The purpose of this investigation was to enhance our understanding of the effects the current British Columbia Wildfire Service (BCWS) firefighting schedule have on the development of fatigue and sleep deprivation. This was a cohort study that objectively and subjectively measured sleep quantity, sleep quality, and fatigue throughout a 17-day British Columbia wildland firefighting deployment. Wildland firefighters (n = 30) conducted daily testing of sleep and fatigue measures during 14 days of activity on the fire line and three days immediately post deployment during their three-day rest period, for a total of 17 days of data collection. Sleep was assessed using wrist-worn actigraphy (ActiGraph LLC, Pensacola, FL) and subjective sleep questionnaires. Fatigue was assessed using subjective fatigue questionnaires and cognitive performance through the psychomotor vigilance test. Total sleep time was less on fire days (M = 6.6 h ± 49.2 min) compared to non-fire days (M = 6.8 h ± 92.2 min). Participants performed poorer on cognitive performance tests, (p = 0.288), and reported being significantly sleepier, (p = 0.038), toward the end of their 17-day deployment compared to day 1. Participants continued to report high levels of sleepiness, fatigue, and poor quality of sleep on their rest days compared to their fire line days. Working 14 consecutive days was associated with increased levels of objective fatigue and suboptimal sleep in wildland firefighters. Wildland firefighters reported significantly higher levels of fatigue and decreased alertness with increasing days on deployment and these levels did not improve following a three-day rest period.

这项调查的目的是增进我们对当前不列颠哥伦比亚省野火局（BCWS）消防计划对疲劳和睡眠剥夺发展的影响的了解。这是一项队列研究，客观地和主观地测量了不列颠哥伦比亚省野外消防部署17天期间的睡眠量，睡眠质量和疲劳程度。野外消防员（n = 30）每天在消防线上进行14天的活动时进行睡眠和疲劳措施的日常测试，并在三天的休息期内进行部署后立即进行三天的测试，总共收集了17天的数据。使用手腕上的活动记录仪（ActiGraph LLC，彭萨科拉，佛罗里达州）和主观睡眠问卷评估睡眠。使用主观疲劳问卷和通过心理运动警惕性测试的认知表现来评估疲劳。火灾天的总睡眠时间更少（M  = 6.6小时±49.2分钟），相比于非火天（M  = 6.8小时±92.2分钟）。与第1天相比，在17天部署结束时，参与者的认知能力测试表现较差（p = 0.288），并且报告的睡眠明显较弱（p = 0.038）。参与者继续报告高度的困倦，疲劳，与休息日相比，他们在休息日的睡眠质量较差。连续工作14天与旷野消防员的客观疲劳水平和不理想的睡眠水平增加相关。野地消防员报告说，随着部署天数的增加，疲劳程度明显提高，警觉性降低，并且在三天的休息时间后，这些水平并没有改善。
