🔎 Incident Investigation & Root Cause Analysis

Free incident investigation & RCA training with a completion certificate.

Last updated: June 2026

Learn how to investigate incidents and near-misses to prevent recurrence — not to assign blame. Master reporting and legal notification, the three levels of cause, 5 Whys, fishbone (Ishikawa 6M), timelines and barrier (bow-tie) analysis, the 4 Ps of evidence, witness interviewing, CAPA closed-loop verification and how safety performance is measured with TRIR, LTIFR and leading indicators. 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.

What you'll learn

  • Why we investigate — prevention, not blame
  • Report & legally notify — incidents and near-misses
  • First response & securing the scene
  • Immediate, underlying and root causes
  • Methods: timelines, 5 Whys, fishbone (6M) & bow-tie
  • Evidence (4 Ps) & interviewing witnesses
  • CAPA, hierarchy of controls & measuring (TRIR/LTIFR)

Learning objectives

  • Investigate to prevent recurrence under a just culture — not to blame
  • Report and legally notify all incidents and near-misses (OSHA 29 CFR 1904, RIDDOR)
  • Take the correct first response: make safe, isolate energy and preserve the scene
  • Tell immediate, underlying and root causes apart
  • Apply 5 Whys, fishbone/Ishikawa (6M), timelines and barrier (bow-tie) analysis
  • Gather evidence across the 4 Ps and interview witnesses cognitively, blame-free
  • Build effective CAPA on the hierarchy of controls with verified close-out (ISO 45001 cl.10.2)
  • Calculate and interpret TRIR, LTIFR and pair them with leading indicators
