Slips, trips, and falls from mobile mining equipment have been documented for decades. However, little research has been conducted to determine the events precipitating these incidents during ingress or egress. This study examined slips, trips, and falls sustained during ingress or egress from front-end loaders to determine the frequencies of factors that may contribute to injuries. Non-fatal injuries, when getting on or off of front-end wheel loaders specifically, were identified, coded, and analyzed from the Mine Safety and Health Administration's accidents, injuries, and illnesses database. Overall trends, events that precipitated the injury, injuries sustained, contributing factors, location of the individual, and equipment characteristics were analyzed. More incidents occurred during egress (63%); and egress is believed to be more hazardous than ingress. Foot slips were the most common event that precipitated the incident and the leading cause of these was contaminants on the equipment. Misstep, loss of footing, and step on/in related incidents were more common during egress and are likely due to the operator's reduced visibility when descending a ladder facing the equipment, limiting their ability to detect hazards. Egress also makes an operator less capable of avoiding unsafe ground conditions as indicated by the significant number of step on/in injuries occurring on the ground during egress. Most of the front-end loaders associated with the incidents were found to have bottom rungs with flexible rails, which may also increase fall risk during egress due to inconsistent rung heights and lengthy transition areas from the ground, through the flexible-railed rungs, to the rungs with rigid rails. Recommendations are provided to reduce the risk for slips, trips, and falls from mobile mining equipment.

前端装载机操作员进出时伤害分析

移动采矿设备导致的滑倒、绊倒和跌倒已有数十年的记录。然而，很少有研究来确定在进出期间引发这些事件的事件。这项研究检查了前端装载机进出期间发生的滑倒、绊倒和跌倒，以确定可能导致受伤的因素的频率。从矿山安全与健康管理局的事故、伤害和疾病数据库中识别、编码和分析非致命伤害，特别是在上下轮式装载机时。分析了总体趋势、促成伤害的事件、持续的伤害、促成因素、个体的位置和设备特性。出口期间发生了更多事件（63%）；并且出口被认为比进入更危险。足部滑倒是引发事故的最常见事件，其主要原因是设备上的污染物。疏散、失足和踩踏/踏入相关事件在出口期间更为常见，这可能是由于操作员在面向设备的梯子下下降时能见度降低，从而限制了他们检测危险的能力。出口还使操作员不太可能避免不安全的地面条件，如在出口期间发生在地面上的大量踩踏/踏入伤害所表明的那样。发现与事故相关的大多数前端装载机的底部横档都带有柔性导轨，由于横档高度不一致和距离地面过长的过渡区域，这也可能增加出口时的坠落风险，通过柔性导轨的横档，到达带有刚性导轨的横档。提供了降低移动采矿设备滑倒、绊倒和跌倒风险的建议。
