Quantitative Safety Risk Assessment - QRA

A Quantitative Safety Risk Assessment (QRA) is a valuable tool for determining the risk of the use, handling, transport and storage of dangerous substances. QRAs are used to demonstrate the risk caused by the activity and to provide the competent authorities with relevant information to enable decisions on the acceptability of risk related to developments on site, or around the establishment. It aims to reduce the likelihood of negative outcomes by taking into account the probability of adverse events occurring, their severity if they occur, and their potential impact if they do occur. Quantitative risk assessment uses probabilistic models to potential threats and vulnerabilities.
