26.1 General Biosafety Policy

Work with biological material at Berkeley Lab is conducted in a safe, ethical, environmentally sound, and compliant manner using the principles and functions of Integrated Safety Management (ISM) and work authorization (PUB-3000, Chapter 6).  For the purpose of this policy, biological materials encompass a broad range of organisms, cells, viruses, and other materials of biological origin that pose differing levels of risks to plants, animals, or humans.  Line management and researchers are expected to define their biological work, evaluate the biological hazards, determine the risk, and implement required biosafety containment controls (i.e., establish a Biosafety Level).  This is accomplished with the assistance and oversight of the Institutional Biosafety Committee (IBC), the Environment, Health, and Safety Division (EH&S), and other Berkeley Lab ES&H functions.  The Biological Use Notification, Registration, and Authorization process is used to facilitate and document the above process and ensure compliance.

Berkeley Lab’s policy incorporates required federal and state government, contract, and funding regulations and standards.  This chapter provides an overview of biosafety policy to assist in identifying and understanding the requirements for evaluation and control of biological work in research.  LBNL’s policies and requirements for work with biological material are further detailed in the online Biosafety Program and Biosafety Manual.

26.2 Biological Risk and Requirements

Identification of biological risk and requirements associated with an operation must consider three primary factors:  the inherent hazard (perceived or real) posed by the biological material or agent, the susceptible hosts (i.e., receptors) that may be affected by the material or agent, and the exposure pathways between the threat hazard and the susceptible host.  This section discusses these factors and provides an overview of biological risk and hazard categories, biosafety standards, and associated requirements.

26.2.1 Risk Assessment and Groups

The term “biohazardous” is used to describe biological materials that present potential risk to the health of humans or other organisms, either directly through infection or indirectly through damage to the environment. 

To define the risk associated with a biological agent, the researcher must make an initial risk assessment based on the Risk Group (RG) of the agent.  Four Risk Groups (RGs) have been defined by the World Health Organization (WHO) and adopted by the Centers of Disease Control and Prevention (CDC).  These Risk Group categories are defined by the National Institutes of Health (NIH) in Appendix B of the NIH Guidelines for Research Involving Recombinant DNA Molecules.  These NIH Risk Group definitions are based on risk of disease in humans and are shown in Table 26-1Assignments of specific agents to Risk Groups can also be found in Appendix B of the same document or in other sources such as the American Biological Safety Association (ABSA) risk group database.  Risk Group definitions and classification may vary slightly between countries.  Berkeley Lab uses the NIH Risk Group definitions and agent classifications. 

Table 26-1  Risk Groups and Definitions

Risk Group

Risk Group Definition

1

Agents that are not associated with disease in healthy adult humans. 

2

Agents that are associated with human disease that is rarely serious, and for which preventive or therapeutic interventions are often available.

3

Agents that are associated with serious or lethal human disease for which preventive or therapeutic interventions may be available (high individual risk but low community risk).

4

Agents that are likely to cause serious or lethal human disease for which preventive or therapeutic interventions are not usually available (high individual risk and high community risk).

When deciding the appropriate containment for the biological work, consideration should be given to the Risk Group assignment, agent factors, how the agent is to be manipulated, and if medical surveillance is required.  Agent factors that should be considered include: virulence, pathogenicity, infectious dose, environmental stability, route of spread, and communicability.  Manipulations that should be assessed include: handling operations (e.g., use of sharps), quantity of agent, and aerosol generation.  Medical surveillance factors may include: availability of vaccine or treatment, physiological activity, and allergenicity.  Any recombinant biological material that is known to be more hazardous than the parent (wild-type) may require handling at a higher containment level.

26.2.2 Bloodborne Pathogens and Human Materials

Bloodborne pathogens (BBPs) are infectious agents that are capable of causing human disease and are transmitted through human blood and tissues.  Examples include the hepatitis B virus (HBV) and the human immunodeficiency virus (HIV).  According to the Federal Occupational Safety and Health Administration (OSHA) BBPs Standard, materials that are regulated based on their potential to contain BBPs include human blood, human blood components, products made from human blood, and other potentially infectious materials (OPIM) listed in Table 26-2.  Work that may involve exposure to these human materials is conducted at Biosafety Level 2 containment (see Section 26.3) and requires compliance with the specific requirements of the Fed/OSHA BBPs Standard.  Dried blood and some human secretions (e.g., urine, feces, vomit, tears, sweat, sputum, nasal secretions, and saliva) that do not contain blood are not considered OPIM.

