Biohazard Safety

Personal Contamination and Spills

Biosafety Compliance

Compliance with research utilizing biological material is monitored by the Institutional Biosafety Committee. For more information on the rules and regulations for compliance, go to Biological Research.

General Safety
  • Keep lab materials in the lab! This includes pens, personal protective equipment, notebooks, electronics, keys, etc.
    • If you need to take something home, do not bring it into the lab.
  • Be aware of hazards before entering the laboratory.
  • The Safety Data Sheet should be available at all times.
  • Table including frequently used microbes and biosafety levels should be available at all times.
Biosafety level 2
  • Use of moderately hazardous agents
  • Be aware of hazards before encountering an infectious agent
  • Look for signs and symptoms of possible infections/diseases etc.

Differences compared to BSL 1

  • Specific training is required by personnel in handling pathogenic agents, competency testing is also done throughout the laboratory to make sure standards are being met.
  • Laboratory access is restricted
  • BSCs are used anytime an infectious aerosol or splash is being created or used.
  • Special practices are used (see pages 37-43)
  • Slight changes in required equipment
    • Containment use
    • Glove selection based on risk assessment
    • BSC use
  • Changes in work area/facility:
    • Self-closing door
    • Required sink near exit
    • Windows to the exterior are not permitted (if windows are present, they should be fit with screens)
    • BSC installation
    • Vacuum lines need liquid disinfectant traps
    • Required Decontamination plan
Cleaning up a biohazardous spill inside a centrifuge
  • Close off the area and allow aerosols to settle.
  • Notify others including the supervisor.
  • Wait 30 minutes to allow the aerosols created to settle.
  • Don appropriate PPE: laboratory coat, safety glasses, Nitrile gloves.
  • Remove rotors and bucket and place in the sink.
  • Thoroughly disinfect the inside of the centrifuge.
  • Segregate contaminated cleanup materials into the appropriate biohazardous waste containers
