Free electrical safety & arc flash awareness training (NFPA 70E / OSHA 1910.333) with a completion certificate.

Last updated: June 2026

Recognise shock, arc-flash and arc-blast hazards, respect the shock and arc-flash approach boundaries, de-energise with lockout/tagout, verify the absence of voltage, and select arc-rated PPE by incident energy — to NFPA 70E and OSHA 1910.331–335. It maps to NFPA 70E / OSHA 1910.333. The course is organized into 7 modules, ending with a final exam (pass mark 80%). It is free awareness-level training designed for anyone who needs a practical, working understanding of the topic.

  • Arc-rated PPE by category
  • Hierarchy of controls for electrical risk
  • Qualified vs unqualified persons & safe work practices
  • When something goes wrong

Learning objectives

  • Distinguish the shock, arc-flash and arc-blast hazards and the injuries each causes
  • Explain the limited and restricted shock-approach boundaries and the arc-flash boundary
  • Apply the hierarchy of risk controls and place de-energising (lockout/tagout) before energised work
  • Perform the full LOTO sequence and verify the absence of voltage before touching
  • State when an energized electrical work permit is required and what an arc-flash label must show
  • Select arc-rated PPE by incident energy (cal/cm²) and the correct NFPA 70E PPE category
  • Respond correctly and safely to an electric shock or arc-flash burn emergency
