Chapter 3See details

Hazard Controls and Prevention Strategies

  • Lesson 1 • Engineering Controls in Practice

    Details ventilation, guarding, isolation, and containment systems as primary control measures. Connects design principles to real workplace applications.

  • Lesson 2 • Personal Protective Equipment Programmes

    Addresses PPE selection, fit testing, maintenance, and training requirements. Establishes PPE as the last line of defence within a layered control strategy.

  • Lesson 3 • Hierarchy of Controls Framework

    Explains elimination, substitution, engineering, administrative, and PPE controls in order of effectiveness. Anchors all control selection decisions made in this chapter.

  • Lesson 4 • Control Effectiveness Verification

    Teaches methods for monitoring whether controls perform as intended over time. Links verification activities to continuous improvement and audit processes.

  • Lesson 5 • Administrative Controls and Safe Work Procedures

    Covers permit-to-work systems, lockout/tagout, and written safe work procedures. Provides tools for managing residual risk after engineering controls are applied.

Chapter 4See details

Occupational Health and Industrial Hygiene

  • Lesson 1 • Chemical Exposure Assessment

    Covers air sampling strategies, analytical methods, and interpretation of chemical exposure data. Directly supports control selection and regulatory compliance decisions.

  • Lesson 2 • Physical Agents and Health Effects

    Examines noise, vibration, radiation, and thermal stress as occupational health hazards. Connects physical agent exposure to measurable health outcomes and control needs.

  • Lesson 3 • Industrial Hygiene Principles and Practice

    Defines anticipation, recognition, evaluation, and control as the industrial hygiene framework. Establishes the professional methodology applied throughout this chapter.

  • Lesson 4 • Ergonomics and Musculoskeletal Health

    Addresses ergonomic risk factors, workstation design, and musculoskeletal disorder prevention. Integrates ergonomic principles with the hazard control strategies from Chapter 3.

  • Lesson 5 • Occupational Health Surveillance Programmes

    Covers medical surveillance design, biological monitoring, and fitness-for-duty assessments. Ensures health data informs ongoing exposure control and programme improvement.

Chapter 5See details

Environmental Protection and Pollution Control

  • Lesson 1 • Pollution Prevention and Sustainability

    Introduces source reduction, green chemistry, and life-cycle thinking as prevention strategies. Advances environmental management beyond compliance toward proactive sustainability.

  • Lesson 2 • Hazardous Waste Identification and Management

    Teaches waste characterisation, classification, storage, and disposal requirements. Ensures proper handling from generation through final disposal.

  • Lesson 3 • Water Quality and Wastewater Management

    Addresses stormwater, process wastewater, and groundwater protection requirements. Links water management practices to permit compliance and environmental risk reduction.

  • Lesson 4 • Air Quality Management and Emissions Control

    Covers emission sources, air quality standards, and control technology selection. Connects emission inventories to permit compliance and community health protection.

  • Lesson 5 • Environmental Regulatory Compliance Fundamentals

    Introduces permit systems, environmental impact assessment, and reporting obligations. Provides the compliance foundation for all environmental management activities.
