All incidents, whether a near miss or an actual injury-related event, should be investigated. Near miss reporting and investigation allow you to identify and control hazards before they cause a more serious incident. Accident/incident investigations are a tool for uncovering hazards that either were missed earlier or have managed to slip out of the controls planned for them. It is useful only when done with the aim of discovering every contributing factor to the accident/incident to “foolproof” the condition and/or activity and prevent future occurrences. In other words, your objective is to identify root causes, not to primarily set blame.
