    Study Notes

    Biosafety Levels

    • BSL-3 involves dangerous and exotic agents that can cause life-threatening diseases, often with no available vaccines or treatments.
    • BSL-2 is typically associated with agents that pose moderate hazards, such as certain viruses that may cause human disease but are not transmitted easily.
    • BSL-1 requires basic containment measures, including standard microbiological practices and minimal safety equipment, suitable for agents not known to consistently cause disease in healthy adults.

    Occupational Health

    • The main focus of occupational health is to promote and maintain the highest degree of physical, mental, and social well-being of workers, addressing various workplace hazards.

    Biosafety and Biosecurity

    • Biosafety aims to protect laboratory workers, the environment, and the public from exposure to infectious agents and hazardous biological materials.
    • Biosecurity refers to measures implemented to prevent unauthorized access, loss, theft, misuse, or intentional release of biological materials.
    • Biosecurity encompasses measures against intentional threats, such as bioterrorism, while biosafety focuses on preventing unintentional exposure.

    Containment Measures

    • BSL-1 containment measures are minimal, relying on standard lab practices, personal protective equipment (PPE), and basic hygiene protocols.
    • BSL-2 requires additional safety measures, including restricted access to laboratories, biosafety cabinets, gloves, and face protection for working with biological agents.
    • BSL-3 necessitates stringent controls, including controlled access, dedicated facilities, and specialized equipment like biological safety cabinets for handling high-risk infectious agents.

    Main Objectives

    • The primary objective of today's presentation is to inform about biosafety and biosecurity measures in laboratories, emphasizing risk mitigation strategies.
    • The main objective of biosafety is to prevent exposure to pathogens, ensuring safety for personnel and the environment while conducting biological research.
    • The primary concern of biosecurity revolves around safeguarding biological materials from misuse or theft, preventing potential threats to public safety.

    Summary of Focus Areas

    • Biosafety focuses on protocols to safeguard against biological hazards, while biosecurity emphasizes protection against intentional misuse and access control.