Table 26-2  Human and Other Materials Covered by the OSHA Bloodborne Pathogens Standard*

Blood, including human blood, blood components, and products made from human blood

Other Potentially Infectious Materials (OPIM):

  • Unfixed Human Tissue or Organ (other than intact skin) from a living or dead human.
  • Primary Human Tissue Cultures.  These cultures are explants of living human tissue placed in a medium for tissue culture.
  • Primary Human Cell Strains.** These cell strains are propagated in vitro from primary explants of human tissue or body fluids that have a finite lifetime (i.e., nontransformed) in tissue culture for 20 to 70 passages.
  • Established Human Cell Lines.**  These cell lines are immortalized cells that have been transformed by spontaneous mutation or natural or laboratory infection with an immortalizating agent, and then propagated or passaged many times (e.g., in vitro or in animals such as mice).
  • Human Body Fluids.  Fluids that are assumed to be potentially infectious include semen, vaginal secretions, cerebrospinal fluid, synovial fluid, pleural fluid, pericardial fluid, peritoneal fluid, amniotic fluid, saliva in dental procedures, any body fluid that is visibly contaminated with blood, and all body fluids in situations where it is difficult or impossible to differentiate between body fluids.  Some human secretions that do not contain blood are not considered OPIM (e.g., urine, feces, vomit, tears, sweat, sputum, nasal secretions, and saliva).
  • HIV or HBV Infected Materials.  HIV-containing cell or tissue cultures, organ cultures, and HIV- or HBV-containing culture medium or other solutions; and blood, organs, or other tissues from humans or experimental animals infected with HIV or HBV.

Footnotes:

*  Text taken from OSHA BBP Standard 29 CFR 1910.1030 and the OSHA Standard Interpretation on Applicability of 1910.1030 to Establish Human Cell Lines.
** Most primary human cell strains and established human cell lines at LBNL (e.g., ATCC cell lines) are OPIM as required by the OSHA Standard Interpretation on such cells.  If the researcher does not want to consider the cells OPIM, the cells must be “characterized.”  Characterization must include documented screening of the cell lines or strains for viruses specified as BBPs in the Standard, including human immunodeficiency viruses, hepatitis viruses, and herpes viruses (e.g., Epstein-Barr virus), if the cells are capable of propagating such viruses.  Documentation that the cell line in culture is free of BBPs must be reviewed and approved by the Biosafety Officer and Institutional Biosafety Committee.

26.2.3  Recombinant Organisms and Genomic Materials

Work with recombinant organisms or specific recombinant genomic materials and nucleic acids may involve risks to humans, animals, plants, or the environment.  Requirements for work with recombinant DNA molecules are specified in the NIH Guidelines for Research Involving Recombinant DNA Molecules (NIH Guidelines), and recombinant DNA molecules are defined in Section I-B.  Institutions such as LBNL that receive NIH funding are required to comply with the NIH Guidelines.  As a condition for NIH funding, LBNL and researchers must ensure that all recombinant DNA research conducted at or sponsored by LBNL, irrespective of the source of funding, complies with the NIH Guidelines.

26.2.4  Pathogenic and Etiologic Agents

26.2.4.1 Pathogens and Virulence

Pathogens are infectious microbial (e.g., bacteria, protozoa, fungi, viruses, etc.) or other agents that can cause disease in healthy host organisms such as humans, animals, or plants.  “Opportunistic pathogens” may become pathogenic on their own or by infecting immuno-compromised hosts.  Avirulent or attenuated agents are pathogens that were physiologically modified or genetically altered in a way that they are several orders of magnitudes less likely to produce disease in a healthy host organism.  Pathogens may be regulated by a variety of agencies (e.g., OSHA, NIH, CDC, USDA) depending on the potential hosts and impacts (e.g., humans or livestock).

26.2.4.2 Biological Etiologic Agents

A “biological etiologic agent” is an agent of biological origin (e.g., bacterium, fungus, parasite, virus, etc.) that causes disease in humans (i.e., pathogenic to humans).  See Appendix B of the NIH Guidelines for a list and Risk Group categorization of human etiologic agents.

