Master the full scope of occupational safety engineering — from hazard identification and risk assessment to process safety and safety management systems. This course gives you the technical knowledge and practical tools to protect workers, meet regulatory requirements, and drive a stronger safety culture in any industrial environment.
What you will learn:
You will build a solid foundation in safety engineering principles, regulatory frameworks, and hazard control strategies. You will learn to conduct risk assessments using both qualitative and quantitative methods, design engineering controls, and develop administrative programmes like lockout tagout and permit to work systems. The course also covers industrial hygiene, process safety management, fire and electrical safety, and incident investigation. You will gain skills in human factors, behavioural safety, and data analytics to support proactive decision-making. By the end, you will be equipped to lead safety programmes, communicate with diverse stakeholders, and advance your professional career in occupational safety engineering.

8 Chapters • 40 LessonsDuration between 4 and 360 hours (you decide)
Chapter 1HideHide detailsSee detailsFoundations of Occupational Safety Engineering
Foundations of Occupational Safety Engineering
Lesson 1 • Safety Culture and Organisational Behaviour
Examines how leadership, communication, and worker attitudes shape safety outcomes. Establishes the human dimension that underpins all technical interventions.
Lesson 2 • Roles and Responsibilities of Safety Engineers
Maps professional duties, ethical obligations, and interdisciplinary collaboration. Clarifies accountability structures within organisations.
Lesson 3 • History and Evolution of Workplace Safety
Traces industrial accidents that shaped modern safety practice and regulatory frameworks. Provides historical context for understanding why current standards exist.
Lesson 4 • Core Safety Concepts and Terminology
Defines hazard, risk, exposure, and control as foundational vocabulary. Precise terminology enables consistent communication across all subsequent topics.
Lesson 5 • Regulatory Frameworks and Compliance Basics
Introduces the structure of occupational safety regulation and employer duty-of-care principles. Connects legal requirements to engineering decision-making.
Chapter 2HideHide detailsSee detailsHazard Identification and Classification
Hazard Identification and Classification
Lesson 1 • Hazard Identification Techniques
Covers walkthroughs, checklists, job safety analysis, and structured interviews. Each technique is matched to specific workplace contexts and hazard types.
Lesson 2 • Hazard Documentation and Registers
Establishes standards for recording identified hazards in registers and tracking systems. Accurate documentation supports risk assessment and audit processes.
Lesson 3 • Hazard Communication and Labelling
Covers globally harmonised labelling systems, safety data sheets, and workplace signage. Ensures workers receive accurate hazard information at the point of exposure.
Lesson 4 • Energy-Based Hazard Analysis
Applies energy transfer theory to identify sources of harm in mechanical, electrical, and thermal systems. Provides a unifying model for diverse hazard types.
Lesson 5 • Types of Workplace Hazards
Categorises physical, chemical, biological, ergonomic, and psychosocial hazard classes. Classification drives appropriate identification and control strategies.
Chapter 3HideHide detailsSee detailsRisk Assessment Principles and Methods
Risk Assessment Principles and Methods
Lesson 1 • Risk Assessment Fundamentals
Defines risk as a function of likelihood and consequence and introduces the risk assessment cycle. Anchors all subsequent assessment methods in a common framework.
Lesson 2 • Exposure Assessment and Dose-Response
Quantifies worker exposure to chemical, physical, and biological agents against health benchmarks. Links exposure data to risk characterisation decisions.
Lesson 3 • Risk Communication and Reporting
Translates technical risk findings into clear reports for management and workers. Effective communication drives timely risk-reduction decisions.
Lesson 4 • Qualitative Risk Assessment Methods
Applies risk matrices, what-if analysis, and preliminary hazard analysis to rank risks. Suitable for early-stage projects and resource-limited environments.
Lesson 5 • Semi-Quantitative and Quantitative Methods
Introduces fault tree analysis, event tree analysis, and failure mode and effects analysis. Provides numerical risk estimates for complex or high-consequence systems.
Chapter 4HideHide detailsSee detailsHazard Control and the Hierarchy of Controls
Hazard Control and the Hierarchy of Controls
Lesson 1 • Engineering Controls Design
Covers guarding, ventilation, isolation, and interlocks as primary engineering solutions. Connects control design to hazard type and exposure pathway.
Lesson 2 • Administrative Controls and Safe Work Procedures
Develops permit-to-work systems, lockout/tagout procedures, and job rotation policies. Administrative controls supplement engineering measures to reduce residual risk.
Lesson 3 • Hierarchy of Controls Framework
Explains elimination, substitution, engineering controls, administrative controls, and PPE in priority order. Establishes the decision logic for all control selection.
Lesson 4 • Control Effectiveness Verification
Establishes methods for testing, monitoring, and auditing implemented controls. Verification closes the loop between control design and actual risk reduction.
Lesson 5 • Personal Protective Equipment Selection
Guides selection, fit-testing, maintenance, and training for respiratory, hearing, and body protection. PPE effectiveness depends on correct specification and consistent use.
Chapter 5HideHide detailsSee detailsIndustrial Hygiene and Health Hazard Management
Industrial Hygiene and Health Hazard Management
Lesson 1 • Thermal Environment and Radiation Hazards
Assesses heat stress, cold stress, and ionising and non-ionising radiation risks in industrial settings. Connects physiological thresholds to control measure selection.
Lesson 2 • Occupational Health Surveillance Programmes
Designs biological monitoring, medical surveillance, and health screening programmes for exposed workers. Surveillance data validates exposure controls and detects early health effects.
Lesson 3 • Ergonomics and Musculoskeletal Disorder Prevention
Applies ergonomic assessment tools to identify manual handling, posture, and repetition risks. Ergonomic interventions reduce musculoskeletal disorder incidence and lost time.
Lesson 4 • Occupational Noise and Vibration Control
Quantifies noise exposure, hearing loss risk, and vibration-induced disorders using measurement standards. Guides engineering and administrative noise reduction strategies.
Lesson 5 • Chemical Hazard Recognition and Toxicology
Covers routes of entry, toxicological mechanisms, and health effects of common industrial chemicals. Toxicology knowledge underpins accurate exposure limit selection.
Chapter 6HideHide detailsSee detailsProcess Safety and Major Hazard Management
Process Safety and Major Hazard Management
Lesson 1 • Pressure Systems and Mechanical Integrity
Examines pressure vessel design standards, inspection regimes, and failure modes. Mechanical integrity programmes prevent catastrophic loss of containment.
