背景过去几十年的许多工业灾难，包括三哩岛、切尔诺贝利、博帕尔、埃克森巴尔德斯和爱沙尼亚费里，都发生在凌晨。后续调查的结论是，它们至少部分归因于人类疲劳和/或错误。长时间工作对健康和安全的潜在影响是一个主要问题，导致了各种工作时间regulation.Methods的伤害和“事故”（事件）的风险与功能的工作时间表从已发表的流行病学研究汇总使用添加剂模型，形成一个“风险指数”。“的估计风险的事件为各种标准的工作时间表提出使用建议model.Results的伤害或事故的估计风险与任何给定的每周工作时间的数量有很大的不同，这取决于如何工作时间组成。的风险取决于长度和类型的转变，以及频率的休息breaks.Conclusions，我们的结论是，把一个限制与特定的工作时间表的风险可能比设置每天，每周或每月的工作时间的规定，在保持工作场所的安全在可接受的范围内更有效。
Background Many of the industrial disasters of the last few decades, including Three Mile island, Chernobyl, Bhopal, Exxon Valdez, and the Estoniaferry, have occurred in the early hours of the morning. Follow-up investigations concluded that they were at least partially attributable to human fatigue and/or error. The potential impact of long work hours on health and safety is a major concern that has resulted in various work hour regulations.Methods The risk of injuries and "accidents" (incidents) associated with features of work schedules from published epidemiological studies are pooled using an additive model to form a "Risk Index." The estimated risks of an incident for various standard work schedules are presented using the proposed model.Results The estimated risk of an injury or accident associated with any given number of weekly work hours varies substantially depending on how work hours are comprised. The risk depends on the length and type of shift, as well as the frequency of rest breaks.Conclusions We conclude that placing a limit on the risk associated with a particular work schedule is likely more effective than setting daily, weekly or monthly work hour regulations in keeping workplace safety within acceptable limits.
