Shut the Sash

Save energy. Be Safe.

What is a sash?

A sash is a sliding glass door that is attached to a fume hood, that opens and closes. Fume hoods are attached to a building-wide ventilation system that sucks away chemical fumes.

Why shut the sash?

When a sash is closed, a valve attached to the hood decreases the flow of air to the hood. When enough sashes are shut, the fan assigned to those hoods also slows down into a more energy-efficient mode. A single fume hood running 24 hours uses as much energy as a single-family home. Improving energy efficiency through fume hood use is one of the many UCR can cut down on usage and cost. Read more.

Energy saving habits
  • Close the sash after storing and removing chemicals.
  • Make sure your hood is closed before leaving.
  • Inform your fellow collegues about "shutting the sash"

    Login to the Chemical Inventory system to view, or update, the database of chemicals we have on file for you. Owners must declare their inventory status even if there are zero chemicals in stock when the inventory is conducted. You must also update the online chemical inventory database when you: 1) Move to a new location, 2) Acquire a new hazardous chemical, or 3) Change your inventory volumes greater than 10%.
  4. Complete the Chemical Inventory Confirmation

    Owners  must complete the Chemical Inventory Confirmation form. The form, which notifies EH&S of inventory changes, should be completed anytime a chemical inventory is updated online (anually, at minumum).
    NOTE: The form should also be completed if, at anytime, a lab owner exceeds thresholds for Department of Homeland Security
    Chemicals of Interest (6 CFR 27, Appendix A).
