A methodology for the identification of confined spaces in industry

Work in confined space is a high-risk activity posing a serious life-threatening hazard to workers who perform it. Accidents in confined spaces frequently lead to multiple fatalities. The cause of accidents and fatalities due to confined space work is related to the lack of awareness about the presence and the risks of such hazardous workplaces. This paper introduces a methodology for the identification of confined spaces in industry. The aim is to provide a useful tool for helping researchers and practitioners to recognize of confined spaces in industry. Four different characteristics of confinement are investigated: geometric features, access, internal configuration, and atmosphere and environment. The proposed methodology includes the definition of the Confined Space Risk Index (CSRI) for the analysis of the risk related to the investigated confined space. Finally, two case studies show the application of the proposed methodology to two suspected confined spaces in industry
