Occupational Strain and Health Hazards of Grinding Workers in Foundry

Das Chandan, Das Suman, Banerjee Debamalya, Samanta Amalendu, Bhattacharyya Bidyut Kumar

Abstract


Grinding is a kind of metal-removal process in which materials are removed by a grinding wheel, containing abrasive grains that act as miniature cutters. This task is common to many industries spread all over the world. The workers in this task have to utilize muscle power depending on types of grinding machines. Grinder exposed themselves to different grades of work and thermal load. The present study was undertaken to assess the degree of strain of two types of grinders during the course of their daily activities. The study was conducted on 20 workers engaged in two types of grinding activities: heavy grinding and light grinding. The thermal environmental parameter was recorded by Ex-tech HT 30 and Ambient Weather WM-4.The physiological responses at work were monitored by Suunto Ambit 3 Peak HR and Barun Thermo scan 5. The finding of the present study is presenting an increasing challenge to health and safety of grinders. If effective prevention measures are taken in the workplace, the workers may not be physically challenged by combined work and thermal stress. The potential impact of combined exposure is not reported to the management due to lack of awareness that they may pose any risk of works and heat-related injuries.
