Course content

8 Chapters • 38 LessonsDuration between 4 and 360 hours (you decide)

Chapter 1See details

Foundations of Working at Heights

  • Lesson 1 • Defining Work at Heights

    Clarifies what constitutes work at heights and why it demands specialized controls. Anchors all subsequent chapters in a shared hazard vocabulary.

  • Lesson 2 • Fall Statistics and Incident Analysis

    Presents industry fatality and injury data to contextualize risk severity. Teaches workers to extract lessons from real incident reports.

  • Lesson 3 • Regulatory and Duty-of-Care Framework

    Outlines the legal duties of employers, supervisors, and workers under occupational health and safety regulations. Connects compliance obligations to practical site decisions.

  • Lesson 4 • Hierarchy of Controls for Heights

    Introduces the elimination-to-PPE control hierarchy as applied to fall hazards. Provides the decision-making model used throughout the course.

Chapter 2See details

Hazard Identification and Risk Assessment

  • Lesson 1 • Safe Work Method Statements

    Guides workers through drafting and reviewing safe work method statements for height tasks. Ensures risk assessment outputs are translated into actionable field instructions.

  • Lesson 2 • Site Inspection and Pre-Task Checks

    Covers structured walkthroughs and pre-task inspection checklists for elevated work areas. Reinforces the hierarchy of controls by linking findings to corrective actions.

  • Lesson 3 • Dynamic Risk Assessment in the Field

    Trains workers to reassess risk continuously as conditions change during a task. Builds adaptive decision-making skills that complement formal pre-task assessments.

  • Lesson 4 • Risk Assessment Methodology

    Teaches likelihood-versus-consequence scoring and risk matrix use for height tasks. Connects assessment outputs directly to control selection decisions.

  • Lesson 5 • Types of Height Hazards

    Categorizes physical, environmental, and task-related hazards encountered at elevation. Builds the hazard recognition vocabulary needed for formal assessments.

Chapter 3See details

Fall Prevention: Collective Controls

  • Lesson 1 • Covers and Hole Protection

    Details marking, load rating, and securing methods for floor and roof opening covers. Prevents falls through openings, a leading cause of fatal incidents.

  • Lesson 2 • Safety Nets and Debris Nets

    Explains installation geometry, drop distance, and energy absorption requirements for safety nets. Distinguishes personnel nets from debris nets and their respective applications.

  • Lesson 3 • Guardrail Systems

    Covers load requirements, component specifications, and installation standards for guardrail systems. Establishes guardrails as the preferred engineering control before PPE is considered.

  • Lesson 4 • Warning Lines and Controlled Access Zones

    Defines the conditions under which warning lines and controlled access zones are permissible alternatives. Teaches proper setup dimensions and monitoring requirements.

Chapter 4See details

Personal Fall Arrest Systems

  • Lesson 1 • Harness Fitting and Donning Procedures

    Provides step-by-step fitting and adjustment procedures to ensure harness effectiveness during a fall. Incorrect fit is a leading cause of harness-related injury.

  • Lesson 2 • Inspection, Maintenance, and Retirement

    Establishes pre-use inspection criteria and retirement triggers for all fall arrest components. Ensures equipment integrity is verified before every use.

  • Lesson 3 • Anchor Point Selection and Strength

    Covers minimum anchor strength requirements and methods for identifying suitable structural anchors. Prevents system failure at the most critical connection point.

  • Lesson 4 • Fall Clearance Calculations

    Teaches the arithmetic for determining total fall clearance distance before a worker reaches an obstruction. Ensures workers never use fall arrest where insufficient clearance exists.

  • Lesson 5 • Components of a Fall Arrest System

    Identifies and explains the function of harnesses, lanyards, connectors, and anchor points. Provides the component knowledge required for correct system assembly.

Chapter 5See details

Access Equipment: Ladders and Scaffolding

  • Lesson 1 • Scaffold Erection and Inspection

    Details the sequence for erecting, modifying, and dismantling scaffolding safely. Teaches the competent-person inspection criteria required before worker access.

