University of Kentucky Department of Biological
Safety
2
Biological Safety Training
  • Module 1 Basics of Biosafety
  • Module 2 Risk Assessment
  • Module 3 Working with Infectious Agents
  • Module 4 The Biosafety Levels
  • Module 5 The Biosafety Audit

3
Biosafety Levels
  • Do you know your labs biosafety level?
  • What are the proper procedures and practices for
    your biosafety level?
  • How does waste need to be decontaminated at your
    biosafety level?

4
Biosafety Practices and Procedures
  • The University of Kentucky adheres to the
    guidelines presented in the CDC publication,
    Biosafety in Microbiological and Biomedical
    Laboratories
  • Each laboratory is required to have a copy
    available as a paper version or a webpage link on
    the laboratory computer
  • http//www.cdc.gov/od/ohs/biosfty/bmbl5/bmbl5toc.h

Biological Safety Levels in the Lab
6
Biosafety Levels at UK
  • Registration with the Department of Biological
    Safety is required for BSL-1 projects
  • Approval from the Institutional Biosafety
    Committee (IBC) is required for BSL-2 and BSL-2
    projects
  • Approval from the IBC and possibly other entities
    is required for BSL-3 projects
  • BSL-4 projects are not allowed at UK

Biosafety Levels Build on Each Other
7
Procedures and Practices for BSL-1 Labs
  • Wash hands often
  • Know location of safety showers and eyewashes
  • Wipe down work surfaces with disinfectant daily
    and after spills
  • No eating, drinking, smoking, applying cosmetics,
    handling contact lenses

8
Procedures and Practices for BSL-1 Labs
  • Label biohazard use and storage areas
  • Decontaminate waste prior to disposal
  • Keep the laboratory neat and organized
  • Proper sharps and broken glass disposal is in
    place

9
Procedures and Practices for BSL-1 Labs
  • Mouth pipetting is prohibited
  • Access to the laboratory is limited during
    experiments
  • Doors are locked when the laboratory is
    unoccupied
  • Work is performed carefully to minimize splashes
    and aerosols

10
Personal Protective Equipment for BSL-1 Labs
  • No Sandals, No Shorts
  • Lab Coats worn only in lab
  • Gloves as needed for procedures
  • Protective eyewear if splashes are anticipated

11
Procedures and Practices for BSL-2 Labs
  • All BSL-1 practices are followed, plus
  • Access is restricted and laboratory doors are
    labeled when work with infectious agents is
    performed
  • All personnel working in the lab must have
    adequate lab-specific training
  • Appropriate immunizations are received if
    available

12
Procedures and Practices for BSL-2 Labs
  • Nothing stored in the biosafety cabinet and
    anything used in the biosafety cabinet properly
    decontaminated before removal.
  • Sharps and glassware should be avoided if
    possible
  • Substitute plastic for glass
  • Use safer sharps
  • Self-sheathing needles

13
Procedures and Practices in a BSL-2 Lab
  • Approved secondary container utilized
  • for transport.
  • Sealed centrifuge buckets or rotors preferred.
  • Aspiration used with proper trap and filter setup.

14
Safety Equipment in a BSL-2 Lab
  • Biological Safety Cabinets are utilized
  • Nothing stored in the biosafety cabinet and
    anything used in the biosafety cabinet properly
    decontaminated before removal.
  • Personal Protective Equipment
  • Gown
  • Gloves
  • Face and Eye Protection

15
Practices and ProceduresBSL-2 Lab
  • Sharps not used to harvest virus solution or for
    culture of infected cells.
  • Aspiration not used with infected cultures or
    proper trap and filter setup utilized.
  • Properly dispose of sharps
  • Call Environmental Management (3-6280) for
    disposal if laboratory located outside of the
    Hospital or Medical Sciences Building

16
Practices and ProceduresBSL-2 Lab
  • The door to the culture room will remain closed
    at all times and only necessary personnel will be
    permitted to use the room when experiments with
    infectious agents are being performed.

17
Practices and ProceduresBSL-2 Lab
  • One-glove rule utilized for transport of
    materials to centrifuge.
  • Approved secondary container utilized for
    transport of infectious agent.
  • Centrifuge buckets or sealed rotors opened/closed
    only in BSC and the outside is decontaminated in
    BSC.
  • Cultures housed in a dedicated and labeled
    incubator.

18
Personal Protective Equipment in BSL2 Lab
  • Face Shield/Safety Goggles and Face Mask for
    Splash Protection Outside BSC
  • Respiratory Protection as needed
  • Disposable Wraparound Lab Gown
  • Double Gloves
  • Standard lab safety dress code will be followed
    (no shorts or open toed shoes, etc.) as required
    by OSHA.

19
Practices and ProceduresBSL-3 Lab
  • A lab specific biosafety manual addressing all
    precautions and procedures must be in place
  • Negative pressure, HEPA filtered exhaust air is
    utilized in the facility
  • All penetrations in outer walls sealed
  • Entry is through double self-closing doors
  • BSL-3 facilities must be tested and verified for
    containment

20
Personal Protective Equipment in BSL-3 Lab
  • Lab-specific risk assessments can determine
    appropriate PPE
  • Additional protective equipment may be necessary
    in a BSL-3 facility
  • Detailed standard operating procedures are
    written for entering and exiting the facility and
    PPE required

21
Personal Protective Equipment in BSL-3 Lab
  • Respiratory protection may be necessary depending
    upon risk assessment
  • Extra layer of PPE required for work with
    infected animals

22
Decontamination and Waste Disposal Procedures
  • In BSC, all disposables are either inactivated
    with 0.5 sodium hypochlorite or placed in an
    autoclavable cardboard box when working with
    infectious materials.
  • The box placed in an autoclave bag, the outside
    of the autoclave bag decontaminated, bag removed
    from the biosafety cabinet and put into another
    autoclave bag to be autoclaved under appropriate
    conditions.

23
Decontamination and Waste Disposal Procedures
  • BSC surfaces thoroughly wiped with disinfectant.
  • Biohazard Waste Containers
  • hard-sided
  • foot operated lid
  • easily decontaminated with liquid disinfectant
  • only the inside of the autoclave bag is visible

Types of waste
25
What is Medical Waste?
  • Definition Medical waste is generally defined
    under state regulations. Medical waste is often
    described as any solid waste that is generated in
    the diagnosis, treatment, or immunization of
    human beings or animals, in research pertaining
    thereto, or in the production or testing of
    biologicals, including but not limited to
  • blood-soaked bandages
  • discarded surgical instruments - scalpels
  • needles - used to give shots or draw blood
  • removed body organs - tonsils, appendices, limbs,
    etc.
  • lancets
  • intentionally infected animal carcasses

26
Autoclaving Biohazardous Waste
  • Wear buttoned lab coat, eye protection,
    closed-toed shoes, heat resistant gloves.
  • Add 1 liter of water to properly vented clear or
    orange autoclave bag by pouring carefully down
    the side of the bag
  • Use a solid secondary container or pan approved
    for autoclave use
  • Promptly remove cooled autoclaved biohazardous
    waste to trash
  • Record use in user log
