Laboratory closure guide
What to do when relocating, renovating or vacating a lab space at the University of Toronto.
Overview
This guide supports principal investigators (PIs), departments and research teams in closing, moving or renovating labs that work with:
- Chemical substances
- Biohazardous materials under a U of T-issued Biosafety Permit
- Radioactive materials under a U of T-issued Radioisotope Permit
Following these procedures ensures compliance with health, safety and environmental regulations.
When to use this guide
Use this guide if you are:
- Closing a laboratory
- Moving to a new lab space
- Preparing for renovations
- Vacating a lab due to retirement, relocation or program changes
Getting started
Before work begins, ensure you:
1. Submit the exit / renovation / decommissioning form
This form is required to begin all lab closure or renovation activities and ensures that the Environmental Protection Services team can properly coordinate the process. Email the completed and signed form to eps.hazdisposal@utoronto.ca.
2. Contact Environmental Health & Safety
EHS will review existing hazards, permits and conditions before any removal or decommissioning takes place.
3. Assign a lead (PI or designate)
A PI or their designate oversees the closure process and ensures all disposal, decontamination and reporting steps are completed.
Closure process: Timeline and steps
EPS and EHS work together to ensure proper closure, waste removal, hazard decommissioning and walkthroughs. The typical sequence is:
At least four weeks before closure
Department head notifies EPS manager: gord.petre@utoronto.ca.
EPS assigns a lab closure specialist.
Initial lab survey is completed with PI/designate, EPS and EHS.
If multiple labs or PIs are involved, contact the EHS Director.
Property manager is included if renovations are planned.
Two weeks before closure
PI/designate circulates a hazards list to:
EPS lab closure specialist
Department head
Property manager
EPS coordinates with appropriate EHS group:
Biosafety for biological materials, equipment and permits
Radiation Protection Services for radioactive materials, equipment and permits
Lab chemical safety specialist for hazardous chemical use and permits
PI/designate fills out and submits required forms and updates their HECHMET inventory:
Bio-permitted labs: Complete the Exit / Renovation / Decommissioning Form (PDF)
Submit form to eps.hazdisposal@utoronto.ca or the EPS Manager (gord.petre@utoronto.ca) and inform Health and Safety Officer of form submission
- Contact the U of T HECHMET administrator for additional information and assistance
Chemical and non-permitted labs: Complete the Exit/Renovation/Decommissioning Form (PDF)
- Submit form to eps.hazdisposal@utoronto.ca or the EPS Manager (gord.petre@utoronto.ca)
- Contact the U of T HECHMET administrator for additional information and assistance
Radioisotope labs: Submit written notice to your Health and Safety Officer and follow radioisotope decommissioning procedures
Just before closure
Lab staff must label and prepare hazardous waste for disposal:
Affix chemical waste labels to all chemical containers.
Return gas cylinders to suppliers or report non-returnable cylinders to EPS.
Package, label and segregate biowaste
Package, label and segregate radioactive waste and unused radioactive supplies.
PI/designate schedules decontaminated equipment and non-hazardous material removals with the Campus Moving team.
PI/designate attaches a Safe to Remove tag (PDF) to any decontaminated lab equipment ready for disposal or relocation.
Closure day (lab is vacant)
PI/designate and EPS lab closure specialist inspect lab space.
Confirm all hazards are properly removed.
PI/designate notifies:
Department head and property manager that lab is ready for new occupant or renovations
Caretaking services for any required cleaning
PI/designate sends final closure report to:
Department head
Property manager
EPS lab closure specialist
- PI/designate finalizes their HECHMET inventory to show that no hazardous materials are located in the lab spaces they are vacating.
After closure (new occupant)
Department head must notify EHS before any new PI moves in or renovations begin.
EHS will coordinate new permit approvals.
