NTSB Training Center 


Investigating Human Fatigue Factors


This course will provide participants with information and guidance to evaluate the role human fatigue plays in an accident sequence, including whether it was causal or contributing. It will cover fatigue-related issues at the individual, medical, operational and environmental levels, and discuss how these issues affect human performance, alertness and safety. The course will also examine the types of information that should be collected during an investigation. Case studies and hands-on exercises will demonstrate the concepts discussed in the classroom.

  • Individual factors – age, sleep need versus sleep obtained, external stressors, circadian disruption, diet and exercise, and alcohol and tobacco use.
  • Medical factors – sleep disorders, and mental and physical health disorders.
  • Operational factors – work/shift schedules, time zone changes, rest opportunities, and automation.
  • Environmental factors – noise, vibration, lighting, and temperature.
  • Effects of fatigue – how individual, medical, environmental and operational factors affect human performance, alertness and safety.
  • Collecting and analyzing fatigue factors – how to gather, interpret and analyze fatigue information, including relevant questions to ask operators, organization representatives, family members, and others.
  • Assessing fatigue factors – how to assess the significance of fatigue factors in an accident investigation and determine its role in the accident sequence.
  • Practical application – class exercises will include interviewing for fatigue, and interpretation and analysis of fatigue related performance factors in an accident investigation

Performance Results

Upon completion of this course the participant will be able to:

  • Employ interview techniques and relevant questions to determine how fatigue may have contributed to an accident sequence.
  • Use the knowledge and skills acquired in the course to build a foundation for the inclusion or exclusion of fatigue as a factor in an accident investigation.
  • Determine if fatigue played a role in an accident, and if it did, whether it was contributory or causal.
