Occupational Safety Engineering Course

Lesson 1 • Safety Culture and Organizational Behavior

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 organizations.

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 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 Labeling

Covers globally harmonized labeling 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 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 characterization 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 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 1 • Thermal Environment and Radiation Hazards

Assesses heat stress, cold stress, and ionizing and non-ionizing radiation risks in industrial settings. Connects physiological thresholds to control measure selection.

Lesson 2 • Occupational Health Surveillance Programs

Designs biological monitoring, medical surveillance, and health screening programs 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 1 • Pressure Systems and Mechanical Integrity

Examines pressure vessel design standards, inspection regimes, and failure modes. Mechanical integrity programs prevent catastrophic loss of containment.

Lesson 2 • Layer of Protection Analysis

Applies layer of protection analysis to quantify risk reduction from independent protection layers. Connects process hazard analysis findings to safety instrumented system design.

Lesson 3 • Process Safety Management Fundamentals

Introduces process safety management elements including process hazard analysis and management of change. Distinguishes process safety from occupational safety in scope and consequence.

Lesson 4 • Emergency Planning for Process Facilities

Develops emergency response plans, evacuation procedures, and community notification protocols for major hazard sites. Integrates on-site and off-site emergency resources.

Lesson 1 • Causal Analysis Methods

Applies cause-and-effect diagrams, the five-whys technique, and barrier analysis to trace causal chains. Multiple methods increase confidence in root cause identification.

Lesson 2 • Scene Preservation and Evidence Collection

Covers immediate response, scene security, physical evidence collection, and witness interviewing. Evidence quality determines the accuracy of root cause findings.

Lesson 3 • Systemic Root Cause Frameworks

Introduces systemic frameworks that identify organizational and management system failures behind incidents. Systemic analysis prevents recurrence more effectively than individual-factor fixes.

Lesson 4 • Incident Investigation Principles

Establishes the purpose, scope, and legal context of workplace incident investigations. Distinguishes blame-free investigation from disciplinary processes to encourage reporting.

Lesson 1 • Continual Improvement and Change Management

Applies nonconformity management, corrective action systems, and management of change to drive SMS improvement. Sustains safety gains through structured review cycles.

Lesson 2 • Safety Policy, Objectives, and Planning

Guides development of safety policy statements, measurable objectives, and operational plans. Aligns safety goals with organizational strategy and resource allocation.

Lesson 3 • Internal Audit and Management Review

Designs audit programs, trains auditors, and structures management review meetings. Audits verify SMS conformance and identify improvement opportunities.

Lesson 4 • Leading and Lagging Performance Indicators

Distinguishes proactive leading indicators from reactive lagging metrics and selects appropriate measures. Balanced indicator sets enable early detection of deteriorating safety performance.
