Human error

<p>Human error is an action that has been done but that was "not intended by the actor; not desired by a set of rules or an external observer; or that led the task or system outside its acceptable limits". Human error has been cited as a primary cause and contributing factor in disasters and accidents in industries as diverse as <a href="/facts/Nuclear_and_radiation_accidents_and_incidents/Sqcvbk0e">nuclear power</a> (e.g., the <a href="/facts/Three_Mile_Island_accident/TWPp30Iq">Three Mile Island accident</a>), <a href="/facts/Pilot_error/XJe3jQ8b">aviation</a>, <a href="/facts/List_of_spaceflight-related_accidents_and_incidents/yoI0cEQd">space exploration</a> (e.g., the <a href="/facts/Space_Shuttle_Challenger_disaster/HMBh3T7Q">Space Shuttle Challenger disaster</a> and <a href="/facts/Space_Shuttle_Columbia_disaster/gsTyKuLM">Space Shuttle Columbia disaster</a>), and <a href="/facts/Medical_error/1RyM0bdK">medicine</a>. Prevention of human error is generally seen as a major contributor to <a href="/facts/Data_integrity/g3XGbKIH">reliability</a> and <a href="/facts/Safety/jyH5HLSg">safety</a> of (complex) systems. Human error is one of the many contributing causes of <a href="/facts/Risk/tbBEDA0V">risk</a> events.
