Hazardous Waste Management


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


Waste MinimizationIn 2013 U of T produced :

138,000 Kg of Chemical waste, costing $ 377,000 to disposal of.22 m3 (~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


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


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


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?


U of TGeneral Requirements

Waste handling has the following requirements:

Packaging Labelling Storage Disposal


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.


Chemical WastePackaging

Never mix incompatible materials

Fire/Explosion Spill



Sealed containers

Reuse old chemical

containers



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


Chemical WasteLabelling

EPS supplies these labels to the University

Either dropped off in labs or supplies in central waste rooms


Chemical Waste Storage - Local ConditionsSome 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)


Chemical WasteStorage 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??


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


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


Chemical WasteDisposal

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)

What happens to my Chemicals??

Segregated Labpacked TDGA Labels Loaded


Chemical WasteDisposal – 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!


Chemical WasteDisposal – Lab CleanoutLab 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.

Chemical WasteDisposal – 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


Contaminated Glass and Tips

Where do I take contaminated solids?

•Contaminated Glass including broken•Contaminated Plastic including tips•Bench cover•NO Chemical Solids


Chemical Waste HandlingPersonal Protective Equipment

The same precautions for handling hazardous chemicals are applied to chemical wastes

eye protection lab coats gloves


Special CasesGas Cylinders

Treat as high energy sources Use smallest size required to do work Try to use local suppliers Use returnable cylinders

(check before buying) If supplier unable to accept

contact EPS officewww.ehs.utoronto.ca/services/environmental/gascyldispl.htm


Special CaseChemically-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


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.


Radioactive Waste ManagementDefinition

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


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


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.


Radioactive Waste ManagementPackaging

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


Radioactive Waste ManagementLabelling

Waste not properly labelled will not be

removed!!

Labels provided free by EPS

* Type of label depends on type of waste.


Radioactive Waste ManagementLabelling - Solid


Radioactive Waste ManagementLabelling - Liquid


Radioactive Waste ManagementLabelling - Liquid

Green label < 30 days(e.g. P-32, P-33, I-131, Cr-51)

Blue label 30> Half life< 90 days

(e.g. S-35, I-60)

SEGREGATED BY HALF-LIFE OF ISOTOPE

Yellow label > 90 days(e.g. C-14, H-3)


Radioactive Waste ManagementStorage

Each lab should establish one clearly identified location for waste, preferable close to work done with radioactive materials.

Waste should not be stored underneath any working area or near vicinity of people who do not work with radioactive materials.


Radioactive Waste ManagementCollection Schedule

Collection is done on a call-in basis or according to schedule below:

Tuesday: ESC, Pharmacy, MSB 6th & 7th floors, Zoology

Wednesday: Banting, Best, Fitzgerald Thursday: rest of MSB all others when requested

call 978-2050


Radioactive Waste ManagementSpecial Cases Animal Carcasses Gas Chromatographs Gaseous Radioactive Waste Liquid Scintillation Counting Vials (Separate Glass and

plastic) Liquid Scintillation Counters Fridges, freezers or other equipment Sealed sources Shipping materials


Radioactive Waste ManagementSpecial CasesNeedles and Blades

for trace amounts, disposed into special yellow plastic containers approved by U of T and CSA for the disposal of such waste

liquids drained into appropriate colour-coded jars and separately treated as radioactive waste

sharps with significant quantities of an isotope must be disposed as RADIOACTIVE WASTE into separate jars.

These are collect by the Rad Techs (978-2050)


Biowaste Management

Service provided to Biosafety certified Containment Level 2 & 3 Labs

Supply Biowaste 20L Pails, BioTotes, Tags, pickup and information

Biowaste includes biohazardous material, contaminated solids, glass, blades, needles and tips

Pails CANNOT be autoclaved under any circumstances

Wastes are removed by 4 University technicians.

NOTE: Some other labs will need Needle pickups without a Biosafety Certificate


We Take Bags!

DO put in the bags: Soft items: eg. Gloves,

wipes, filter paper Non-sharp plasticware: eg.

eppendorf tubes, tissue culture bottles, petri dishes

DON’T put in bags: Glassware Pipettes Tips Or anything else that could

break or leak from the bag – put these items directly into the biohazard pails.

The University is committed to being environmentally friendly, but we need your help. This will reduce contractor

trips and the amount of plastic going to landfills.

To prevent spills all bags must be double bagged and tied shut. For identification purposes, please write your

Biosafety certificate number on each bag with a marker.
