Apr 14-31 Mathews – closed to all occupants (switchover to new exhaust system)
The building will be operating in a condition of reduced capacity of fresh air. There will be NO exhaust from fume hoods or the liquid nitrogen fill room (1245). Air circulation in the building will be accomplished by opening windows in laboratories by a small amount to allow the tempered supply air to escape. (Windows will not be opened in office areas.)
Impacts to the entire department
- NMR facility will be closed
- Research stockroom will be closed
Liquid nitrogen facility will have limited accessibility
Large, closed-container liquid nitrogen Dewars may be filled in Rm. 1245 DURING BUSINESS HOURS (8 AM – 4 PM)
Open-container liquid nitrogen Dewars MAY NOT BE FILLED in Rm. 1245. If you typically draw liquid nitrogen in open Dewars, you will need to fill from a transport Dewar located at the loading dock, or, depending on your expected usage during the period of Mathews shutdown, you may need to order your own Dewar of liquid nitrogen from AirGas.
Solvent storage room, gas cylinder room, loading dock will have limited accessibility
- only during business hours and only by prior arrangement with Adam
- incoming packages delivered to office of group PI
A crane will be located near the loading dock.

This information supersedes any approvals regarding building access that you may request or receive via the Marauder map.
Occupants of Mathews wing: The following steps are being asked to protect construction workers, protect staff members who may need to check on lab status during the construction period, and protect your equipment and materials left behind.
- Please ensure that there are no active experiments.
- All chemical containers must be closed and capped.
- Remove all items from the window sills and the window walls in laboratories. Maintenance personnel will need clear access to all windows in Mathews laboratories. It is conceivable that a driving rain could cause water to enter the lab. Relocate items that might be impacted.
- Affected areas need to be shut down and stabilized. Assume you cannot enter the area during the entire 16-day shutdown.
- Clear and clean all bench tops. Put away, into cabinets and drawers, all glassware and other loose breakable or potentially hazardous objects.
- Remove all clutter from floors, including empty bottles.
- Remove all items from drying racks.
- All chemicals must be put away and secured in an appropriate location. No bottles of chemicals may remain on open shelves in the lab. This means chemicals must be stored in:
- Appropriately rated chemical storage cabinets
- Inside fume hoods
- In cabinets below fume hoods
- Moved into another laboratory location outside the project area
- Non‐hazardous chemicals (not flammable, corrosive, or volatile) can be temporarily moved into any sturdy wooden cabinet.
- Carboys need to be capped and moved into secure location inside a cabinet or fume hood.
- Fume hood sashes need to be closed
- Biological labs, use an appropriate disinfectant.
- Biosafety cabinets (BSCs): protect HEPA filter with plastic and plywood (or similar hard material).
- Labs with radioactive materials should work with Radiation Safety to secure their materials.
- Gas cylinders may remain with regulators in place. If possible, close cylinder valve and depressurize regulator.
- Glove boxes may remain in normal operating condition.
- Electrical / mechanical equipment (lasers, electronic devices, vacuum pumps, machines):
- Refrigerators and freezers may remain in operation.
- Simple equipment (vacuum pumps beneath fume hoods, ovens, etc.) should be deenergized.
- Large equipment or vacuum systems may remain in operation only if it is feasible for them to be unattended for 16 days. If it is not possible to operate, unattended, they should be deenergized.
- Any high‐value materials should be secured.
Thank you for your cooperation! Facilities Committee
