Improvement of the hazard identification and assessment in application of the Seveso II directive (part II)

Abstract : The Council Directive 96/82/EC of 9 December 1996 on the control of major-accident hazards involving dangerous substances, known as Seveso II Directive, aims at the prevention of major accidents in high risk industries, and the limitation of their consequences for human beings and environment. Although rules are well established to identify maximal hazard potential, there is no recognised method for taking into account, in the assessment of risk level, safety devices and safety management systems implemented by operators. This paper deals with the second stage of a global methodology aiming at better assessing benefits gained from safety devices and safety management systems, through accident scenarios selection. The methodology presented in this paper enables risk assessors and competent authorities to identify Reference Accidents Scenarios (RAS), by taking into account the influence of some safety barriers, in accordance with the Seveso II Directive requirements. This method could help stakeholders involved in the public risk-based decision-making process to evaluate the safety level of high-risk establishments. Since the risk management decisions are based on the risk assessment [12], and since the choices and hypothesis to define the RAS are arbitrary, there is a need to reach a consensus among all the stakeholders to limit the discrepancy in the decision and improve the transparency.
