Reporting mandatory for manufactured/imported microorganisms if not found on the Domestic Substances List
Research & development exempted (OK in the lab and with no release in the environment): Reporting required if organisms
are introduced into experimental field study without containment

Biohazards Policy*
“Prior to beginning work with biohazardousmaterial, responsible users must complete and submit an Application to Use Biohazardous Materials to Environmental Health & Safety for review and approval”
*University Laboratory Safety Committee September 24, 2007

Bacteria Viruses Fungi Parasites Plants and algae Prions
Environmental Health & Safety
Biohazards
Toxins of biological origin Human tissue, blood, body fluids Animal tissues, carcasses Nucleic acids Genetically modified strains & organisms Others that could contain biohazardous
material, e.g. Cell lines Cultures from soil samples Waste water
Environmental Health & Safety
LAI*: Routes of Transmission
Origin: biological, chemical, or radioactive Direct contact (e.g. splash, spills) Inhalation Ingestion Dermal entry Parenteral inoculation (injection) Indirect contact (i.e. touching a contaminated
door handle)
Vectors: animal/insect bites
*Laboratory acquired infections (LAI) or exposures
Environmental Health & Safety
Risk Groups Categorization of relative hazards of infective
organisms (4 levels) Risk Groups 1, 2, 3 & 4
Risk classification: Pathogenicity Infectious dose Mode of transmission Host range Effective prevention (e.g. vaccine) Effective treatment (e.g., antibiotic, antiviral PEP)
Environmental Health & Safety
Containment Level
Minimum requirements for safe handling (4 levels) Operational practices
Safe work practices Engineering, technical, physical:
Location & access Surface finishes & casework HVAC Containment perimeter (windows, autoclave
location, etc.) Services (water, drains, gas, electricity,
equipment)
Environmental Health & Safety
Containment Level 1
No special design features Biological safety cabinet not required, may be
used for sterility Work may be done on open bench top Good aseptic/microbiological technique
Environmental Health & Safety
Containment Level 2
Additional physical requirements, e.g. Limited access, signage, lockable doors Resistant, non-absorptive surfaces (for disinfection)
Containment of aerosols: Biological safety cabinets Centrifuges with sealed rotors or safety cups
Minimize environmental contamination: Hand washing sinks Decontamination facilities (e.g. autoclaves)
Environmental Health & Safety
Containment Levels 3 and 4 Level 3 Respiratory protection HEPA filtration of lab exhaust Strictly controlled access
Level 4 Isolated facility with sealed perimeter Positive pressure suits or Class 3 BSC Effluent sterilization system

WHMIS*
*Workplace Hazardous Materials Information System
ObjectiveTo ensure the protection of workers and students from the adverse effects of hazardous materials through the promotion of access to health and safety information on Controlled & Hazardous Products
Environmental Health & Safety
WHMIS - Classes
D2 -Materials Causing Other Toxic Effects
A – Compressed Gases
B – Flammable & Combustible
C- Oxidizing Material
D - Poisonous & Infectious Materials
D - Poisonous & Infectious Materials
D - Poisonous & Infectious Materials

Canadian Nuclear Safety Commission(CNSC) The acquisition, possession and use of radiation
sources are subject to licensing by the CNSC EHS administers the CNSC license, renewed every 5
years. Internal permits are issued by EHS to radiation users
(renewed yearly) after completing the Application to Use Radioactive Materials
Internal permits contain: Name of permit holder; Classification of laboratory (e.g. Basic, Intermediate, High); Validity period; Approved use and/or storage locations; Radioisotope types and possession limits; Certain compliance conditions.
