Environmental Hygiene Course

Master the science and practice of environmental hygiene — from microbiology and water quality to surface disinfection and waste management. This course gives you the technical knowledge and hands-on frameworks professionals use to prevent disease, meet regulatory standards, and protect public health. Whether you work in facilities, food safety, healthcare, or public health, you'll finish ready to design and manage effective hygiene programmes.

Dedika for businesses

What you will learn:

This course covers all key areas of environmental hygiene: disease transmission and microbiology basics, water and indoor air quality, surface cleaning, and waste management. You’ll learn to select and apply disinfectants, manage Legionella in building water systems, and apply HACCP-based food safety controls. It also addresses hygiene auditing, risk assessment, and performance metrics to run a full programme confidently. Additional modules cover pest control, occupational safety, healthcare infection prevention, digital monitoring tools, and sustainability. By course end you’ll be able to assess risks, write SOPs, lead audits, and communicate hygiene requirements to any team.

  • Lesson 2 • Defining Environmental Hygiene

    Covers the scope, terminology, and boundaries of environmental hygiene as a discipline. Provides the conceptual framework used throughout the course.

  • Lesson 3 • Historical Context and Evolution

    Traces milestones from early sanitation reforms to modern hygiene science. Demonstrates how past outbreaks shaped current standards.

  • Lesson 4 • Regulatory and Standards Overview

    Introduces the types of regulatory frameworks and voluntary standards governing environmental hygiene. Prepares students to navigate compliance requirements.

Chapter 2See details

Microbiology Essentials for Hygiene Professionals

  • Lesson 1 • Environmental Survival of Pathogens

    Examines how temperature, humidity, pH, and surfaces affect pathogen survival. Informs decisions about cleaning frequency and environmental conditions.

  • Lesson 2 • Microbial Categories and Characteristics

    Distinguishes bacteria, viruses, fungi, and protozoa by structure and behaviour. Provides the biological basis for selecting targeted hygiene controls.

  • Lesson 3 • Indicators and Monitoring Organisms

    Introduces indicator organisms used to assess contamination levels in water, air, and surfaces. Connects microbial monitoring to hygiene programme evaluation.

  • Lesson 4 • Antimicrobial Resistance Awareness

    Explains how resistance develops and why it complicates hygiene interventions. Guides responsible selection and rotation of antimicrobial agents.

Chapter 3See details

Water Quality and Hygiene

  • Lesson 1 • Water Quality Testing and Parameters

    Teaches physical, chemical, and microbiological testing methods and acceptable parameter ranges. Enables accurate interpretation of water quality data.

  • Lesson 2 • Water Sources and Contamination Risks

    Identifies surface, groundwater, and distribution system contamination sources. Establishes risk context for water treatment decisions.

  • Lesson 3 • Water Treatment Processes

    Covers coagulation, filtration, and disinfection as sequential treatment steps. Explains how each step reduces specific contaminant categories.

  • Lesson 4 • Legionella and Water System Management

    Addresses Legionella risk in building water systems and control measures. Applies risk assessment to cooling towers, hot water systems, and fixtures.

Chapter 4See details

Air Quality and Ventilation Hygiene

  • Lesson 1 • Air Quality Monitoring and Sampling

    Covers instruments and protocols for measuring airborne contaminants in occupied spaces. Enables data-driven decisions about ventilation adequacy.

  • Lesson 2 • HVAC Maintenance and Hygiene Controls

    Details cleaning, filter replacement, and inspection schedules for HVAC systems. Prevents system-generated contamination and maintains air quality standards.

  • Lesson 3 • Ventilation Systems and Principles

    Explains natural, mechanical, and hybrid ventilation systems and their hygiene implications. Connects airflow design to contaminant dilution and removal.

  • Lesson 4 • Indoor Air Pollutants and Sources

    Catalogues biological, chemical, and particulate indoor air pollutants and their emission sources. Provides the hazard inventory needed for risk assessment.

Chapter 5See details

Surface Cleaning and Disinfection

  • Lesson 1 • Specialised Decontamination Methods

    Covers fogging, UV-C irradiation, and electrostatic spraying as adjunct decontamination technologies. Clarifies appropriate use cases and limitations.

  • Lesson 2 • Cleaning Agents and Chemistry

    Explains detergent types, surfactant action, and pH effects on soil removal. Provides the chemical basis for matching agents to surface and soil types.

  • Lesson 3 • Cleaning and Disinfection Procedures

    Establishes step-by-step procedures for cleaning before disinfection and correct application techniques. Ensures consistent, effective decontamination outcomes.

  • Lesson 4 • Cleaning Programme Design and Scheduling

    Teaches how to build cleaning schedules, assign responsibilities, and document compliance. Translates individual procedures into a managed hygiene programme.

  • Lesson 5 • Disinfectant Selection and Efficacy

    Compares disinfectant classes by spectrum, contact time, and surface compatibility. Guides evidence-based selection for specific hygiene scenarios.

Chapter 6See details

Waste Management and Hygiene

  • Lesson 1 • Wastewater and Liquid Waste Hygiene

    Addresses sewage, greywater, and liquid chemical waste management to protect water sources. Connects wastewater hygiene to broader environmental protection goals.

  • Lesson 2 • Safe Waste Handling and Storage

    Covers container selection, storage area requirements, and handling procedures to minimise exposure. Reduces worker and environmental contamination risk.

  • Lesson 3 • Waste Treatment and Disposal Methods

    Explains incineration, autoclaving, chemical treatment, and landfill options for different waste streams. Matches disposal method to waste category and risk level.

  • Lesson 4 • Waste Classification and Segregation

    Defines general, hazardous, clinical, and sharps waste categories and segregation requirements. Prevents cross-contamination at the point of generation.
