8 Chapters • 36 LessonsDuration between 4 and 360 hours (you decide)

Chapter 1See details

Foundations of Accident Prevention

  • Lesson 1 • Human Factors in Accident Events

    Examines how perception, fatigue, and decision-making contribute to accidents. Links human limitations directly to preventable failure points.

  • Lesson 2 • Environmental and Organizational Factors

    Identifies workplace conditions and organizational culture as accident contributors. Connects systemic factors to individual behavior outcomes.

  • Lesson 3 • The Cost of Accidents

    Quantifies direct and indirect costs of accidents to individuals and organizations. Motivates proactive prevention by framing financial and human consequences.

  • Lesson 4 • Understanding Accidents and Their Causes

    Defines accidents, near-misses, and incidents using causation models. Builds the conceptual baseline for every risk-reduction technique in the course.

Chapter 2See details

Hazard Identification and Risk Assessment

  • Lesson 1 • Conducting Formal Risk Assessments

    Guides students through a complete written risk assessment process. Produces documentation that satisfies regulatory and organizational requirements.

  • Lesson 2 • Dynamic and Ongoing Hazard Monitoring

    Addresses hazards that emerge during operations rather than pre-task planning. Builds habits for continuous vigilance throughout a work shift.

  • Lesson 3 • Risk Evaluation and Prioritization

    Applies likelihood-severity matrices to rank identified hazards. Enables teams to allocate limited resources to the highest-priority risks first.

  • Lesson 4 • Hazard Recognition Techniques

    Teaches structured methods for identifying physical, chemical, and behavioral hazards. Provides practical tools applicable across diverse work environments.

Chapter 3See details

Hierarchy of Controls Application

  • Lesson 1 • Engineering Controls Design

    Explains physical barriers, guards, and ventilation systems that isolate hazards. Connects engineering solutions to sustained risk reduction without relying on behavior.

  • Lesson 2 • Administrative Controls and Safe Work Practices

    Addresses procedures, schedules, and training as behavioral risk reducers. Clarifies their limitations compared to higher-order controls.

  • Lesson 3 • Elimination and Substitution Controls

    Covers the two highest-order controls that remove or replace hazards entirely. Establishes why these options must always be evaluated before lower-level controls.

  • Lesson 4 • Personal Protective Equipment Selection

    Covers PPE as the last line of defense when higher controls are insufficient. Teaches proper selection, fit-testing, and maintenance requirements.

  • Lesson 5 • Combining Controls for Layered Defense

    Demonstrates how multiple control levels work together to reduce residual risk. Applies the Swiss cheese model from Chapter 1 to real control combinations.

Chapter 4See details

Situational Awareness and Perception Skills

  • Lesson 1 • Team Situational Awareness

    Extends individual awareness to shared team perception and communication. Builds collective vigilance that compensates for individual blind spots.

  • Lesson 2 • Principles of Situational Awareness

    Introduces Endsley's three-level model of perception, comprehension, and projection. Provides the cognitive framework underlying all awareness-based prevention skills.

  • Lesson 3 • Managing Distractions and Tunnel Vision

    Addresses cognitive traps that narrow attention and cause missed hazards. Provides practical techniques to maintain broad awareness during complex tasks.

  • Lesson 4 • Recognizing Pre-Accident Indicators

    Trains students to identify subtle warning signs before a hazard escalates. Directly reduces the gap between hazard onset and corrective response.

Chapter 5See details

Safe Decision-Making Under Pressure

  • Lesson 1 • Decision-Making Models for Safety

    Compares analytical and naturalistic decision models relevant to safety contexts. Establishes when each model is most appropriate given time and information constraints.

  • Lesson 2 • Go/No-Go Decision Frameworks

    Provides structured criteria for deciding whether to proceed, pause, or stop a task. Reduces ambiguity in high-consequence decisions by applying clear thresholds.

  • Lesson 3 • Stress Inoculation and Pressure Management

    Prepares students to maintain decision quality under stress through rehearsal and regulation techniques. Bridges cognitive theory to physical performance under real conditions.

  • Lesson 4 • Cognitive Biases That Cause Accidents

    Identifies confirmation bias, normalization of deviance, and plan continuation errors. Teaches countermeasures that interrupt biased reasoning before it leads to harm.

  • Lesson 5 • After-Action Review for Decision Learning

    Uses structured debriefs to extract lessons from both good and poor decisions. Converts experience into transferable decision-making improvements.

Chapter 6See details

Emergency Response and Accident Mitigation

  • Lesson 1 • Emergency Response Planning Essentials

    Covers the components of an effective emergency response plan and activation triggers. Ensures students understand their role before an emergency occurs.

  • Lesson 2 • Incident Reporting and Documentation

    Establishes accurate, timely reporting as a critical post-accident obligation. Links quality documentation to effective investigation and future prevention.

  • Lesson 3 • Controlling Secondary Hazards

    Addresses fire, chemical release, and structural hazards that follow an initial accident. Teaches containment actions that prevent escalation to larger-scale emergencies.

  • Lesson 4 • First Response Actions at an Accident Scene

    Teaches the immediate priority sequence: scene safety, alert, and initial aid. Prevents responders from becoming secondary victims while stabilizing the situation.

Chapter 7See details

Accident Investigation and Root Cause Analysis

    Defines the purpose of investigation as learning, not blame, and establishes team composition. Sets the cultural and procedural foundation for objective fact-finding.

  • Lesson 2 • Corrective Action Development and Tracking

    Translates root cause findings into specific, measurable corrective actions. Establishes ownership and follow-up systems to ensure actions are completed.

  • Lesson 3 • Root Cause Analysis Methods

    Applies fault tree analysis, fishbone diagrams, and the five-whys technique. Moves investigation beyond immediate causes to systemic organizational failures.

  • Lesson 4 • Evidence Collection and Analysis

    Covers physical, documentary, and testimonial evidence gathering techniques. Ensures a complete evidence base before any causal conclusions are drawn.

  • Lesson 5 • Sharing Lessons Across the Organization

    Converts investigation findings into organization-wide learning opportunities. Prevents similar accidents in areas not directly involved in the original incident.

Chapter 8See details
