Electrical Safety Technician Course

Lesson 1 • Arc Flash and Arc Blast Basics

Introduces arc flash physics, plasma temperatures, and blast pressure. Provides the conceptual basis for all arc flash protection covered later.

Lesson 2 • Electrical Shock Hazards

Explains physiological effects of current through the human body. Connects current magnitude and path to injury severity and fatality thresholds.

Lesson 3 • Regulatory and Standards Framework

Surveys the hierarchy of electrical safety regulations, consensus standards, and employer duties. Establishes the compliance mindset required throughout the course.

Lesson 4 • Electrical Fire Hazards

Identifies overload, short circuit, and poor connection as fire causes. Links heat generation to insulation failure and ignition of surrounding materials.

Lesson 1 • Risk Assessment Methodology

Introduces likelihood-times-consequence risk matrices and job hazard analysis. Provides a repeatable process for evaluating any electrical task.

Lesson 2 • Hazard Recognition Techniques

Trains visual and instrument-based methods for spotting electrical hazards. Reinforces the shock and arc flash concepts from Chapter 1 in field conditions.

Lesson 3 • Energised vs. De-Energised Work Decisions

Establishes the hierarchy favouring de-energised work and the justification process for energised exceptions. Directly supports lockout/tagout decisions in Chapter 3.

Lesson 4 • Voltage Level Classifications

Defines low, medium, and high voltage boundaries and their associated hazard profiles. Guides selection of controls and PPE based on system voltage.

Lesson 1 • Identifying and Isolating Energy Sources

Teaches location and isolation of all electrical energy sources on a machine or system. Builds on voltage classification knowledge to address each source type.

Lesson 2 • Energy Control Programme Fundamentals

Covers the written programme requirements, scope, and roles within a LOTO system. Establishes the administrative foundation before hands-on procedure steps.

Lesson 3 • Applying Lockout and Tagout Devices

Demonstrates correct application of locks, tags, hasps, and lockout stations. Covers device selection, labelling, and the one-lock-per-worker rule.

Lesson 4 • Restoring Equipment to Service

Details the safe sequence for removing LOTO devices and re-energising equipment. Addresses shift changes, unexpected re-energisation, and lock removal authority.

Lesson 1 • Protective Earthing for De-Energised Lines

Teaches application of temporary protective earths on de-energised conductors. Addresses induced voltage and accidental re-energisation scenarios.

Lesson 2 • Bonding Principles and Requirements

Covers equipotential bonding to eliminate voltage differences between conductive parts. Addresses bonding in industrial, commercial, and temporary power contexts.

Lesson 3 • Earthing System Testing and Verification

Introduces fall-of-potential and clamp-on methods for measuring earth resistance. Provides acceptance criteria and troubleshooting steps for failed tests.

Lesson 4 • Earth Fault Protection Devices

Covers GFCI, AFCI, and equipment earth fault protection operation and testing. Connects device function to the shock and fire hazards identified in Chapter 1.

Lesson 1 • Insulating Gloves and Sleeves

Covers voltage class ratings, inspection procedures, and air testing for rubber insulating gloves and sleeves. Addresses the most critical shock protection item.

Lesson 2 • Arc-Rated Clothing and Face Protection

Explains arc thermal performance value ratings, garment layering, and face shield selection. Covers prohibited materials and proper coverage requirements.

Lesson 3 • PPE Inspection, Care, and Recordkeeping

Establishes inspection schedules, cleaning methods, and storage requirements for all electrical PPE. Introduces the documentation needed to demonstrate compliance.

Lesson 4 • Insulating Tools and Equipment

Covers voltage-rated hand tools, insulated ladders, and rubber insulating matting. Extends PPE concepts to the work environment and tool interface.

Lesson 1 • Temporary Wiring and Extension Cords

Establishes safe use, routing, and protection requirements for temporary power. Addresses the high incident rate associated with improper temporary wiring.

Lesson 2 • Approach Boundaries and Safe Distances

Defines limited, restricted, and prohibited approach boundaries for shock protection. Translates boundary values into physical positioning during live-panel work.

Lesson 3 • Electrical Panel and Switchgear Work

Addresses safe procedures for opening, inspecting, and working inside panels and switchgear. Covers arc flash risk escalation when enclosures are opened.

Lesson 4 • Working on Energised Conductors

Covers one-hand technique, insulated tool use, and body positioning for energised work. Applies PPE and boundary knowledge to real task execution.

Lesson 1 • Arc Flash Burn Treatment

Covers immediate care for arc flash thermal burns, eye injuries, and blast trauma. Distinguishes arc flash burns from conventional thermal burns in severity.

Lesson 2 • Electrical Incident Scene Management

Covers safe approach to an electrical incident scene without becoming a second victim. Applies de-energisation and LOTO knowledge to emergency response.

Lesson 3 • Electrical Shock First Aid

Details assessment and treatment of shock victims including hidden internal injuries. Addresses the delayed cardiac arrest risk unique to electrical shock.

Lesson 4 • Incident Investigation and Reporting

Introduces root cause analysis methods and mandatory reporting obligations after electrical incidents. Connects findings to corrective actions that prevent recurrence.

Lesson 1 • Electrical Safety Audits and Inspections

Covers audit planning, checklist development, and field observation techniques. Provides the tools to measure programme effectiveness and identify gaps.

Lesson 2 • Programme Structure and Written Plans

Defines the required elements of a written electrical safety programme and management accountability. Integrates all procedural elements covered in previous chapters.

Lesson 3 • Contractor and Visitor Safety Management

Addresses host-employer duties when contractors perform electrical work on site. Covers pre-qualification, orientation, and permit coordination with outside workers.

Lesson 4 • Qualified Worker Training Requirements

Establishes training content, frequency, and documentation standards for qualified electrical workers. Addresses initial qualification, task-specific training, and requalification.
