Individual and social risk assessment

PSI “Risks un audits” uses software Effects and Riskcurves, developed by Netherlands Organisation for Applied Scientific Research (TNO), which are helpful in carrying out individual and social risk assessment.

Individual and social risk assessment of dangerous objects are widely used in other countries of  Europe and other world, and the results are the most appropriate for characterization of risk object’s overall risk level as well as for spatial planning.

The individual risk assessment provides analysis of the overall probability of all potential emergency scenarios to cause death in certain place against the dangerous object.

The individual risk area is illustrated as risk isolines around the source of risk:

In social risk assessment we consider the overall risk caused by the risk object under analysis, but contrary to individual risk assessment it includes also analysis the number of people being present in the risk area. Thus social risk characterizes the probability of death of certain number people in case of industrial accident.

Social risk curve is visualized in social risk matrix:

Identification of individual and social risk is a component of our quantitative risk assessments, which are developed in compliance with the principles and output data of  Netherlandic guidelines of quantitative risk assessment (“Guidelines for quantitative risk assessment”, “Purple Book” CPR 18E).

Software Effects and Riskcurves have been developed on the basis of principles embodied in Netherlandic guidelines for quantitative risk assessment and fully ensure, that risk assessment is developed pursuant to these guidelines.

To be proficient users of the mentioned computer modelling tools, our experts have gained necessary knowledge at the developers of computer programs in Netherlands. More than 15 years of expertise in the industrial risk field and knowledge in carrying out quantitative risk assessments in accordance with guidelines for quantitative risk assessment provides high quality risk assessments which meet modern requirement.