This section describes specific requirements and programs for biological etiologic agents that are included in LBNL’s biosafety program, as required by the DOE Worker Safety and Health Program (10 CFR 851, Appendix A, Section 7).  Line management is responsible for reporting work with biological etiologic agents.  The Institutional Biosafety Committee (IBC) and EH&S Division have specific oversight and reporting responsibilities listed in the following sections.

26.2.4.2.1  Institutional Biosafety Committee

Berkeley Lab has an established IBC that has the following responsibilities related to biological etiologic agents:

26.2.4.2.2  EH&S Division

The EH&S Division has the following responsibilities related to biological etiologic agents:

26.2.5  Select Agents and Toxins

The term “select agents and toxins” is used to describe the list of specific pathogenic agents and toxins that are strictly regulated by the CDC and USDA, because they may potentially be used as biological weapons or pose a severe threat to human, animal, and plant health.  Specific genetic elements, recombinant nucleic acids, and recombinant organisms that may pose a similar threat are also regulated. 

26.2.5.1  Select Agent and Toxin Requirements

Possession, use, or transfer of select agents and toxins must be conducted in compliance with the CDC and USDA regulations related to human, plant, and animal select agents and toxins.

26.2.5.2  Select Agent Reporting to DOE

Select agents are defined in Section 26.2.5.  The LBNL EH&S Responsible Official or Alternate Responsible Official for select agents submits to the DOE Berkeley Site Office (BSO) the following select agent notifications as required under the DOE Worker Safety and Health Program (10 CFR 851, Appendix A, Section 7):

26.2.6  Animals, Plants, and Soils

Some organisms, agents, or materials may significantly harm domestic or native animals and plants, or U.S. agricultural and natural resources.  These biological materials are regulated by the U.S. Department of Agriculture (USDA) and require permitting (e.g., soil or import permit) because they may cause harm directly (e.g., predator or pathogen) or indirectly (e.g., vector).  General examples include specific animals, plants, animal pathogens, plant pathogens, materials that may contain such pathogens (e.g., soil), and agents that pose a severe threat.

26.3 Biosafety Containment Levels

Based on the evaluation of biological hazards related to the work, a biosafety containment level and specific work practices shall be established and implemented for the operation.  Biosafety containment levels consist of combinations of standard microbiological practices, safety equipment, and facilities needed to properly contain the biological work.  Biosafety Levels (BLs) are defined in the LBNL Biosafety Manual and are based on the Biosafety Level requirements in the NIH Guidelines (Section II-B, Appendix G, and Appendix I) and the Biosafety Level guidelines in the CDC/NIH Biosafety in Microbiological and Biomedical Laboratories.  Agents requiring implementation of BL3 or BL4 currently are not used or stored at Berkeley Lab.

26.4 Biological Work Review, Documentation, and Authorization

Researchers and line management are expected to define their biological work, evaluate the biological hazards, implement biosafety containment controls, and ensure their work is authorized.  This is accomplished with the assistance and oversight of the Institutional Biosafety Committee (IBC), EH&S Division (e.g., biosafety and hazardous waste management programs), and other Berkeley Lab ES&H functions.  See Table 26-3 for a summary of the review, documentation, and authorization requirements for work with biological materials.  The paragraphs below provide additional explanation.

26.4.1  General Process

The Principal Investigator (PI) and line management are responsible for ensuring that research with biological material is documented, reviewed by the IBC, and authorized when and as required.  Submission and authorization of documentation results in a Biological Use Notification, Registration, or Authorization as detailed in Table 26-3.  LBNL forms are available for this purpose.  Other documentation may also be required.  EH&S Biosafety Program personnel assists the PI in screening the work documentation, determining the applicable requirements and documentation, and coordinating the IBC review process.

The PI is responsible for keeping the work documentation updated, and submitting it for review to the EH&S Biosafety Program either according to the renewal cycles shown in Table 26-3 or when there are significant changes in the work (e.g., addition of recombinant DNA work, addition of pathogens, new types of biohazardous materials, change of location, or change of responsible personnel).  If the changes in work are not significant and the IBC reviewed the document less than three years prior, the EH&S Biosafety Program may approve and distribute the updated document without IBC review. 

