Laboratory Decommissioning

When a principal investigator is vacating a University laboratory due to retirement or a move or lab is undergoing renovations either partial or complete, the laboratory and associated research areas such as storage rooms, must be properly closed. Permits need to be decommissioned and the lab space closed so new tenants or contractor are safe to enter the space. Advance planning enables the University to effectively close research space and eliminates the need for costly emergency decommissioning of facilities.

Permits for Biosafety, Radiation or Chemical need to be decommissioned before the laboratory itself can be closed. The University has established a Guideline for Laboratory Closures.
