A near miss is an unplanned event that did not result in injury, illness, or damage but had the potential to. It signals a weakness in the system that could lead to more serious consequences if not corrected. Near misses can include unsafe conditions, behaviors, minor incidents that could have been worse, and events where safety barriers were crossed but injury did not occur. While human error often plays a role, the focus of improvement should be on fixing faulty processes and systems that allow or compound the risk. Tracking near misses can help identify the greatest risks and opportunities to improve safety practices before a serious injury occurs according to the Incident Ratio Model.
