2. Office of Environmental Health and Safety Objectives  Minimize amounts of waste produced for disposal  To be able to SAFELY handle chemical, radioactive and biological wastes produced as a result of research and teaching activities  Know who Environmental Protection Services (EPS) are  To know where to get the information you need on hazardous waste disposal

3. Office of Environmental Health and Safety Waste Minimization In 2013 U of T produced : 138,000 Kg of Chemical waste, costing $ 377,000 to disposal of. 22 m 3 (~25,000 kg) of Radioactive waste, costing $ 175,000 to disposal of. 36,000 Kg of Biological waste, costing $ 141,000 to disposal of. How can you help?  Purchasing practices  Process modification [less chemicals used or even eliminated]  Not mixing with hazardous wastes  Substitution - less hazardous alternatives ? E.g. mercury thermometers replaced with alcohol or electronic

4. Office of Environmental Health and Safety Regulations  All Chemical Waste generation is controlled by the Ministry of the Environment (MOE)  The University has around 64 different generator registrations and each have different waste classes registered

5. Office of Environmental Health and Safety Waste Generators  Each waste generators site has a Waste Generator number (eg. ON0179424)  Waste Classes (eg. 263A, 252L, 331I)  Is specific to an address and site description

6. Office of Environmental Health and Safety What Waste is in your area?  Do you have Chemical waste produced in your area? What types?  Do you have Radiation waste produced in your area? What types?  Do you have Biological waste produced in your area? What types?  Do you know how your waste is handled?  Do you know who to contact for it?

7. Office of Environmental Health and Safety U of T General Requirements Waste handling has the following requirements:  Packaging  Labelling  Storage  Disposal

8. Office of Environmental Health and Safety Typical Chemical Lab Hazards  Flammable  Corrosive  Toxic  Reactives At U of T the most common composition in the research labs is: 75% solvents (most common hazard encountered in labs) 10% acids 15% others such as toxins, bases, oxidiziers etc.

9. Office of Environmental Health and Safety Chemical Waste Packaging  Never mix incompatible materials Fire/Explosion Spill

10. Office of Environmental Health and Safety Chemical Waste Packaging  Sealed containers  Reuse old chemical containers

11. Office of Environmental Health and Safety Chemical Waste Packaging  Liquid Waste containers should only be fill to 75% of capacity to allow for expansion  Don’t use yellow Biowaste pails or the Orange pails from caretaking for collection of chemical waste call for info 978-4821

12. Office of Environmental Health and Safety Chemical Waste Labelling  EPS supplies these labels to the University  Either dropped off in labs or supplies in central waste rooms

13. Office of Environmental Health and Safety Chemical Waste Storage - Local Conditions Some chemicals can become problems by degrading and producing hazardous by- products with:  long storage (e.g. ethers degrade to from unstable organic peroxides)  exposure to water or air (e.g. sodium metal is a solid and stable but when immersed in water produces very flammable hydrogen gas)

14. Office of Environmental Health and Safety Chemical Waste Storage  Waste should be segregated according to compatibility  dispose of ageing containers promptly  DON’T use Bio bags or Radiation bags to collect spill materials or leaking containers!!  Unknowns??

15. Office of Environmental Health and Safety Chemical Waste Storage FUMEHOODS They are a safety device for the protection of laboratory personnel and not as storage areas Defeats the purpose of having a fumehood

16. Office of Environmental Health and Safety Chemical Waste Storage - Local Conditions Each building on campus handles waste storage differently….  Some have designated storage rooms where waste can be move to  Other have to keep in lab to be pickup by Chem Tech

17. Office of Environmental Health and Safety Chemical Waste Disposal Lab staff are responsible for removing chemical waste to their buildings storage room! Make sure container are secure and check for leaks in storage area Illegal to dispose of hazardous chemicals in the sink (Toronto Sewer By-law Chapter 681)

18. Office of Environmental Health and Safety Chemical Waste Storage MSB 5376 ESC 1011

19. Office of Environmental Health and Safety What happens to my Chemicals??  Segregated  Labpacked  TDGA Labels  Loaded

20. Office of Environmental Health and Safety Chemical Waste Disposal – Lab Pickups  Plan ahead!!  Collection done on a first- come-first serve basis  Call-in required for p/u from individual lab  Contractor only on campus 3 days a week so pickups can be delayed up to 2 weeks depending on waste and location!

21. Office of Environmental Health and Safety Chemical Waste Disposal – Lab Cleanout Lab Closures (includes moving or renos) require several weeks to properly deal with potentially hazardous materials. Scheduling Contractors and packaging of the hazardous materials also requires time. 1.Radioactive- Radiation Protection Services (416-978-2028) to arrange for proper decommissioning. 2.Biological- Biosafety Office (416-978-3981) so that the hazard potential may be assessed. 3.Chemical- Environmental Protection Services (416-978-7000) to arrange for the proper disposal of chemicals. 4.Furniture and Room Clean Out- U of T Moving (416-978-0955) to initiate the removal of all remaining equipment and materials. www.ehs.utoronto.ca/services/environmental/labdecom.htm

22. Office of Environmental Health and Safety Chemical Waste Disposal – Lab Cleanout Removal of Chemicals for a lab cleanout should be requested at least 2 week in advance! Chemical Technician will visit the site to review  what NEEDS to be removed  What supplies are need to DO the pickup  check that NO OTHER HAZARDS will affect the pickup Eg. Debris obstructing access to waste

23. Office of Environmental Health and Safety Contaminated Glass and Tips Where do I take contaminated solids? Contaminated Glass including broken Contaminated Plastic including tips Bench cover NO Chemical Solids

Office of Environmental Health and Safety Special Case Chemically-contaminated sharps  Chemicals in trace amounts are to be collected in U of T approved yellow sharps containers  chemicals drained from sharps prior  significant amount of chemical contamination, first deactivated in accordance with MSDS  Contact Biowaste for pickup and disposal 946-3473

27. Office of Environmental Health and Safety Radioactive Waste Management  At U of T, researchers working with any radioactive material, require an internal permit approved by UTRPA, BEFORE work begins.  Only approved permit holders are able to order radioactive materials and must be knowledgeable in University procedures for disposal.

28. Office of Environmental Health and Safety Radioactive Waste Management Definition Includes: – surplus radioactive material – materials that has come into contact with radioactive materials (e.g. gloves, flasks) – used in decontamination (e.g., sponges) – contaminated equipment that cannot be cleaned

29. Office of Environmental Health and Safety Radiation Waste Minimization  Process modification - new less toxic absorbent material used  Not mixing non hazardous with radioactive wastes  developed a delay and decay program for short-lived isotopes

30. Office of Environmental Health and Safety Radioactive Waste Management  Short-lived wastes (< 90 days half life) are allowed to decay in a secure University facility until no longer radioactive then disposed as non radioactive waste.  Long-lived wastes (> 90 day half life) are sent for disposal to permitted facilities. Wastes are removed & packaged by 2 University technicians.

31. Office of Environmental Health and Safety Radioactive Waste Management Packaging  Liquid and solid waste MUST be segregated  containers provided by EPS  Liquid container should be filled to full capacity to maximize absorbent’s potential  Waste packaged in containers that improperly ID other existing hazards  Do not place non rad waste with rad waste

32. Office of Environmental Health and Safety Radioactive Waste Management Labelling Waste not properly labelled will not be removed!! Labels provided free by EPS * Type of label depends on type of waste.

33. Office of Environmental Health and Safety Radioactive Waste Management Labelling - Solid
