  1. Define what we mean by human factors, why we use them, provide a brief introduction to the Human Factors Analysis and Coding System (HFACS) and an introduction on how to employ HFACS for operational success.
  2. Define error and violation as causes of accidents.
  3. Distinguish the countermeasures appropriate to prevent error and violation.
  4. Present checklists as a powerful countermeasure for error.
  5. Draw on evidence from healthcare that proves checklists prevent harmful error.
  6. Discuss the characteristics of checklists likely to be most effective in preventing diving accidents.
  7. Broadly describe how choice-making education differs from other instruction and how the PADI system addresses this in recreational diving.
  8. Explain the challenges to good decision making in recreational diving.
  9. Describe a reasonable approach to further reducing recreational diving's very low incidence rate, the evidence supporting the approach and why different dive communities likely need different approaches.
  10. To offer an objective look at how UTD, as a scuba training and certification agency has, since we started, been teaching human factors as part of every student’s curriculum.
  11. Outline the new Diving Incident Reporting System (DIRS) at Divers Alert Network, DAN’s vision and role in injury monitoring.
  12. Understand the US Navy’s approach to safety & risk management.
  13. Recognize potential applications and limitations for improving recreational diver safety.
  14. Understand that human failure is present in all domains.
  15. The best performing organizations are pre-occupied with safety.
  16. Understand barriers to failure are Recognition, Recovery and Resilience.
