Biot safety training

Lesson 1 • Ethical Responsibilities in Biosafety

This section examines the ethical duty of researchers and technicians to protect colleagues and the public. It connects personal accountability to organisational biosafety culture.

Lesson 2 • Biological Agents and Their Properties

This topic categorises bacteria, viruses, fungi, parasites, and toxins by transmission and virulence. Understanding agent properties drives appropriate containment decisions.

Lesson 3 • Core Biosafety Terminology

This section defines essential vocabulary used throughout biosafety practice. Precise language enables accurate communication during risk assessments and incident reporting.

Lesson 4 • Regulatory and Oversight Frameworks

This module surveys international and national biosafety oversight bodies and their functional roles. You will identify which authorities govern your work environment.

Lesson 1 • Procedure-Specific Risk Evaluation

This topic applies risk assessment to common laboratory procedures such as centrifugation and pipetting. Procedure-level analysis reveals hidden hazards not captured by agent classification alone.

Lesson 2 • Risk Assessment Principles

This topic introduces the probability-consequence model applied to biological hazards. It establishes the logical structure used in all subsequent assessment activities.

Lesson 3 • Exposure Route Analysis

This topic analyses inhalation, ingestion, percutaneous, and mucous membrane exposure pathways. Identifying likely routes shapes selection of engineering controls and PPE.

Lesson 4 • Agent Risk Group Classification

This topic explains the four-tier risk group system for classifying biological agents by hazard level. Classification directly determines required containment level and work practices.

Lesson 1 • Selecting the Correct Biosafety Level

This topic integrates risk assessment outputs with BSL criteria to make defensible containment decisions. You will practice level selection using realistic case scenarios.

Lesson 2 • Biosafety Level 4 Overview

This topic surveys maximum containment requirements for agents with no available treatment or vaccine. It provides awareness-level knowledge for personnel who may support BSL-4 operations.

Lesson 3 • Biosafety Level 1 Practices

This topic covers basic microbiological practices for work with well-characterised, low-risk agents. It establishes the minimum acceptable standard for any biological laboratory.

Lesson 4 • Biosafety Level 2 Practices and Facilities

This topic details enhanced practices, access controls, and facility features required at BSL-2. You will apply BSL-2 requirements to the most common clinical and research settings.

Lesson 1 • PPE Inspection and Maintenance

This topic covers pre-use inspection criteria, storage requirements, and decontamination of reusable PPE. Defective PPE provides false security and must be identified before use.

Lesson 2 • Respiratory Protection Fundamentals

This topic distinguishes surgical masks, N95 respirators, PAPRs, and supplied-air systems by protection level. You will match respirator type to aerosol hazard and work duration.

Lesson 3 • PPE Programme Management

This topic addresses institutional responsibilities for PPE procurement, training, and recordkeeping. A managed programme ensures consistent protection across all personnel.

Lesson 4 • PPE Selection Principles

This topic links exposure route analysis and agent risk group to specific PPE categories. Correct selection prevents both under-protection and unnecessary discomfort.

Lesson 1 • BSC Certification and Maintenance

This topic explains annual certification requirements, HEPA filter integrity testing, and routine maintenance. Uncertified cabinets must not be used for biological work.

Lesson 2 • BSC Types and Protection Profiles

This topic compares Class I, II (A2, B1, B2), and III cabinets by airflow design and protection offered. Selecting the wrong cabinet type can expose workers or contaminate products.

Lesson 3 • Correct BSC Operating Techniques

This topic details pre-use preparation, work zone organisation, and movement discipline inside the cabinet. Technique errors disrupt protective airflow and compromise containment.

Lesson 4 • Common BSC Use Errors

This topic identifies frequent mistakes such as blocking the front grille and working too fast. Recognising errors allows you to self-correct before contamination occurs.

Lesson 1 • Chemical Disinfectants

This topic surveys bleach, alcohols, quaternary ammonium compounds, and glutaraldehyde by spectrum and use. Correct disinfectant selection depends on agent type and surface material.

Lesson 2 • Infectious Waste Classification

This topic categorises sharps, liquid waste, solid biological waste, and animal carcasses by disposal pathway. Misclassification leads to regulatory violations and worker exposure.

Lesson 3 • Autoclave Sterilisation

This topic covers steam sterilisation cycles, load configuration, and biological indicator validation. Autoclaving is the primary method for rendering infectious materials safe for disposal.

Lesson 4 • Waste Segregation and Disposal

This topic establishes colour-coding, labelling, storage, and transport requirements for infectious waste. Proper segregation at the point of generation prevents downstream contamination.

Lesson 1 • Standard Microbiological Practices

This topic reinforces the foundational work habits that prevent exposure across all biosafety levels. These practices form the behavioural backbone of any biosafety programme.

Lesson 2 • Immunisation and Medical Surveillance

This topic identifies vaccines recommended for laboratory workers and the role of baseline serum banking. Medical surveillance detects early infection and supports post-exposure management.

Lesson 3 • Behavioural Risk Factors and Human Error

This topic examines complacency, fatigue, and normalisation of deviance as drivers of laboratory accidents. Behavioural interventions complement engineering controls in reducing risk.

Lesson 4 • Safe Sharps and Needlestick Prevention

This topic addresses engineering controls, safe work practices, and needle-free alternatives to prevent percutaneous injuries. Sharps injuries remain the most frequent laboratory exposure event.

Lesson 1 • Exposure Incident Management

This topic covers immediate first aid, notification chains, and medical evaluation after a biological exposure. Timely response improves outcomes and satisfies reporting obligations.

Lesson 2 • Containment Failure and Evacuation

This topic addresses scenarios involving HVAC failure, BSC malfunction, or uncontrolled aerosol release. You will execute evacuation and shelter-in-place decisions under pressure.

Lesson 3 • Incident Reporting and Investigation

This topic establishes internal and external reporting requirements and root cause investigation methods. Thorough investigation prevents recurrence and fulfils regulatory obligations.

Lesson 4 • Emergency Preparedness Planning

This topic guides development of facility-specific biological emergency response plans and drills. Practised plans reduce chaos and decision errors during actual emergencies.
