Biosafety in Biological and Biomedical Laboratories
  • Marshall University
  • Feb 9 2007
2
Major Safety Concerns
  • General Biosafety
  • Recombinant DNA (rDNA)
  • Management of infectious agents and biohazardous waste
  • Bloodborne Pathogen Exposure
  • Human Subject Protection (IRB, Dr. C. Winger)
  • Radioisotope Use (Dr. W. McCumbee)
  • Use of Animals in Research (Dr. Howard)
  • Chemical Safety (Dr. K. Guyer, Brian Carrico)
3
General Principles of Biosafety
  • Containment:  to reduce or eliminate exposure of lab workers and others to hazardous biological agents
    • Bacteria, viruses, fungi, parasites
    • Recombinant DNA
    • Potentially dangerous cell lines
4
General Principles of Biosafety
  • Three elements of containment:
    • Safety equipment (personal protective equip)
    • Facility design
    • Lab practice and techniques
  • Extent of containment depends of level of risk and nature of agent.
5
Examples of Safety Equipment
  • Biological Safety Cabinets (Laminar Flow Hood)
  • Safety Centrifuge Cup
  • Gloves, lab coats, gowns, face shield, goggles, shoe covers, respirators
6
Four Biosafety Levels (BSLs)
  • Combinations of lab practices and techniques, safety equipment and lab facilities
  • Appropriate for operations performed and routes of transmission of infectious agents/rDNA
  • BSL1-4 represent conditions under which the agent can be safely handled
7
Biosafety Levels 1-2
  • BSL 1: appropriate for work with organisms known to not cause in healthy adult humans.
    • E coli,  Bacillus spp,
    • Exempt categories of rDNA work
  • BSL 2: indigenous moderate risk agents.
    • Primary Hazard: Skin break, mucous membrane exposure or ingestion.  Examples
    • Hepatitis B, HIV, some Salmonellae
    • Human derived blood and blood products
    • Cell culture work and some rDNA
8
Biosafety Levels 3-4
  • BSL 3:  work with indigenous or exotic agents with potential for respiratory transmission or lethal consequences.
    • Examples: M. tuberculosis, St. Louis encephalitis virus
    • Primary and Secondary barriers to protect personnel in contiguous areas
  • BSL 4:  lethal exotic agents esp. where there is no vaccine or therapy.  Marburg Virus
    • BSL 4 facility is separate facility or HVAC isolated zone
9
BL 1 practices:
Standard Microbiological Practices
  • Access to lab is limited or restricted when experiments are in progress
  • Workers wash hands after handling viable organisms, after removing gloves and before leaving the lab
  • Eating, drinking, smoking, handling contact lens, brushing teeth, storing food is absolutely forbidden.
  • Inspectors routinely look through the regular trash.
10
BL1 practices, part 2
  • Mouth pipetting is prohibited- must use mechanical pipetting devices
  • Safe handling of sharps (disposal)
  • Procedures minimize splashing and aerosols
  • Decontaminate work surfaces on a daily basis
  • All cultures, stocks and other infectious materials are decontaminated by an approved method (usually autoclaving).
  • Biohazard signs are posted at lab entrance.
  • Insect and rodent control program in place.
11
Biosafety Level 2
  • Similar to BSL-1 and suitable for work with agents of moderate hazard
  • Lab personnel get specific training in  handling pathogens
  • Access to the lab is limited when work is being conducted.
  • Greater precautions taken with contaminated sharps
  • Specific procedures for reducing aerosols or splashes
12
BSL 3 and 4

  • Levels of personal protection increase
  • Access is restricted
  • Lab design becomes more critical
  • Animal Biosafety Levels: special sets of procedures
13
Which Biosafety Level should
you be using in your lab?
  • Discuss specific safety issues with your mentor and safety committee chairs
  • Lab heads should prepare written safety protocols that are lab/experiment specific
  • Read the entire Biosafety in Microbiological and Biomedical Laboratories Section VI or the NIH rDNA guidelines
  • Contact Dr. Primerano at 696-7338
14
General Biosafety Advice
  • Get a lab coat and other safety equipment immediately.
  • Don’t wear open shoes!!!
  • Keep hair short or tied back
  • Glove allergies: nitrile may help
15
Transformed or cancer cell lines
  • Any experiment involving transformed or cancer cell lines falls under Biosafety Level 2 (BL2) practices.
  • This work should be done under a biological safety cabinet.
  • Special precautions are taken to limit aerosols.
  • Cells and media must be treated with 10% bleach before autoclaving.
  • Decontaminate spills with bleach and wipe down hood after working with cells.
  • Protective clothing (lab coat and gloves) should be worn when working with the cells.
  • Restrict access to the lab.
  • See “Safe Handling of Cell Lines” on the IBC web site