26.4.2  Biological Use Notification

A Biological Use Notification is used for work that involves only Risk Group 1 biological material or recombinant material that is exempted by NIH, and does not involve other conditions that require review as listed in Table 26-3.  The PI-authorized Biological Use Notification must be submitted to the IBC simultaneously with experiment initiation, and must receive concurrence by the Biosafety Officer or IBC Chair.  This notification process at the start of a project serves to define and assess the work, establish containment levels, and ensure that the requirements and hazards for the project are correctly identified and addressed.

26.4.3  Biological Use Registration

A Biological Use Registration is required for work with Risk Group 1 recombinant biological materials that are covered by the NIH Guidelines (i.e., recombinant DNA molecules or Risk Group 1 organisms and viruses containing recombinant DNA molecules).  The PI-authorized Biological Use Registration must be submitted to the IBC simultaneously with experiment initiation.  The Biological Use Registration must be reviewed and approved by the IBC.

26.4.4  Biological Use Authorization

A Biological Use Authorization (BUA) is required for biological work that (a) involves biohazardous materials (i.e., Risk Group 2 or higher materials, or the use of Biosafety Level 2 containment for safety), or (b) requires a regulatory registration or permit for the operation (i.e., USDA soil or plant pest permit, select agent registration, etc.).  A BUA is a type of LBNL “Formal Authorization” as defined in Chapter 6 of PUB-3000.  PI-approved Biological Use Authorizations require full IBC review and approval, and authorization by the PI’s supervisor prior to commencing work.

Table 26-3     Berkeley Lab Review, Documentation, and Authorization for Work with Biological Materials

To determine work review requirements or procedures for any given project with biological materials, classify the biological work types in the first column, and then select the highest-level authorization type indicated in the second column.  Generally, work that involves recombinant DNA, Risk Group 2 agents, Biosafety Level 2, or human Bloodborne Pathogen material has more stringent requirements.  In addition, Biological Use Authorizations involve a higher level of review than Biological Use Notifications and Registrations.  Further conditions that determine the level of review include requirements for specific regulatory permits, regulatory registrations, or funding agency assurance.

26.5     Biological Waste

Guidance for the disposal of hazardous waste is provided in Chapter 20 (Hazardous Waste Disposal) of PUB-3000.  Specific guidance for the disposal of medical or biohazardous waste is provided in the Medical and Biohazardous Waste Generator’s Guide (PUB-3095).  Generally, when biohazardous waste is to be rendered noninfectious, the process is accomplished either by the addition of bleach (i.e., sodium hypochlorite) to biological liquids, or the treatment of solid waste by the LBNL biohazardous waste subcontractor.  Refer to the Solid Medical Waste Disposal Procedures chart for a summary of solid waste disposal.

26.6     Biosafety and Waste Training

Supervisors and principal investigators (PIs) are responsible for ensuring their workers have sufficient skills, knowledge, and ability to do their work.  In addition, supervisors and PIs must ensure workers have sufficient job-specific training on the work tasks to be performed, hazards of the specific biological materials that may be present, and biosafety containment to be used.

Specific biosafety or biohazardous waste courses are also required.  At a minimum, anyone working with biological material of any risk level (e.g., microorganisms, cells, cell lines, tissue cultures, recombinant nucleic acids, blood, body fluids or tissues, or animals) must attend EH&S course EHS 739 (General Biosafety Training).  In addition, EHS 730 (Medical/Biohazardous Waste Training) is recommended for anyone working with biological material, and required for anyone generating medical or biohazardous waste. EHS 730 is available as online training or classroom training.  Anyone working with human blood or blood products, or human materials (e.g., cells, tissues, or fluids) considered “Other Potentially Infectious Materials” under the OSHA BBP Standard (see Section 26.2.2) must also take EHS 735 (Bloodborne Pathogen Training).  This latter course requires annual refresher training, termed EHS 738.  EHS 739 and 738 are also available as Web-based challenge exams.

26.7     Biosafety or Waste Questions

For concerns regarding the handling and use of biohazardous materials, contact the EH&S Biosafety Officer at extension 2768 (495-2768).  Questions regarding biohazardous or medical waste may be directed to the Medical Waste Coordinator, extension 7663.  For related medical information, call the Health Services Group, extension 6266.
