A Hierarchical Approach for the Evaluation of Chemical Process Aspects from the Perspective of Inherent Safety

Assessment of chemical process hazards in early design stages

“…In the EHS method , substances are assessed in 11 effect categories (mobility, fire/explosion, reaction/decomposition, acute toxicity, chronic toxicity, irritation, air mediated effects, water mediated effects, solid waste, accumulation and degradation). The assessment procedure is explained in detail in Koller et al (2000) and Shah et al (2003).…”

“…Since the batch/semi-batch reactor was already presented in earlier work (Shah et al, 2003), it will only be summarized here while the other equipment units will be presented in detail.…”

“…A first version of SREST-layer-assessment method was presented by Shah, Fischer, and Hungerbühler (2003). The method consists of different layers i.e.…”

Development of environmental consequence index (ECI) using fuzzy composite programming

“…The use of fuzzy logic reduced the uncertainty involved in the selection of hazard values. Shah et al [23] developed a hierarchical approach with safety, health, and environment at different layers. Further, Paralikas and Lygeros [5] proposed a methodology based on both hierarchical approach [23] and fuzzy logic [7,8] for relative ranking of fire hazard of chemical substances and installations.…”

“…Shah et al [23] developed a hierarchical approach with safety, health, and environment at different layers. Further, Paralikas and Lygeros [5] proposed a methodology based on both hierarchical approach [23] and fuzzy logic [7,8] for relative ranking of fire hazard of chemical substances and installations. The substance fire hazard index (SFHI) focuses on the major accident hazards of the substances and the consequences index (CI) assesses the consequence potential of an accident at the facility.…”
