Participants are required to purchase and bring their copy of the CSA Z462-18 Standard to the course as well as a calculator.

After Participating in this course, you will be able to:

  • Understand principles of Electrical Safety per OSHA 29CFR 1910(S), CSA Z462 2018
  • Apply the above methodology with Safe Work Practices for Industrial Electrical work
  • Be aware of the requirements for a Qualified Electrical Worker
  • Use knowledge gained for PPE selection, use of barriers, barricades, boundaries and signage
  • Be able to perform risk assessments

This course covers principles of Electrical Safety to reduce incidents of Shock and Arc Flash. The contents of CSA Z462 and its American counterpart NFPA 70E are a result of cumulative studies on incidents documented by OSHA since 1970 involving injuries and fatalities due to Electrical Energy.

What this course does not cover is the practical component of this standard required for Electrical Workers involving field demonstration of LV/MV Safe Work practices. What this course also does not cover is any build of Electrical systems or Electrical Work Standards /Practices. They are part of Canadian Electrical Code.

Course Outline:

  • History, evolution and chronology of the standard CSA Z462
  • Arc Flash and shock theory and boundaries
  • Boundary distance calculation, tables, interpreting Arc Flash labels
  • Risk assessment
  • Review of JHA/JSA and job planning forms
  • PPE study
  • Setting up a safe work zone, safe work practices
  • Medium voltage systems (1kV-69kV) considerations
  • Flexible cords and portable tools
  • Definition, requirements of a qualified electrical worker

Who Should Attend:
Electrical Engineers • Managers who supervise Electricians or Operators of Electrical Equipment • Plant Supervisors, Operations Personnel and Foremen • Human Resource and Safety Professionals for Manufacturing, Processing Facilities • Instrumentation, Controls and Manufacturing Engineers • Owners of Plants, Facilities with risk of Electrical Incidents

Special Features:
Participants are required to purchase and bring their copy of the CSA Z462-18 Standard to the course.
