Biocontamination Course

Lesson 1 • Microbial Agents and Their Properties

Covers bacteria, viruses, fungi, and prions as contamination agents with distinct survival traits. Connects agent properties to transmission and control strategies.

Lesson 2 • Defining Biocontamination and Its Scope

Introduces the formal definition of biocontamination and distinguishes it from chemical and physical contamination. Anchors all subsequent terminology used throughout the course.

Lesson 3 • Transmission Pathways and Vectors

Maps direct and indirect transmission routes including contact, airborne, and vector-borne pathways. Provides the mechanistic basis for contamination prevention design.

Lesson 4 • Host Susceptibility and Infection Dynamics

Examines how host immune status, dose, and exposure duration influence infection outcomes. Builds risk-assessment thinking applied in later chapters.

Lesson 1 • Containment Principles and Hierarchy

Introduces primary, secondary, and tertiary containment layers and their interdependence. Establishes the layered defence model applied in facility and procedural design.

Lesson 2 • Biosafety Level Criteria and Definitions

Defines BSL-1 through BSL-4 criteria based on agent hazard, transmission, and available treatments. Provides the classification framework used in all subsequent risk decisions.

Lesson 3 • Special Categories of Biological Risk

Addresses select agents, dual-use research concerns, and emerging pathogen risks beyond standard classification. Prepares students for complex regulatory and ethical decisions.

Lesson 4 • Risk Assessment Methodology

Guides students through structured risk assessment steps for biological work activities. Produces documented risk assessments required in professional practice.

Lesson 1 • Donning and Doffing Procedures

Provides step-by-step donning and doffing sequences that prevent self-contamination during removal. Reinforces the contamination boundary concept introduced in Chapter 2.

Lesson 2 • Respiratory Protection Systems

Covers filtering facepieces, powered air-purifying respirators, and supplied-air systems for biological aerosols. Connects respirator selection to airborne transmission risk from Chapter 1.

Lesson 3 • Protective Clothing and Glove Systems

Details coverall categories, glove materials, and layering strategies for skin and mucous membrane protection. Addresses chemical compatibility when disinfectants are used alongside PPE.

Lesson 4 • PPE Selection Principles

Establishes criteria for matching PPE type to agent risk level, exposure route, and task duration. Prevents under- or over-protection errors in field and laboratory settings.

Lesson 1 • Facility Zoning and Traffic Flow

Defines clean, transition, and contaminated zones and the directional traffic rules that prevent cross-contamination. Applies containment hierarchy from Chapter 2 to physical space.

Lesson 2 • Facility Inspection and Compliance Auditing

Provides a structured approach to internal facility inspections and audit documentation for biocontainment compliance. Builds the evaluation skills needed for advanced risk management chapters.

Lesson 3 • Biological Safety Cabinets

Covers Class I, II, and III biological safety cabinet types, their protection profiles, and correct use. Reinforces primary containment principles and links to PPE selection from Chapter 3.

Lesson 4 • HVAC and Pressure Differential Systems

Explains negative and positive pressure design, HEPA filtration, and air change rates for biocontainment. Connects airflow engineering to airborne transmission control from Chapter 1.

Lesson 1 • Decontamination of Surfaces and Equipment

Applies inactivation principles to structured surface decontamination workflows for labs, vehicles, and field sites. Addresses porous, non-porous, and complex geometry challenges.

Lesson 2 • Validation and Efficacy Testing

Teaches biological indicator use, coupon testing, and environmental sampling to confirm decontamination success. Produces verifiable records required by biosafety standards.

Lesson 3 • Chemical Disinfectants and Sterilants

Surveys major disinfectant classes, their mechanisms, concentrations, and surface compatibility. Enables evidence-based product selection for specific agents and surfaces.

Lesson 4 • Physical Decontamination Technologies

Covers autoclaving, dry heat, UV irradiation, and vaporised hydrogen peroxide as physical methods. Connects technology choice to agent type and equipment constraints.

Lesson 1 • Laboratory Analysis of Environmental Samples

Surveys culture-based, molecular, and immunological methods for analysing environmental biocontamination samples. Links analytical method choice to detection sensitivity and turnaround needs.

Lesson 2 • Monitoring Programme Design

Establishes sampling objectives, site selection criteria, and frequency schedules for environmental biocontamination monitoring. Connects programme design to risk assessment outputs from Chapter 2.

Lesson 3 • Surface and Water Sampling

Details swab, contact plate, and rinse methods for surface sampling alongside water sampling techniques. Ensures representative sample collection from diverse environmental matrices.

Lesson 4 • Air Sampling Methods

Covers impinger, impactor, and filter-based air sampling technologies for viable and non-viable bioaerosols. Addresses sampler placement, flow rates, and collection efficiency.

Lesson 1 • Exposure and Needlestick Management

Covers immediate first-aid actions, medical evaluation pathways, and post-exposure prophylaxis for biological exposures. Addresses psychological support needs alongside clinical response.

Lesson 2 • Incident Classification and Notification

Defines incident severity tiers and the notification chains triggered at each level. Establishes the decision framework that drives all subsequent response actions.

Lesson 3 • Post-Incident Investigation and Reporting

Guides root-cause analysis, corrective action planning, and formal incident reporting after a biocontamination event. Produces documentation required by regulatory and institutional standards.

Lesson 4 • Spill Response Procedures

Provides step-by-step spill containment, decontamination, and waste disposal procedures for biological materials. Integrates PPE selection from Chapter 3 and decontamination methods from Chapter 4.

Lesson 1 • Business Continuity and Resilience Planning

Addresses maintaining critical operations during biocontamination events through continuity planning and redundancy. Extends incident response skills from Chapter 6 to organisational resilience.

Lesson 2 • Performance Metrics and Programme Evaluation

Establishes leading and lagging indicators, audit cycles, and management review processes for biosafety programmes. Closes the plan-do-check-act loop for continuous improvement.

Lesson 3 • Hierarchy of Controls Application

Applies elimination, substitution, engineering, administrative, and PPE controls systematically to biocontamination risks. Synthesises containment, decontamination, and PPE knowledge from Chapters 2 through 4.

Lesson 4 • Strategic Communication and Stakeholder Engagement

Develops skills for communicating biocontamination risk to leadership, regulators, and the public with clarity and credibility. Supports organisational trust and regulatory relationship management.
