Abstract

Generally, these studies discuss the whole body vibration experienced among machine operators during metal stamping process. The objectives of the study are to identify pain, discomfort and occupational injuries that experienced by the stamping machine operators due to whole body vibration exposure, to analyze the WBV exposure experienced by the stamping machine operators during metal stamping process and develop solution to eliminate or reduce whole body vibration exposure. The study was carried out among the machine operators in a metal stamping industry. Ergonomic approach was used as the methodology to achieve the objectives. During the study, three phases assessment which involved measurement of whole body vibration, observation method, whole body vibration measurement and whole body vibration measurement using a rubber pad were conducted. Based on the survey, the author was identified that most of machine operators experienced pain, discomfort and occupational injuries while performed their task. This study has been conducted based on Design of Experiment 23 with two levels of each factor is used. The factors used are machine capacities, machine speeds and working positions. According to the results obtained from the assessment without using any control measure, machine speed was identified as the significant point that contribute to occupational health problems. The design of workstation has been improved using a rubber pad as a solution to reduce whole body vibration exposure. Therefore, the author concluded that a propose control measure is an effective solution to the occupational health enhancement in metal stamping industry.
