Electrical Safety Course

Lesson 1 • Workplace Electrical Risk Factors

Examines environmental and behavioural conditions that elevate electrical risk. Connects site conditions to injury probability for practical risk awareness.

Lesson 2 • Types of Electrical Hazards

Defines shock, arc flash, arc blast, and electrical fire as distinct hazard categories. Enables accurate hazard classification before any control measure is selected.

Lesson 3 • How Electricity Causes Harm

Covers current pathways through the body, voltage thresholds, and tissue damage mechanisms. Grounds all subsequent hazard recognition in physiological reality.

Lesson 1 • Reading Electrical Diagrams

Teaches single-line diagrams, schematic symbols, and panel schedules. Accurate diagram reading is prerequisite to safe isolation and verification procedures.

Lesson 2 • Circuit Components and Their Functions

Identifies conductors, insulators, switches, fuses, breakers, and transformers by function. Enables correct component recognition during inspection and isolation tasks.

Lesson 3 • AC and DC Power Fundamentals

Contrasts alternating and direct current characteristics, waveforms, and common applications. Provides the electrical theory base needed to interpret equipment nameplates and ratings.

Lesson 4 • Grounding and Bonding Principles

Explains system earthing, equipment earthing, and bonding as distinct but related safety functions. Establishes the theory behind fault current paths covered in later chapters.

Lesson 1 • Arc Flash Hazard Analysis

Introduces incident energy calculations, flash protection boundaries, and equipment labelling requirements. Directly supports PPE selection and approach distance decisions.

Lesson 2 • Hierarchy of Controls Application

Maps elimination, substitution, engineering, administrative, and PPE controls to electrical hazards. Guides selection of the most effective control at each risk level.

Lesson 3 • Hazard Identification Methods

Applies visual inspection, job safety analysis, and incident data review to surface electrical hazards. Structured identification prevents overlooked risks during pre-task planning.

Lesson 4 • Documenting and Communicating Risk

Covers risk assessment report formats, permit attachments, and crew briefing techniques. Ensures hazard information reaches every worker before the job starts.

Lesson 1 • Tagout-Only Situations and Limitations

Defines when tagout is permitted, its reduced protection level, and required compensating measures. Prevents over-reliance on tags where physical locks are feasible.

Lesson 2 • Energy Control Programme Requirements

Outlines written programme elements, authorised employee roles, and annual audit requirements. Establishes the administrative foundation before any physical isolation step.

Lesson 3 • Identifying All Energy Sources

Locates electrical, stored, pneumatic, hydraulic, and gravitational energy sources on equipment. Complete energy source identification prevents residual-energy injuries.

Lesson 4 • Step-by-Step Lockout Sequence

Executes the notify, shut down, isolate, lock, release, and verify sequence in correct order. Procedural discipline at each step eliminates accidental re-energisation.

Lesson 1 • PPE Care, Storage, and Records

Establishes cleaning, storage, and documentation practices that preserve PPE integrity between uses. Proper records support compliance audits and replacement scheduling.

Lesson 2 • Shock Protection PPE

Covers insulating gloves, sleeves, blankets, and mats rated by voltage class. Correct class selection prevents dielectric failure during energised contact.

Lesson 3 • PPE Inspection and Testing

Performs pre-use visual inspection and periodic electrical testing of insulating PPE. Defective PPE removed from service before it causes a fatality.

Lesson 4 • Face and Head Protection

Selects arc flash face shields, arc-rated hoods, hard hats, and hearing protection for energised work. Integrates head and face protection into a complete PPE ensemble.

Lesson 1 • Test Before Touch Verification

Uses voltage testers and multimeters to confirm absence of voltage before contact. Verification with calibrated instruments prevents shock from assumed de-energised conductors.

Lesson 2 • Energised Work Justification

Establishes the business-case and safety criteria required before any energised work is approved. Reduces unnecessary energised exposure by demanding documented justification.

Lesson 3 • Insulated Tools and Equipment

Selects and inspects insulated hand tools, hot sticks, and test equipment rated for the task voltage. Tool integrity is the last physical barrier between the worker and live conductors.

Lesson 4 • Two-Person Rule and Standby

Implements buddy system and standby observer requirements for high-hazard energised tasks. A trained observer enables immediate emergency response if an incident occurs.

Lesson 1 • CPR and AED Application

Performs hands-only and full CPR cycles and operates an AED on a victim of electrical cardiac arrest. Immediate CPR and defibrillation are the primary survival factors after electrocution.

Lesson 2 • Recognising Electrical Injuries

Identifies internal burns, cardiac arrhythmia, respiratory arrest, and blast trauma in shock victims. Early recognition determines the correct first-aid sequence and urgency.

Lesson 3 • Burn and Trauma First Aid

Applies cooling, covering, and immobilisation techniques for arc flash burns and blast injuries. Correct burn care limits tissue damage and infection risk before medical transfer.

Lesson 4 • Scene Safety and Victim Release

Establishes rescuer safety priorities and safe methods to separate a victim from live conductors. Prevents the rescuer from becoming a second victim during electrical emergencies.

Lesson 1 • Inspection and Audit Processes

Conducts scheduled and unannounced safety inspections using standardised checklists. Regular audits surface non-conformances before they result in injuries.

Lesson 2 • Continuous Improvement and Review

Applies plan-do-check-act cycles to update procedures, training, and controls based on audit and incident findings. Continuous review keeps the programme aligned with changing equipment and regulations.

Lesson 3 • Training Programme Design

Builds task-based training curricula for qualified and unqualified electrical workers. Competency-based training ensures workers can perform tasks safely, not just recite rules.

Lesson 4 • Incident Trend Analysis

Analyses near-miss, first-aid, and recordable incident data to identify systemic failure patterns. Trend data drives proactive programme improvements rather than reactive fixes.
