The sudden release of an energy source during installation, maintenance or repair work is still one of the main causes of serious work accidents. Therefore, energy control (whether electrical, thermal, gravitational, hydraulic or other) is a key element to performing work safely.

This lockout e-learning training deals with fundamental principles, tools and methods used to isolate equipment from these energies, and to lock access to these sources to avoid any uncontrolled use.

Target Audience

Any worker, mechanic or operator who performs or participates in work on fixed or mobile machinery.



  • Define lockout/tagou
  • Describe why hazardous energy is a problem
  • Differentiate between an “authorized” and “affected” employee
  • List and describe the six steps of an effective energy control program
  • Describe lockout hardware
  • Describe the training requirements for lockout tagout
  • Describe the role of the primary authorized employee during a group lockout
  • Describe the procedure for restarting affected equipment
