When a laboratory is being vacated, it is important to follow proper decommissioning procedures to ensure the laboratory is in a safe condition for the next occupant. To accomplish this, the following procedures have been developed to provide guidance to the Principle Investigator in adequately decommissioning the laboratory they are vacating.
- Inventory all chemicals in the laboratory and ensure Material Safety Data Sheets are available.
- Label all chemicals with the appropriate information including name, manufacturer, hazard warnings, and required personal protective equipment.
- Cap or seal all containers.
- Contact the Laboratory Manager to arrange return of re-usable chemicals to the Stock Room.
- Fax Hazardous Waste Disposal form to the EHS office at 704-687-5302.
- Segregate chemicals by compatibility.
- Decontaminate all surfaces including fume hoods, lab benches, and equipment.
- When moving chemicals between locations, use secondary containment pans or drums to hold leaks or spills that can occur during transport.
Radioactive Materials and Radiation Producing Machines
- Complete UNC Charlotte RAS Form 7 “Radioactive Waste Disposal Record” and contact Safety Office for removal of waste.
- If transferring radioactive materials to another authorized user, complete UNC Charlotte RAS Form 8 “Notification of Transfer of Radioactive Materials” and submit to the EHS Office.
- Wipe sample areas of highest potential contamination. If samples are 2 times background, decontaminate the surface and wipe sample again.
- Return all film badges and TLD rings to the Safety Office.
- Complete and return the following forms:
a. UNC Charlotte RAS Form 4 “Radiation Survey Report”
b. UNC Charlotte RAS Form 6 “Radioactive Material Inventory Record”
c. UNC Charlotte RAS Form 7 “Radioactive Waste Disposal Record”
d. UNC Charlotte RAS Form 10 “Radiation Producing Machine Utilization Log” (if applicable)
- For radiation producing machines, disconnect the power supply, lock and tag the power source.
- Do not remove any signage, the Safety Office will remove the signs when the decommissioning is complete and acceptable.
- Dispose of biohazardous waste in the appropriate containers.
- Autoclave and decontaminate any glassware or equipment that can be re-used.
- Decontaminate work surfaces and equipment appropriately.
- Place all broken glassware in a glass disposal box.
