Role of Inherently Safer Concept in Hazard Identification and Risk Assessments in Viaduct Work

Abstract

injuries. newlineVarious aspects overlooked, intentionally or unintentionally, during hazard identification and risk assessment using HIRA are identified and included in order to strengthen the existing techniques. A framework, based on the twelve different considerations identified after rigorously sifting through various method statements has been developed. Each consideration, in the developed framework, has six sub categories or concern areas. Quantification of each area is done based various study and analysis of data and set of questionnaire and survey conducted at work site. newlineThese considerations have been quantified and risk multiplication factor (RMF) is generated. Finally, a modified risk level (MRL) is obtained by multiplying initial risk level with RMF. newline
