Abstract

Janitorial services are an essential part to keep workplaces functional. Janitors consider the job labor intensive, and that workload is increasing in recent years. The most impacted body parts are hand/wrist, shoulder, and back in this population. This paper reports a compendium of physical ergonomics exposure assessment using three observational methods. The composite Strain Index (COSI) for hand/wrist, Manual Task Risk Assessment (ManTRA) for shoulder, and Recommended Cumulative Recovery Allowance (RCRA) for shoulder and back, were chosen for their capability to capture the complex and dynamic nature of all tasks performed in a janitorial job. Forty-six unique cleaning task-location-tool combinations received assessments, and the risk scores from the three methods are compiled into a compendium. This information can help practitioners to estimate the risk for a job, or designers to plan jobs for a team of janitors so the risks can be mitigated with careful task assignments.

在日常清洁活动中暴露于手、肩和腰部的物理工效学简编
清洁服务是保持工作场所正常运转的重要组成部分。清洁工认为这项工作劳动强度大,而且近年来工作量不断增加。在这一人群中,受影响最大的身体部位是手/腕、肩和背部。本文报告了使用三种观察方法进行物理工效暴露评估的简编。之所以选择手/腕部综合劳损指数(COSI)、肩部手动任务风险评估(ManTRA)以及肩部和背部建议累积恢复量(RCRA),是因为它们能够捕捉到清洁工工作中所有任务的复杂性和动态性。有 46 种独特的清洁任务-地点-工具组合接受了评估,三种方法得出的风险分数汇编成册。这些信息可以帮助从业人员估算某项工作的风险,也可以帮助设计人员为清洁工团队规划工作,从而通过谨慎的任务分配来降低风险。

期刊介绍: The journal publishes original contributions that add to our understanding of the role of humans in today systems and the interactions thereof with various system components. The journal typically covers the following areas: industrial and occupational ergonomics, design of systems, tools and equipment, human performance measurement and modeling, human productivity, humans in technologically complex systems, and safety. The focus of the articles includes basic theoretical advances, applications, case studies, new methodologies and procedures; and empirical studies.
