ABSTRACT

Fatigue that is related to the amount and quality of sleep obtained can impair human performance in ways that can lead to accidents. As many transportation industries operate around the clock, fatigue and its effects cannot be eliminated completely; instead, they must be managed. A first step is to document the prevalence and role of fatigue in accidents that occur. The Transportation Safety Board of Canada (TSB) routinely investigates such transportation industry incidents to determine if fatigue was present, if it played a role, and if there were practices in place to effectively manage it and associated risks. Herein, we summarize and describe the TSB’s fatigue investigation methodology in the hopes that investigators of other organizations and domains will find the concepts applicable to their operational context.

摘要

与获得的睡眠量和质量有关的疲劳会以可能导致事故的方式损害人类的表现。由于许多运输行业全天候工作，疲劳及其影响无法完全消除。相反，必须对其进行管理。第一步是记录疲劳发生率和发生事故的作用。加拿大运输安全委员会（TSB）定期调查此类运输行业事件，以确定是否存在疲劳，疲劳是否起作用以及是否存在有效管理疲劳和相关风险的实践。在此，我们总结并描述了TSB的疲劳调查方法，希望其他组织和领域的调查人员可以找到适用于其运营环境的概念。