  • Lesson 2 • Ladder Types and Selection Criteria

    Compares step, extension, and fixed ladder types against task requirements and load ratings. Correct selection prevents overloading and misuse failures.

  • Lesson 3 • Safe Ladder Setup and Use

    Covers angle ratios, securing methods, and three-point contact rules for portable ladders. Directly reduces the most common ladder-related fall mechanism.

  • Lesson 4 • Scaffold Types and Components

    Identifies tube-and-coupler, system, and suspended scaffold types and their structural components. Provides the vocabulary needed for scaffold inspection and erection tasks.

  • Lesson 5 • Working Platform Standards

    Specifies decking, guardrail, and toe board requirements for scaffold working platforms. Ensures platforms meet load and fall prevention standards before use.

Chapter 6See details

Elevated Work Platforms and Mobile Equipment

  • Lesson 1 • Fall Protection Inside the Platform

    Clarifies harness and lanyard requirements specific to boom lifts and the rationale for their use. Addresses the common misconception that guardrails alone are sufficient in boom lifts.

  • Lesson 2 • Emergency Lowering and Rescue

    Trains operators in manual lowering procedures and ground-level rescue activation. Ensures workers can respond when a platform fails or an operator becomes incapacitated.

  • Lesson 3 • Types of Elevated Work Platforms

    Distinguishes scissor lifts, boom lifts, vertical mast lifts, and vehicle-mounted platforms by capability and limitation. Correct type selection prevents task-related incidents.

  • Lesson 4 • Ground and Environmental Hazard Management

    Addresses ground bearing capacity, slope limits, overhead obstructions, and wind speed restrictions. Environmental factors are a leading cause of elevated work platform tip-overs.

  • Lesson 5 • Pre-Operation Inspection Procedures

    Covers manufacturer checklist use, fluid levels, controls, and structural integrity checks before each shift. Identifies defects before they cause in-service failures.

Chapter 7See details

Rope Access and Restraint Systems

  • Lesson 1 • Rope Access Rescue Procedures

    Introduces assisted and self-rescue techniques specific to rope access situations. Rescue planning must be completed before any rope access work begins.

  • Lesson 2 • Basic Rope Access Techniques

    Covers controlled descent, ascent, and lateral movement on rope access systems. Builds foundational technique before advanced maneuvering is introduced.

  • Lesson 3 • Rope Access System Components

    Identifies working lines, safety lines, descenders, ascenders, and anchor configurations used in rope access. Component knowledge underpins correct rigging and inspection.

  • Lesson 4 • Rope and Equipment Inspection

    Establishes inspection criteria for ropes, harnesses, and hardware used in rope access. Rope degradation is often invisible, making systematic inspection critical.

  • Lesson 5 • Fall Restraint Versus Fall Arrest

    Clarifies the fundamental difference between preventing a worker from reaching an edge and arresting a fall after it begins. Correct system selection is the first safety decision.

Chapter 8See details

Rescue Planning and Post-Incident Response

  • Lesson 1 • Incident Investigation and Reporting

    Teaches root-cause analysis techniques and mandatory reporting obligations following a height incident. Accurate investigation prevents recurrence and fulfills legal duties.

  • Lesson 2 • Rescue Methods and Equipment

    Compares self-rescue, assisted rescue, and emergency services rescue for different site scenarios. Equipment selection must match the rescue method and site constraints.

  • Lesson 3 • Suspension Trauma and First Aid

    Explains the physiological danger of prolonged harness suspension and immediate first aid priorities. Suspension trauma can be fatal within minutes, making rapid rescue essential.

  • Lesson 4 • Rescue Planning Requirements

    Defines the regulatory requirement to have a rescue plan before any fall arrest system is used. Covers the elements that make a plan actionable rather than theoretical.

  • Lesson 5 • Post-Incident Review and Improvement

    Guides teams through structured post-incident reviews to update risk assessments and safe work methods. Closes the safety management loop established in Chapter 2.
