ABSTRACT To examine the causes of chainsaw-related injuries and fatalities in tree felling work in Japan, we determined trends in fatal accidents occurring during chainsaw tree felling, as well as factors influencing injuries related to this work. We further explored the extent to which such accidents might be prevented by education. Our analysis was based on 2000–2014 data released by various Japanese government organizations. At the prefecture scale, there was a strong correlation between timber production volume and the number of fatal accidents during chainsaw felling. Accidents occurred most frequently on Fridays, and fatal accidents occurred most frequently around 9:00 a.m. and 3:00 p.m. Among the 14 factors associated with tree felling accidents, correct setting of the notch and hinge might have prevented 33.6% of all factors. We conclude that increased education to improve notch and hinge setting would be effective in chainsaw felling accident prevention.

日本电锯砍伐相关伤害的相关因素

摘要 为了调查日本砍伐树木工作中电锯相关伤害和死亡的原因，我们确定了电锯砍伐树木期间发生的致命事故的趋势，以及影响与这项工作相关的伤害的因素。我们进一步探讨了教育可以在多大程度上预防此类事故。我们的分析基于日本各政府组织发布的 2000-2014 年数据。在县范围内，木材产量与链锯砍伐过程中的致命事故数量之间存在很强的相关性。周五事故发生频率最高，上午9:00和下午3:00左右发生致命事故最频繁。在与砍伐事故相关的14个因素中，正确设置缺口和铰链可能阻止了所有因素的33.6%。
