Electrical Lockout/Tagout Training

This Electrical Lockout/Tagout Training course gives workers and safety professionals the practical knowledge to control hazardous energy and prevent serious injuries on the job. From identifying every energy source to executing group lockout procedures, you will build the skills that keep crews safe. Get compliant, get confident, and get it done right.

Dedika for businesses

What you will learn:

You will learn how to identify every type of hazardous energy on industrial equipment, including electrical, stored mechanical, hydraulic, and thermal sources. The course walks you through the complete six-step lockout/tagout procedure, hardware selection, and verification testing before any work begins. You will also cover group lockout coordination, shift-change handoffs, and contractor accountability. Arc flash hazard analysis and PPE selection are included so you can work safely near energized equipment when lockout is not possible. Finally, you will develop skills to write machine-specific procedures, conduct annual program audits, and manage training records that hold up to regulatory inspection.

Course content

8 Chapters • 35 LessonsDuration between 4 and 360 hours (you decide)

Chapter 1See details

Foundations of Electrical Hazard Safety

  • Lesson 1 • Scope of Lockout/Tagout Programmes

    Defines which tasks and equipment require lockout/tagout controls. Learners distinguish covered servicing activities from normal production operations.

  • Lesson 2 • Roles and Responsibilities on the Job

    Identifies authorised, affected, and other employees in an energy control programme. Clarifies accountability at each role to prevent unauthorised re-energisation.

  • Lesson 3 • Regulatory Framework for Energy Control

    Introduces the regulatory basis for lockout/tagout programmes without citing specific codes. Learners understand employer and worker obligations under energy control standards.

  • Lesson 4 • Understanding Electrical Energy Hazards

    Covers voltage, current, and arc flash as workplace dangers. Connects physical properties of electricity to real injury and fatality risks.

Chapter 2See details

Types of Hazardous Energy Sources

  • Lesson 1 • Stored Mechanical and Hydraulic Energy

    Addresses springs, gravity loads, and pressurised hydraulic systems adjacent to electrical work. Learners recognise when mechanical energy must be controlled alongside electrical isolation.

  • Lesson 2 • Thermal and Chemical Energy Hazards

    Identifies heat stored in conductors, capacitors, and chemical processes near electrical systems. Learners apply cool-down and neutralisation steps before work begins.

  • Lesson 3 • Electrical Energy Sources and Forms

    Covers AC and DC circuits, capacitors, and battery systems as energy sources. Learners map energy entry points on common industrial equipment.

  • Lesson 4 • Energy Source Identification Techniques

    Teaches systematic methods for locating all energy sources on a piece of equipment. Learners use equipment drawings, nameplates, and physical inspection to build energy inventories.

Chapter 3See details

Lockout/Tagout Hardware and Devices

  • Lesson 1 • Lockout Devices and Their Applications

    Covers padlocks, hasps, circuit breaker lockouts, and valve lockouts. Learners select the correct device for each isolation point type.

  • Lesson 2 • Device Inspection and Maintenance

    Establishes criteria for inspecting lockout hardware before each use. Learners remove defective devices from service and document replacements.

  • Lesson 3 • Specialised Isolation Hardware

    Introduces blanking flanges, electrical plug covers, and pneumatic line caps for complex systems. Learners identify specialty devices needed for non-standard isolation points.

  • Lesson 4 • Tagout Devices and Their Limitations

    Explains when tags are used instead of locks and their inherent limitations. Learners apply additional safety measures required when physical lockout is not feasible.

Chapter 4See details

The Six-Step Lockout/Tagout Procedure

  • Lesson 1 • Stored Energy Release and Verification

    Covers bleeding, blocking, grounding, and restraining residual energy after isolation. Learners verify zero energy state using appropriate test instruments.

  • Lesson 2 • Preparation and Hazard Assessment

    Covers pre-job review of energy sources, equipment drawings, and written procedures. Learners gather all required hardware and notify affected employees before starting.

  • Lesson 3 • Applying Lockout and Tagout Devices

    Demonstrates correct placement of locks and tags on each isolation point. Learners apply personal locks and complete tag information before proceeding.

  • Lesson 4 • Equipment Shutdown and Isolation

    Teaches proper shutdown sequencing and operation of energy-isolating devices. Learners distinguish between energy-isolating devices and energy-control devices.

  • Lesson 5 • Verification Testing Before Work Begins

    Establishes the try-out test and instrument-based verification as mandatory final steps. Learners confirm de-energisation before any body part contacts the equipment.

Chapter 5See details

Restoring Equipment to Service

  • Lesson 1 • Notifying Affected Employees Before Restart

    Establishes communication requirements before re-energising equipment. Learners notify all affected employees and confirm the area is clear before applying power.

  • Lesson 2 • Pre-Release Inspection and Cleanup

    Covers inspection of the work area for tools, materials, and personnel before lock removal. Learners verify that all work is complete and the equipment is ready for service.

  • Lesson 3 • Re-Energisation and System Verification

    Covers the controlled application of energy and functional testing after restart. Learners confirm normal equipment operation and report any anomalies immediately.

  • Lesson 4 • Lock and Tag Removal Sequence

    Teaches the rule that only the worker who applied a lock may remove it. Learners follow the correct removal order and update documentation upon removal.

Chapter 6See details

Complex and Group Lockout Scenarios

  • Lesson 1 • Group Lockout Procedures and Hasps

    Explains how multiple workers each apply personal locks to a shared hasp. Learners assign a group coordinator and track individual lock accountability.

  • Lesson 2 • Temporary Removal of Lockout Devices

    Defines the limited conditions under which a lock may be temporarily removed for testing. Learners re-establish full lockout protection immediately after the test is complete.

  • Lesson 3 • Shift-Change and Contractor Handoffs

    Addresses continuity of protection when workers change shifts or contractors enter the work area. Learners apply transfer procedures that maintain uninterrupted lockout protection.

  • Lesson 4 • Emergency and Abandoned Lock Removal

    Establishes the authorised procedure for removing a lock when the worker is unavailable. Learners follow management-authorised steps and document the emergency removal.

  • Lesson 5 • Complex Multi-Energy Equipment

    Covers equipment with multiple electrical feeds, stored energy sources, and interconnected systems. Learners develop and follow written procedures for each unique complex machine.

Chapter 7See details

    Establishes documentation standards for training records, audits, and procedure libraries. Learners organise records to support regulatory inspections and internal reviews.

  • Lesson 3 • Continuous Improvement and Programme Metrics

    Introduces key performance indicators for measuring lockout/tagout programme effectiveness. Learners use incident rates, audit scores, and near-miss data to drive programme improvements.

  • Lesson 4 • Competency Assessment Methods

    Covers written tests, practical demonstrations, and field observations as competency tools. Learners design assessments that verify real-world lockout skill, not just knowledge recall.

  • Lesson 5 • Initial Training Requirements by Role

    Defines training content and depth required for authorised, affected, and other employees. Learners align training scope to each role's actual job tasks and hazard exposure.
