Reviewing the literature on time on task effects on safety shows contradictory evidence, especially with regard to 12 h shifts. It is argued that this might depend on methodological problems associated with the analysis of accident data, e.g. selectivity of samples, validity of data bases and study designs, especially for analyses at the company level. Analyses of aggregated data seem to indicate an exponential increase of accident risk with time on task beyond the normal working day. This is supported by some recent studies based on data from the Federal Republic of Germany.
回顾关于任务执行时间对安全性影响的文献会发现相互矛盾的证据，尤其是在12小时轮班方面。有人认为，这可能取决于与事故数据分析相关的方法问题，例如样本的选择性、数据库的有效性和研究设计，特别是在公司层面进行分析时。对汇总数据的分析似乎表明，在正常工作日之后，事故风险会随着任务执行时间呈指数级增长。这得到了一些近期基于德意志联邦共和国数据的研究的支持。
