Laboratory closure guide

Laboratory closure guide

How to facilitate the process of laboratory closure when a principal investigator is relocating, renovating or vacating a lab space. 

When to use this guide

Use these procedures if you are closing, moving or renovating a lab that works with:

  • Chemical substances

  • Biohazardous materials (under a U of T-issued Biosafety Permit)

  • Radioactive materials (under a U of T-issued Radioisotope Permit)

These steps help ensure compliance with health, safety and environmental regulations.

Who is responsible?

Department head

  • Ensures all PIs and staff follow this guide.

  • Notifies Environmental Health & Safety (EHS) when a principal investigator relocates, renovates or vacates a lab space.

  • Is accountable for costs, fines or penalties resulting from non-compliance with this guide.

Principal investigator (PI) or designate

  • Oversees all closure tasks to ensure the lab is left in a safe and compliant condition.
  • Ensures proper disposal of hazardous materials. 
  • Provide information regarding equipment uses related to chemical, biological, radioactive and physical hazards.
  • Completes a detailed lab closure report. 
  • Ensures the lab space is safe for the next occupant or for contractors entering the space to conduct renovations.

Environmental Protection Services (EPS)

  • Acts as the lead contact for lab closure projects.
  • Assigns a Lab Closure Specialist.
  • Coordinates hazardous waste removal.
  • Conducts final lab closure walkthrough and communicates results.

Environmental Health & Safety (EHS)

  • Reviews lab hazards and conditions before relocation/renovation/closure.
  • Provides guidance and assigns safety officers (radiation, biosafety or chemical). 
  • Confirms decontamination standards are met. 

EHS director

  • Becomes involved in large and/or complicated closures.
  • Ensures that controllable risks associated with lab closure are minimized.
  • Investigates any issues of non-compliance.

Health & safety officers

  • Issues, amends or removes U of T-issued Biosafety and/or Radioisotope Permits for a lab space.
  • Advises on decontamination procedures for lab equipment and surfaces.
  • Confirms decontamination has occurred to acceptable levels.

Lab chemical safety specialist

  • Assesses hazardous chemical contamination risks (for example, perchlorates in fume hoods).
  • Recommends any needed decontamination steps.

Property manager

  • Notifies EHS when renovations are planned.

  • Coordinates with EHS for surveys and clearance.

Closure timeline and key steps

  • 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.

  • 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.

    • Seal, label and segregate biowaste

    • Seal, 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.

  • 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

  • Department head must notify EHS before any new PI moves in or renovations begin.

  • EHS will coordinate new permit approvals.
