Fatigue is lethargy and seen as unpleasant experience that occurs from physical labour or mental exertion. Fatigue can be either physical or mental. This paper examines the role of physical fatigue and mental fatigue in the relationship between physical isolation variables (social isolation and loneliness) and safety behaviour (safety compliance and safety participation). A cross-sectional study with data were collected by means of a questionnaire among oil and gas workers (foreign employees working at a remote oil and gas field site located in Kuwait), during a 3-month period (from October 2018 to December 2018). Regression analyses (bivariate and hierarchical), carried out on 387 responses, were employed to test the hypothesized model relating physical isolation variables, fatigue levels, and safety behaviour. The results provide support for the role of mental fatigue in mediating the relationship between loneliness and both types of safety behaviour (compliance and participation). Results indicate that mental fatigue is associated with feeling lonely and has negative effect on safety behaviour, which indicated a greater risk of injury incident rates. The study findings should facilitate the improvement of employee safe behaviour through monitoring workers’ fatigue levels. Moreover, they may enable prompt intervention and help to contribute to the development of recommendations that broaden our understanding of the effects of isolation and remote work in the context of workplace safety. The implications of these results for physical isolation, fatigue and/or safety behaviour interventions in the industry are discussed.

疲劳是嗜睡，被视为由于体力劳动或脑力消耗而产生的不愉快体验。疲劳可以是身体上的，也可以是精神上的。本文考察了身体疲劳和精神疲劳在身体隔离变量（社会隔离和孤独感）与安全行为（安全遵守和安全参与）之间的关系中的作用。通过对石油和天然气工人（在位于科威特的偏远油气田现场工作的外国雇员）进行问卷调查，在 3 个月期间（从 2018 年 10 月至 2018 年 12 月）收集数据的横断面研究. 对 387 个响应进行的回归分析（双变量和分层）被用来测试与物理隔离变量、疲劳水平和安全行为相关的假设模型。结果支持精神疲劳在调节孤独感与两种类型的安全行为（遵守和参与）之间的关系中的作用。结果表明，精神疲劳与孤独感有关，并对安全行为产生负面影响，这表明受伤事故率的风险更大。研究结果应通过监测员工的疲劳程度来促进员工安全行为的改善。此外，它们可以促进及时干预并有助于制定建议，从而扩大我们对工作场所安全背景下隔离和远程工作影响的理解。讨论了这些结果对行业中物理隔离、疲劳和/或安全行为干预的影响。
