Study Notes
Laboratory Biorisk Management
- Laboratory biorisk management is a comprehensive system for controlling safety and security risks in handling biological materials and toxins.
- Core components are risk assessment, mitigation, and performance evaluation.
- Risk assessment involves identifying hazards, evaluating associated risks with biological agents or toxins, and assessing the adequacy of controls.
- Risk mitigation involves actions and controls to reduce or eliminate risks.
- Performance assessment ensures mitigation strategies are effective, using regular monitoring, audits, and feedback loops.
- Biosafety refers to containment principles, technologies, and practices to prevent unintentional exposure to pathogens and toxins.
- Biosecurity focuses on institutional and personal security measures to prevent loss, theft, misuse, or release of pathogens and toxins.
Intended Learning Outcomes
- Students will identify the core components of biorisk management (risk assessment, mitigation, performance evaluation).
- Students will learn about the safe handling, storage, and disposal of biological agents and toxins.
- Students will learn how to mitigate biological risks using layered approaches (engineering controls, administrative measures, PPE).
- Students will apply their knowledge in real-world scenarios like handling infectious waste and sharps.
Importance of Biorisk Management
- Adherence to biosafety and biosecurity practices aligns organizations with internationally recognized standards.
- Raising awareness within research communities promotes safety by expanding awareness of biological risks and their impact on research quality.
- Protecting personnel and their families by preventing laboratory-acquired infections (LAIs) and reducing transmission risks.
- Environmental protection and sustainability by mitigating environmental contamination through proper waste management, and promoting environmental quality and public health.
- Demonstrating a commitment to safety, security, and research integrity by maintaining institutional reputation.
- Enhancing emergency preparedness and response capacity to minimize damage and ensure rapid recovery.
- Preventing loss, theft, or misuse of pathogens, biological materials, and sensitive research data.
- Protecting intellectual property and confidentiality by safeguarding proprietary materials, intellectual property, and confidential research information from unauthorized access.
- Compliance with local, national, and international guidelines (WHO, CDC).
Risks of Handling Biological Materials
- Accidental infection is a risk, due to spills, needle-stick injuries, aerosol generation, or improper handling techniques.
- Accidental release of hazardous substances is possible due to inappropriate containment or improper waste management.
- Intentional theft or misuse of biological agents, toxins, or research information is a concern.
- Physical injuries including cuts, burns, and exposure to hazardous chemicals can accompany biological work.
Laboratory-Acquired Infections (LAIs)
- LAIs occur when laboratory workers are unintentionally exposed and infected.
- About 80% of LAIs are linked to human error such as lapses in safety protocols or improper handling.
- Common LAIs include Brucellosis, Hepatitis, Psittacosis, Q Fever, Tuberculosis, and Tularemia.
Primary Components of Biorisk Management
- Risk assessment: systematically identifying hazards and the risks associated with biological agents or toxins.
- Risk mitigation: reducing or eliminating risks, using engineering controls, administrative procedures, and PPE.
- Performance assessment: ensuring mitigation strategies effectively function, using regular monitoring, audits, and feedback loops.
Key Concepts: Risk Assessment
- Risk is the combination of the likelihood of an event and the severity of resulting harm.
- Factors influencing risk include exposure nature, how individuals are exposed, and harm severity.
- Biological hazard refers to the inherent characteristics of the agent (its infectivity, toxicity).
- Biological risk is defined as the likelihood of an agent causing harm under specific conditions and environment.
- Classification of microorganisms into risk groups 1-4 based on individual and community risk.
Key Concepts: Mitigation
- Mitigation strategies reduce or eliminate risks from handling biological agents or toxins.
- Hierarchy of mitigation controls: Elimination, Substitution, Engineering Controls, Administrative Controls, and PPE.
- Elimination directly removes the hazard (e.g., removing expired cultures), Substitution substitutes a hazard with a less risky alternative.
- Engineering controls isolate the hazards in the environment (e.g., biosafety cabinets), Administrative controls include policies and procedures for safer operations, PPE is the final line of defense providing individual protection.
Key Concepts: Performance
- Performance involves the implementation, evaluation, and continuous improvement of the biorisk management system.
- Control ensures laboratory quality and reliability using validation, verification, and quality control methods.
- Assurance measures involve internal/external audits and inspections.
- Improvement focuses on goal-setting, performance evaluation, corrective actions, and feedback mechanisms for continuous improvement.
