Slips, trips, and falls (STFs) pose a significant financial burden to employers and account for over 33% of the total nonfatal workers' compensation cost in the United States. Previous analyses documenting the burden of STF incidents in the mining industry have focused on occupational fatalities or STFs during equipment ingress, egress. There is limited information on the burden of nonfatal STF incidents in the mining industry and most of it is outdated. Hence, to increase awareness and highlight the importance of STFs in the mining industry, this analysis documents the burden associated with nonfatal STF incidents at surface stone, sand, and gravel (SSG) mines from 2008 through 2017. In this time frame, nonfatal STF incidents occurred at a rate of 62 per 10,000 full-time equivalent (FTE) employees per year. Pits had a higher prevalence of injuries, but plants had a higher incidence rate. In addition, nonfatal STF incidents at surface SSG mines led to approximately 23,800 total days lost per year with an estimated cost to the mining industry of $17.5 million per year. Assessed violations that are not related to reported injuries but are related to STF hazards identified during Mine Safety and Health Administration (MSHA) inspections cost the mining industry approximately $3 million per year from 2013 through 2017. Based on the data analyzed in this study, falls to the lower level pose a higher burden in terms of cost; however, falls to the same level have a higher number of incidents and incidence rate.
滑倒、绊倒和跌倒(STF)给雇主带来了巨大的经济负担,在美国非致命工伤赔偿总成本中占比超过33%。此前记录采矿业STF事件负担的分析主要集中在职业死亡或设备进出期间的STF。关于采矿业非致命STF事件负担的信息有限,且大部分已过时。因此,为了提高认识并突出STF在采矿业中的重要性,本分析记录了2008年至2017年期间地表石材、砂石矿(SSG)非致命STF事件的负担。在此时间范围内,非致命STF事件的发生率为每年每10000名全职等效(FTE)员工中有62起。矿坑受伤发生率较高,但工厂的发病率较高。此外,地表SSG矿的非致命STF事件每年导致约23800个总误工日,采矿业每年估计成本为1750万美元。2013年至2017年期间,与报告的伤害无关但与矿山安全与健康管理局(MSHA)检查中发现的STF危险相关的评估违规行为使采矿业每年损失约300万美元。根据本研究分析的数据,从较高位置跌落造成的成本负担更高;然而,在同一高度的跌倒事件数量和发生率更高。
