PRAYER BEFORE CLASS Holy Spirit, Divine Creator, true source of light and fountain of wisdom! Pour forth your brilliance upon my dense intellect, dissipate the darkness which covers me, that of sin and of ignorance. Grant me a penetrating mind to understand, a retentive memory, method and ease of learning, the lucidity to comprehend, and abundant grace in expressing myself. Guide the beginning of my work, direct its progress and bring it to successful completion. This I ask through Jesus Christ, true God, and true man, living and reigning with You and the Father, forever and ever. Amen.  UST General Santos Medical Technology Department LABORATORY BIOSAFETY AND BIOSECURITY PRINCIPLES OF MEDICAL TECHNOLOGY PRACTICE 1 Outline PART I PART II History of Laboratory Biosafety and Chain of Infection Biosecurity Classification of Microorganisms According Different Organizations in the Field of to Risk Groups Biosafety Categories of Laboratory Biosafety Basic Concepts on Laboratory Biosafety According to Levels and Biosecurity Classification of Biosafety Cabinets PART III Laboratory Hazards and Accidents Standard Precautions Safe Use and Storage of Chemicals and Reagents Learning Outcome At the end of the unit, the student must be able to: Articulate the importance of biosafety and biosecurity in the field of health sciences.  UST General Santos CHAIN OF INFECTION LABORATORY BIOSAFETY AND BIOSECURITY WHAT IS THE IMPORTANCE OF CHAIN OF INFECTION? WHAT ARE THE COMPONENTS OF CHAIN OF INFECTION? Chain of Infection: 6- Part Model Illustrates how pathogens are transmitted Chain of Infection: 6- Part Model Chain of Infection: 6- Part Model Chain of Infection: 6- Part Model Chain of Infection: 6- Part Model  Chain of Infection: Mode of Transmission DIRECT TRANSMISSION DIRECT CONTACT - Involves actual contact/close proximity of the infected individual and susceptible host - Vertical transmission - Mother to baby transmission - Horizontal transmission - Transmission from a person to another person  Chain of Infection: Mode of Transmission DIRECT TRANSMISSION DROPLET SPREAD - Respiratory particles of moisture containing an infectious agent - Expelled into the air by sneezing, coughing or even talking - Diameter of >5 micrometers and capable only of traveling short distance
