The Use of Accident Indicators for Risk Assessment Monitoring in Design and Construction Phase of Pelletizing Project, 2016-2017




To preserve workforce and reduce accidents, requirement in industrial HSE management system relies on prevention before occurrence. The aim of this study was to evaluate the safety conflicts by preliminary hazard analysis (PHA) method and monitoring of subjective risk assessment by safety performance indicators. This descriptive–analytical study was carried out on 30 jobs in the Yazd pelletizing project in the 2016-2017. After classifying risks in Preliminary Hazard List (PHL), severity and probability of the risk and the initial risk assessment code (RAC1) were calculated. Acceptance risks were eliminated of the PH L, and the remainder for corrective actions was recorded in the form of PHA and then the secondary risk assessment code (RAC2) was determined. Annual safety performance indicators were also calculated for these jobs and finally, statistical analysis was conducted on the relationship between mentioned indicators and the results of risk assessment. In order to determine the relationship between RAC1 and safety performance indicators (AFR, ASR, and FSI), a Pearson correlation coefficient was calculated. Among different occupations, the highest accident frequency rate and risk related to welding jobs. The relationship between RAC1 and RAC2 showed a significant difference between risk assessment code before and after corrective action. Our result was an indicative of the effectiveness of corrective actions. Regarding the monitoring of risk assessment by accident indicators and significant relationship between them, subjective risk assessment research can be used for further safety in working environments.
