10 Maybe we just need to Focus … And we won’t make errors

11 Exercise 3 – Count the Passes

12 Misinterpretation/Sensory conflicts Inaccurate mental picture/Pattern matching In-attentional Blindness Limited attention resources – We can concentrate on, at most, 2-3 things simultaneously Limited working memory – Most people can reliably remember 5-7 items at a time How Errors Occur

14 Willful Violation: Deliberate, intentional acts to evade a known policy or procedure requirement for personal advantage usually adopted for fun, comfort, expedience, or convenience What an Error is NOT!

15 Unwanted act or behavior overlooked or encouraged to achieve goal You get what you accept! Condoned Behavior



18 Task Demands Time Pressure Irrecoverable acts Simultaneous multiple tasks Monotonous actions Error Likely Conditions Individual Capabilities Unfamiliar with task Illness / fatigue Unsafe attitude toward task Work Environment Distractions / Interruptions Workarounds Changes Personality conflicts Human Nature Stress Habit patterns Complacency Assumptions

19 Error Likely Conditions

20 Error Likely Conditions

21 Physical or administrative measures put in place to prevent accidents or mitigates their consequences. – PPE – Safety Rules – Policies, Procedures, and Guidelines – Training – Tools and Equipment – Oversight Error Prevention Tools Error Defenses/Barriers

22 Defense-in-Depth Reason, J. BMJ 2000;320:768-770 Communication Training Tools & Equipment PPE What other “pieces of cheese” can you think of? Event!

23 Job Hazard Assessment/Pre-Job Brief Self Checking (STAR) Peer Checking 3 Legged communication Situational Awareness Questioning Attitude Stop When Unsure Error Prevention Tools

24 Identify existing and potential job site hazards Identify how hazards will be addressed Discussion with all job participants to ensure mutual understanding and to ensure all questions and concerns are addressed Pre-Job Brief shall cover at least the following subjects: – hazards associated with the job – work procedures involved – special precautions – energy source controls – personal protective equipment requirements – questions Job Hazard Assessment / Pre-Job Brief

25 S TOP – Is my attention focused on the task? T HINK – What action am I about to perform? A CT – Am I performing correctly? R EVIEW – Did I get the expected results? S.T.A.R – Self Checking

26 A “second set of eyes” to detect and prevent errors. To be used when performing critical work prior to taking action. Peer Checking

27 Used during the execution of critical steps to formalize communication. Repeat-back should be used when speaking with Operating entities. Ensures mutual understanding Three-Legged Communication h?v=AHx7xYNdha0

28 Continual assessment of surroundings Recognize changes in job scope/conditions Recognizing changes in behavior Situational Awareness See the Big Picture v=H2QALNgmL2s

29 Stop, look, and listen – proactively search for uncertain or unfamiliar situation Gather information – ask questions … don’t assume Questioning Attitude Look for indicator words such as “I think”, “it looks like”, “it should be”, “it normally is”, “I guess”, …

30 If you have a feeling that something is not right – STOP! If you are not sure of the course of action of the outcome of your actions – STOP! STOP When Unsure
