Hazardous Materials Waste Overview
Laboratory research generates hazardous waste. This waste includes a variety of materials such as the by-products of chemical synthesis, biomedical wastes, pump oil and contaminated objects. These wastes require special handling to reduce harmful effects to human health and the environment. At a university, the disposal of a large variety of hazardous wastes can be both difficult and expensive. For all questions regarding hazardous waste in the Faculty of Science please consult the Health, Safety and Risk (HSR) Team.
The disposal of any toxic or hazardous material must be done in accordance with federal, provincial and municipal regulations. Ontario has a comprehensive legislative and regulatory framework to ensure that hazardous wastes are managed in an environmentally safe manner. This system controls collection, storage, transportation, treatment, recovery and disposal of hazardous waste. A few policies are outlined below but please note that the policies outlined are only a subsection of the policies. For more information, please follow the links to the full policies in the References section.
- The University of Ottawa is committed to managing its operations responsibly, in a way that will protect and sustain the natural environment.
- All persons shall comply with directives, procedures and standards established for an activity, by the University, the faculty or service, or by governmental regulatory agencies.
- All persons shall exercise all reasonable care in activities that may pose a risk to the environment.
- 6. (1) An employer shall ensure that a worker who works with or in proximity to a controlled product received from a supplier is informed about all hazard information the employer receives from the supplier concerning the controlled product and all further hazard information of which the employer is or ought to be aware concerning its use, storage and handling.
- (2) An employer who produces a controlled product in a workplace shall ensure that every worker who works with or in proximity to the controlled product is informed about all hazard information of which the employer is or ought to be aware concerning the controlled product and its use, storage and handling. R.R.O. 1990, Reg. 860, s. 6.
- 9. (1) An employer who produces a controlled product in a workplace shall ensure that the controlled product or the container of the controlled product has a workplace label.
General requirement to packing waste
- All materials must be collected in a suitable waste storage container.
- Appropriate containers are available from the waste contractor on the pickup days.
- Each container must be properly labelled to reduce the possibility of mixing incompatible materials. Please see the Label section for more information.
- Incompatible, highly reactive and highly toxic materials must always be packaged separately. This is done to minimize fire and explosion hazards and to ensure the proper handling procedures by the waste contractor. Please contact the HSR Team if you have any questions.
- Each waste container must only have one type of waste material inside. Chemical, biohazardous and radioactive wastes are handled differently and cannot be stored together.
- All 20 Liter containers are to be placed inside a larger secondary container to prevent spillage. The maximum fill line on the secondary containers must be respected to prevent leaking of hazardous waste.
- Whenever liquid waste is put into a container, ensure that the cap has not been full sealed to allow for a pressure release in case of a small chemical reaction.
Chemical Inventory Management System – Vertére
Effective waste management begins with the regular maintenance of a chemical inventory. The University of Ottawa has a chemical inventory system called Vetére Inventory Management System. All chemicals purchased through the Science Store are barcoded and added directly into the Vertére system enabling users to track their chemicals. Furthermore, this system allows for researchers to see the chemicals in other laboratories. The HSR Team can provide assistance in ordering safer and less toxic alternative chemicals if available or to find a chemical that you may be able to borrow in another Faculty of Science laboratory.
Appropriate Waste Containers
1L or 4L
1These containers are reused from liquid chemicals bought in either 1L or 4L glass containers. The labels must be defaced and replaced with an official uOttawa Waste Label
The items in the above table are available for free from the waste contractor or for purchase at the Science Store. For larger volume containers, please contact the HSR team.
Hazardous Waste Labels are required to communicate the contents of all waste containers to laboratory researchers and facility services. Pre-printed labels are available free of charge from the Science Store or from the waste contractor and are typically attached to the waste container. Note that these labels may deteriorate with small drips of chemical waste on the label. Please ensure that the labels are legible when the waste is being picked up.
The following procedure ensures proper labeling, safe handling and collection of hazardous waste:
- Once you begin to collect waste in a new container, immediately attach a “Déchet Dangereux /Hazardous Waste” label to the container.
- As ingredients are added to the container, record the chemical name under the heading “Contenu / Contents”.
- Collect liquid and solid waste in separate containers.
- Further separate the liquid and solid waste by their type of waste.
Characteristics of Hazardous Waste
Hazardous waste is unwanted material which no longer has research value and poses potential threats to public health or the environment. This waste generally exhibits one or more of the following characteristics:
Flammable materials can rapidly vaporise and burn in air. Examples:
- Liquids that have a flash point less than 37.8°C.
- Solids that can cause fire through adsorption of moisture and will burn vigorously and persistently causing a hazard.
- Flammable compressed gases whose vapours ignite easily and rapidly.
Oxidizing materials stimulate combustion of organic materials. Examples:
- Gases – fluorine, chlorine, ozone, nitrous oxide, and oxygen
- Liquids – hydrogen peroxide, nitric acid, perchloric acid, and bromine
Corrosive liquids have a pH of 0-2 or 12-14. Most common acids or bases are corrosive.
- Corrosives can generate corrosive vapours; ensure that the bottles are tightly sealed when transporting them to the waste room.
- Never mix strong acids with strong bases!
Toxic materials can cause damage or death to living organisms. Toxicity of different types of hazardous waste can vary. Examples of toxic substances are compounds containing cyanides or mercury, and pesticides.
- Acute Toxicity is a material that has adverse effects from a single exposure.
- Chronic Toxicity is a material that has adverse effects from repeated exposures.
Unknown Chemical Waste
Please make every effort to identify all waste before submitting an unknown for disposal. This information may greatly reduce the hazards involved in handling and classifying the material. Include the name of the research group, telephone number, type of research, storage method, approximate age of the container and all relevant information (i.e. organic, acid, air reactive, pH, oxidizer etc.). If you are unsure about what to do with your waste, contact the HSR team.
Types of Waste
Liquid Waste should be separated into the following categories and disposed of in a 20L carboys or 1/4L amber bottles. If you are unsure of how to dispose of or segregate your waste, contact the HSR team.
