The supply and exhaust systems and fume hood fan will be shut down that serve NCRC, Building 520 on Sunday, December 30th from 6:00AM - 10:00PM to install new metering devices.

All lab operations should cease during this time.

Perimeter heating will be on, but it will not be possible to regulate or adjust temperatures during this time, so please plan accordingly.

Remember that during an exhaust fan shutdown:

  • All chemical containers in the labs must be capped, or covered and properly stored.
  • All equipment requiring appropriate ventilation should not be in use.
  • It will not be possible to regulate or adjust temperatures during this time, so please plan accordingly.

Maintenance personnel will be working within the exhaust system duct work. Conducting any experiment in a shutdown fume hood, or using any duct exhaust system connected to the shutdown system is strictly prohibited during this time.

Labs: Post out the fume hoods with EHS’s “Warning Posting-Fume Hood Out of Service” poster ahead of the shutdown date. This should be removed afterwards.
