanently transferred to a new lab or storage location, that information must be updated in CEMS.  

Please contact if you need assistance with your chemical inventory or if you need to be added to the MHC CEMS account.

Empty Chemical Containers - Barcodes

Lab faculty/ staff must help ensure that our chemical inventory is accurate. When a chemical is being disposed of, or the container is empty, please remove the “Mount Holyoke Chemical Inventory Barcode” and place it on the Barcode Return Log. You can keep this sheet posted near a hazardous waste satellite collection area if your lab has one or turn it into the Science Center Stockroom.

Manufacturer labels and MHC chemical inventory barcodes must not be removed or defaced unless the container is empty.  Remove the barcode and place it on the Barcode Return Log in your lab prior to reusing or disposing of the container.  

Faculty/ staff that manage their own inventory in CEMS do not need to put the barcode on the collection log, but they must be sure to mark the container as empty by logging into their CEMS account and clicking ‘MARK EMPTY’ followed by ‘SAVE’.  Following that action, please use a sharpie to cover over the barcode so others know that it has already been removed from the inventory.  Please write to with questions.

Most empty containers can be reused for hazardous waste collection.  Bottles containing acute toxins must be triple-rinsed, collecting the rinsate as hazardous waste, before the container can be disposed of.   When reusing a container, the original label must be removed, crossed out or fully covered by the hazardous waste label.   If lab personnel do not wish to reuse the container, they are responsible for disposing of it - be sure to cross out the label and write ‘empty” prior to disposing.  Unwanted glass bottles should be put in the broken glass box in the lab.  Please do not bring unwanted containers to the Science Center Stockroom.
