Ergonomics Analysis of Working Posture in Household Cleaning Using Technomatix Modeling

Abstract

Household and commercial cleaning is a vital virtue of life. It is advantageous in many ways, and the prime one being it helps to keep an individual healthy. Cleaners working in this area are faced with serious musculoskeletal disorders (MSD), due to prolonged hours in the same posture, repetition in the task, contact stress due to tools or postures. The objective of this study was to explore upper limb musculoskeletal disorders and postural risk among cleaners. In this study, awkward working posture takes on by cleaners in houses has been observed and analyses using ovako working posture analysis system. A housework system model is developed and simulated in computer-aided ergonomics assessment tool Technomatix with implicit cleaners with their specific systematic measurement of the physical properties of the human body. Trunk postural load was found more significantly and also motion angle of the wrist was found repetitive.
