1 Human Factors Analysis and Classification System (HFACS) Saving Lives Through Experiences SharedHuman Factors Analysis and Classification System (HFACS)A tool to promotea saferfire service
2 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.
3 Overview Why HFACS? What is HFACS? Using the tool. Why - Most mishaps and near misses are the result of human error at several levels.What – A tool developed, tested and used by the U.S. Navy to investigate mishaps. Applying the tool to near-miss reports will have a positive effect on reducing worker injuries and job related fatalities.Using – The tool is easy to apply after an introduction and background reading.Montgomery County Fire & Rescue (MD)
4 Opportunities to learn Why Study Near Misses?1TragicOpportunity to learn1 SeriousAccident300Survival StoriesOpportunities to learn15 Major Accidents300 Near MissesFocus 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.15,000 Observed Worker ErrorsH. W. Heinrich, 1930
5 Contributing Factors Self reported. Confirmed by interview. “Human” elements lead list.Findings from 2006 & 2007 have human factors (situational awareness, human error, decision making and communication) leading contributing factors’ list for near miss reports.
6 ErrorPerson approachBasic premise: unsafe acts arise primarily from aberrant mental processes 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.Countermeasures: reduce unwanted variability in human behavior. Methods include poster campaigns that appeal to people's sense of fear, writing procedure (or adding to existing ones), 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 organizational processes that give rise to them.Countermeasures: change the conditions under which humans work. Central idea is system defenses. All hazardous technologies possess barriers and safeguards. When an adverse event occurs, the important issue is not who blundered, but how and why the defenses failed.Reason advocates the System Approach, recognizing that accidents are the result of a chain of error and the Person Approach suppresses communication and admission of error.Reason, James, British Journal of Medicine
7 To err is human . . . How It Is Now . . . How It Should Be . . . You are highly trainedYou are humanandandHumans make mistakesIf you did as trained, you would not make mistakessosoLet’s also explore why the system allowed, or failed to accommodate your mistakeYou weren’t careful enoughPunishment for errors results in suppressed reporting of minor mishaps which has been proven to contribute to major incidents. The human factors approach recognizes that humans make mistakes and that those mistakes are usually the culminating effect of multiple factors in the chain of command.soandYou should be PUNISHED!Let’s IMPROVE THE SYSTEM!
8 Reason’s “Swiss Cheese” Ill-defined SOP’sLabor IssuesLow MoraleOrg. InfluencesUnsafe SupervisionTask AllocationFailure to CorrectWillful DisregardPreconditionsUnsafe ActsFatigueComplacencyLoss of Situational AwarenessReason states that when holes line up, disaster occurs. The holes represent situations and conditions that allow errors to turn into tragedies. Reason further states that the accident or incident is a function of omissions or actions at all four areas of human performance.Crew Actions

10 Acts or Error Violation Willful disregard for rules & regulations Lack of skillLack of education/trainingPoor decision makingmisperceptionViolationWillfuldisregard forrules®ulationsorAsk class for examples of each to ensure they understand the concept of what happens in the Unsafe Acts area.
