Incident Investigation & Root Cause Analysis
The Incident Investigation & Root Cause Analysis course teaches participants how to investigate workplace incidents, identify root causes, and implement corrective actions. It equips professionals with the skills to prevent future incidents, improve safety systems, and enhance overall workplace safety.

What is the Incident Investigation & Root Cause Analysis?
The Incident Investigation and Root Cause Analysis course from the American Institute of Safety Professionals provides comprehensive training on the systematic investigation of workplace incidents to determine not just what happened (the immediate cause) but why it happened (the root causes and systemic failures) and what must change to prevent recurrence. Most incident investigations stop too soon: they identify the worker’s error or the equipment failure and implement a corrective action directed at that immediate cause. Effective investigations go deeper: they identify the management system failures, organisational factors, and cultural conditions that allowed the immediate cause to exist. An investigation that finds only “worker error” has failed because it has not identified what the system failed to provide. The curriculum covers investigation planning and team formation, evidence collection and preservation (physical evidence, photographs, documents, data), witness interviewing techniques (open-ended questions, timeline reconstruction, avoiding leading questions, managing reluctant witnesses), root cause analysis methodologies (5-Why analysis, Fault Tree Analysis, Systematic Cause Analysis Technique (SCAT), TapRooT awareness, Fishbone/Ishikawa), the distinction between immediate causes, contributing factors, and root causes, recommendation development (specific, measurable, assigned, resourced, time-bound), corrective action implementation and verification, investigation report writing, OSHA investigation requirements (§1904.39 reporting, PSM §1910.119(m) investigation), and investigation programme management (which incidents to investigate, investigation quality, trending, and organisational learning). All training is delivered 100 percent online through Microsoft Teams and the American Institute of Safety Professionals LMS. Upon completion, graduates receive a certificate, wallet card, and transcript, employer-verifiable at amiosp.com/student-verifications.
