Collect materials contaminated with biological agents in appropriate containers and follow the procedures below for either containment level 1 or 2 labs..
Biological waste includes:
- All biological material or products thereof, whether considered hazardous or not. "Harmless" microorganisms can be harmful to immunocompromised individuals.
- Liquids such as used cell culturing media, supernatant, blood or blood fractions (serum) etc., which contain viable biological agents.
- Any part of an animal infected (or suspected to be infected) with a communicable disease
- Non-sharp, solid laboratory waste (empty plastic cell culture flasks and petri dishes, empty plastic tubes, gloves, wrapper, absorbent tissues, etc.) which may be, or is known to be, contaminated with viable biological agents.
- All sharp and pointed items used in medical care, diagnosis, and research, including the manipulation and care of laboratory animals, which are considered potentially infectious.
- Laboratory glassware which is known or suspected to be contaminated with hazardous biological agents.
Containment Level 1 Labs
- Waste should be handled as non-hazardous (except when dealing with needles or if the waste contains Chemical or Radiation hazards).
- Put waste into non-hazardous labelled autoclave bags supplied through MedStores.
- DO NOT OVERFILL THE BAGS.
- Seal the bags but leave room for steam to enter and exit.
- Place the bag in an autoclave bin, found near the autoclaves, and place the bin in the autoclave.
- After autoclaving, remove the bin, using oven gloves, and cool for several hours before placing the bags in the garbage.
Containment Level 2 Labs
- Waste (including blood, tissue, bacterial plates and biologically contaminated gloves, pipettes and other garbage) must be placed in yellow plastic Bio waste 20L pails.
- The bags are twist-tied or taped shut and put into an autoclave basin.
- After autoclaving both the Biosafety Certificate number and room number must be marked visibly on the bag.
- The material will be picked up by the hazardous waste technicians. To arrange for a special pick up, contact Environmental Protection Services - Bio Waste at 416-946-3473 or email email@example.com.
- The material is then sterilized and the process validated off-site.
Mixed paper [copy, binder, computer, fax, and fax paper, text books, newspapers, magazines, clean paper towels, clean napkins, clean tissue, empty paper bags, bristol board, illustration board, boxboard (i.e. tissue, ink jet cartridge, cereal, snack boxes, etc.)] can be placed in:
- Your blue desk-side recycling containers (You are required to empty your own container into a nearby blue toter);
- Blue box in work areas and labs;
- The 4 compartment depots located inside the building; or
- The large, blue toters located in the hallways.
For office clean out call 416-946-9511 to request the loan of a blue toter.
