In compliance with UH MAPP Policies 06.02.03 and 02.04.05, Principal Investigators (PIs) must ensure that all hazardous chemicals, biological agents, radioactive materials, and wastes under their authorization/supervision are properly disposed of, transferred to another laboratory, shipped, or removed. This must be done in accordance with the UH Laboratory Checkout/Intent to Vacate Procedures.

Strict adherence to this procedure will significantly reduce the likelihood of accumulating orphaned chemicals, some of which may become dangerously unstable. Uncontrolled inventories of hazardous chemicals, biological agents, or radioactive materials will inevitably lead to storage issues, increased waste disposal costs, contamination, or potential injuries to personnel who may need to clean, reorganize, or reuse the space.

PI must notify EHS via ehs@uh.edu at least 30-days in advance of the pending move/closure by completing and submitting the Laboratory Checkout/Intent to Vacate Notification Form. Advance notice is required to allow adequate time for the scheduling of laboratory clean outs and compliance with regulatory requirements. 

1. Upon receipt of the notice, EHS will schedule a walk through with the PI or delegate and/or  the representative from the PI's department. 
2. EHS will address any safety concerns identified during the walkthrough. As a team, EHS will jointly develop a close-out plan that is customized to the laboratory and will agree upon target dates for critical process steps. 

Note: If circumstances do not allow prior notification, or the PI has already vacated the lab, the Department Head will be responsible for designating or directing the laboratory checkout procedures.
