Workplace injuries in the grain handling industry are common, yet little research has characterized worker injuries in grain elevators across all hazard types. Learning from past injuries is essential for preventing future occurrences, but the lack of injury information for the grain handling industry hinders this effort. The present study addresses this knowledge gap by using data from over 7000 workers' compensation claims reported from 2008 to 2016 by commercial grain handling facilities in the U.S. to characterize injury costs and severity. The total amount paid for each claim was used as a measure of injury severity. The effects of employee age and tenure, cause of injury, and body part injured on the cost of work-related injuries were investigated. Contingency tables were used to classify the variable pairs. The chi-square test and chi-square residuals were employed to evaluate the relationship between the variable pairs and identify the at-risk groups. Results showed that the employee age and tenure, cause of injury, and body part injured have a significant influence on the cost paid for the claim. Several at-risk groups were identified as a result of the analyses. Findings from the study will assist commercial grain elevators in the development of targeted safety interventions and assist grain elevator safety managers in mitigating financial and social losses from occupational injuries.
谷物处理行业的工伤事故很常见,但针对各类危险类型,很少有研究对谷物升降机中的工人受伤情况进行描述。从过去的工伤事故中吸取教训对于预防未来事故至关重要,但谷物处理行业缺乏工伤信息阻碍了这一努力。本研究通过使用美国商业谷物处理设施在2008年至2016年期间报告的7000多份工人赔偿申请数据,来描述工伤成本和严重程度,从而填补这一知识空白。每份申请的支付总额被用作衡量工伤严重程度的指标。研究了员工年龄和任期、受伤原因以及受伤身体部位对工伤成本的影响。使用列联表对变量对进行分类。采用卡方检验和卡方残差来评估变量对之间的关系,并识别高危群体。结果表明,员工年龄和任期、受伤原因以及受伤身体部位对申请支付成本有显著影响。分析确定了几个高危群体。该研究的结果将有助于商业谷物升降机制定有针对性的安全干预措施,并帮助谷物升降机安全管理人员减轻职业伤害造成的经济和社会损失。
