1 Human Factors Analysis and Classification System HFACS A tool to promote a safer fire service

2 Overview Why HFACS? What is HFACS? Using the tool.

3 (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. Human Factors Analysis and Classification System

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 Why Study Near Misses? 1 Serious Accident 15 Major Accidents 300 Near Misses 15,000 Observed Worker Errors 1Tragic Opportunity to learn Opportunity to learn 300 Survival Stories Opportunities to learn

6 Contributing Factors Self reported. Confirmed by interview. Human elements lead list.

7 Error Person Approach 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 peoples sense of fear, writing procedure (or adding to existing one), disciplinary measures, threat of litigation, retraining, naming, blaming, and shaming. System Approach Basic 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.

8 To error is human... How It Is Now... You are highly trained and If you did as trained, you would not make mistakes so You werent careful enough so You should be PUNISHED! How It Should Be... Humans make mistakes so Lets also explore why the system allowed, or failed to accommodate your mistake and Lets IMPROVE THE SYSTEM! You are human and

10 HFACS Focuses on four areas of human performance Acts Preconditions to Acts Supervision Organizational Influences

11 Acts or Error Lack of skill Lack of education/training Poor decision making misperception Violation Willful disregard for rules & regulations

12 Preconditions to Acts Assesses condition of person or people involved Focused or distracted Hurried Physically ill or unfit Wrong person for job CRM used Readiness

13 Supervision Adequate or inadequate Failure to correct Planned inappropriate ops Effect of freelancing

14 Organizational Influences Most difficult to assess Need to read between the lines Resources Departmental climate SOPs (or lack of)

15 Near Miss Latent Conditions Active Conditions Failed or Absent Defenses Organizational Influences Unsafe Supervision Preconditions for Unsafe Acts Unsafe Acts Modified from Shappell & Wiegmann, JSSC 1997 Reasons Swiss Cheese
