Laboratories which utilize biological materials must notify the Biosafety program prior to terminating work to ensure that the laboratory has been decontaminated and that the biological material has been secured or properly disposed. If the Principal Investigator intends to cease work, he or she must notify Biosafety at least 60 days prior to the set departure/closing date. This will allow Biosafety to consult with the Principal Investigator and perform a walkthrough of the lab to provide recommendations on the most expeditious way to prepare for the move and the final termination of the biohazardous work in the lab (Figure 1). A final Lab Deactivation Inspection will be scheduled accordingly.
