1 Human Factors Analysis and Classification System HFACSA tool to promotea safer fire service
2 Overview Why HFACS? What is HFACS? Using the tool.
3 Human Factors Analysis and Classification System (HFACS) is a general human error framework originally developed and tested within the U.S. military as a tool for investigating and analyzing the human causes of aviation accidents.
4 Student Performance Objective Given an introduction to the Human Factors Analysis and Classification System (HFACS), students/users will apply the tool to various near-miss reports to gain a greater understanding of the role human factors plays in near-misses and mishaps.
5 Opportunities to learn Why Study Near Misses?1TragicOpportunity to learn300Survival StoriesOpportunities to learn1 SeriousAccident15 Major AccidentsFocus on fact that near misses offer 300 more opportunities to improve safety versus one serious accident. Near misses are typically less painful and tragic than serious accidents or fatalities.300 Near Misses15,000 Observed Worker Errors
6 Contributing Factors Self reported. Confirmed by interview. “Human” elements lead list.
7 Error Person Approach System Approach www.firefighternearmiss.com Basic Premise: unsafe acts arise primarily from aberrant mental process such as forgetfulness, inattention, poor motivation, carelessness, negligence, and recklessness.Focuses on the unsafe acts, errors, and procedural violations of people at the sharp end: firefighters, engineers, company officers, paramedics, etc.Counter measures: reduce unwanted variability in human behavior. Methods include poster campaigns that appeal to people’s sense of fear, writing procedure (or adding to existing one), disciplinary measures, threat of litigation, retraining, naming, blaming, and shaming.System ApproachBasic Premise: humans are fallible and errors are to be expected, even in the best organizations.Errors seen as consequences rather than causes, origins in “upstream” systemic factors. These include recurrent error traps in the workplace and the organization processes that give rise to them.Counter measures: change the conditions under which humans work. Central Idea is system defenses. All hazardous technologies posses barriers and safeguards. When an adverse event occurs, the important issue is not who blundered, but how and why the defenses failed.
