  • Lesson 2 • Fall Protection Plan Development

    Guides learners through writing a site-specific fall protection plan including monitoring systems and rescue procedures. Integrates all chapter content into a practical deliverable.

  • Lesson 3 • Guardrail and Safety Net Systems

    Covers top rail, mid-rail, and toeboard specifications plus safety net installation and drop distances. Teaches passive protection as the preferred control over personal fall arrest.

  • Lesson 4 • Ladder Safety and Stairways

    Addresses portable and fixed ladder selection, setup angles, and stairway requirements. Reinforces fall prevention through proper access equipment use.

  • Lesson 5 • Scaffolding Safety Essentials

    Reviews supported and suspended scaffold erection, capacity, and access requirements. Connects scaffold safety to fall and falling-object hazard control.

  • Lesson 6 • Fall Hazard Recognition

    Identifies leading-edge, floor opening, roof, and ladder fall hazards using site inspection techniques. Establishes the hazard baseline for all fall protection decisions.

Chapter 4See details

Electrical Safety on Construction Sites

  • Lesson 1 • Overhead and Underground Power Lines

    Establishes minimum approach distances and safe work planning near energised lines. Addresses one of the most lethal electrical hazards in construction.

  • Lesson 2 • Lockout and Tagout Procedures

    Teaches energy isolation steps for electrical, pneumatic, hydraulic, and stored energy sources. Directly prevents contact with hazardous energy during maintenance tasks.

  • Lesson 3 • Temporary Power and GFCI Use

    Covers temporary wiring standards, extension cord ratings, and ground fault circuit interrupter requirements. Addresses the most frequent electrical hazard on active construction sites.

  • Lesson 4 • Electrical Hazard Fundamentals

    Explains current, voltage, resistance, and their effects on the human body. Provides the physics foundation needed to understand all electrical safety controls.

  • Lesson 5 • Electrical PPE and Safe Work Practices

    Covers insulated tools, rubber goods, arc-rated clothing, and safe work practices for energized tasks. Completes the electrical safety control hierarchy with PPE and procedures.

Chapter 5See details

Excavation, Trenching, and Soil Safety

  • Lesson 1 • Protective Systems for Excavations

    Covers sloping, benching, falsework, and trench box specifications for each soil type. Teaches the primary engineering controls that prevent cave-in fatalities.

  • Lesson 2 • Excavation Hazard Controls

    Addresses access and egress, water accumulation, underground utilities, and atmospheric hazards in excavations. Extends protection beyond cave-in to all excavation risks.

  • Lesson 3 • Cave-In Hazard Recognition

    Identifies indicators of unstable excavation walls including tension cracks, water seepage, and surcharge loads. Builds the observational skills that precede protective system selection.