The NIH Guidelines
19
The NIH Guidelines Apply to…
  • rDNA research
    • that is funded by the NIH, OR
    • performed at or sponsored by an institution that receives any NIH funding for rDNA research.


  • Means that all rDNA research at MU must comply with guidelines


  • Failure to comply can result in
    • (i) suspension, limitation, or termination of financial assistance for the noncompliant NIH-funded research project and of NIH funds for other rDNA research at the institution, or
    • (ii) a requirement for prior NIH approval of any or all rDNA projects at the institution.


  • Rationale: For biosafety to be meaningful, it has to be observed by all investigators at an institution
20
NIH Guidelines
  • “Guidelines” does not mean “optional”
  • They are one of several conditions of NIH funding
21
rDNA (rDNA)
as defined by the NIH Guidelines
  • rDNA molecules are either
    • Molecules constructed outside cells by joining natural or synthetic DNA segments to DNA molecules that can replicate in a living cell,  OR
    • Molecules that result from the replication of those described above
22
Organization of the NIH Guidelines
  • Section I – Scope
  • Section II – Safety Considerations
  • Section III – Types of Experiments Covered (6)
    • IIIA – IBC Approval, RAC Review, NIH Director Approval Mandatory

Risk Group Classifications
  • Agents are classified according to their relative pathogenicity for healthy adult humans (from least to most pathogenic)


  • Risk Group 1 (RG1) agents are not associated with disease in healthy adult humans.


  • Risk Group 2 (RG2) agents are associated with human disease which is rarely serious and for which preventive or therapeutic interventions are often available.


  • Risk Group 3 (RG3) agents are associated with serious or lethal human disease for which preventive or therapeutic interventions may be available.


  • Risk Group 4 (RG4) agents are likely to cause serious or lethal human disease for which preventive or therapeutic interventions are not usually available.
25
ABSA Web site
  • If don’t which risk group your agent falls into:


  • Call or email Don Primerano OR
  • Consult the ABSA website:

    • Potential risk to environment and public health
  • What do IBCs assess in reviewing rDNA research?


    • Containment levels per NIH Guidelines


    • Adequacy of facilities, SOPs, PI and lab personnel training


    • Institutional and investigator compliance; e.g., adverse event reports
37
P.I. Responsibilities
  • Determine the category of rDNA research
  • Submit rDNA applications if and when necessary
  • Report problems or violations to the IBC
  • Report issues with the NIH Guidelines
  • Be trained in good microbiological techniques and provide training in lab specific protocols to all lab personnel
  • Adhere to IBC approved plans for handling cell lines and spills
  • Comply with all facets of the rDNA guidelines including shipping requirements


38
IBCs and Exempt Research
  • Who determines whether research is exempt?


  • A matter of institutional policy according the guidelines.
  • At Marshall, the PI (lab head) makes the determination whether a protocol falls into the exempt category
  • If you as PI decide that a given protocol is exempt you do not need to complete an rDNA application BUT you must notify the IBC Chair by email.  Give a short description of the protocol and tell why it is exempt.
  • NIH OBA and IBC Chair can help with determinations


39
rDNA Regulations
and Biosafety Levels
  • Select BSL1-4 based on the category and specific nature of your protocol.
    • Example: work with RG2 organisms must be conducted at BL2.
    • Consult rDNA guidelines in all cases.
  • BL1+BL2 are appropriate for much rDNA work at Marshall (but not all).
  • A minimum of BL1 should be used even for exempt protocols.
  • Each investigator must be familiar with the guidelines.
