“…Further, their work discussed the application of ISD principles of "substitution" and "moderation", since process hydrogen can be stored as a less hazardous hydride. Application of ISD principles to plant layout design was presented in a series of two journal papers (Tugnoli et al, 2008a(Tugnoli et al, , 2008b. Their first paper described the application of the inherent safety guidelines and index method for layout design.…”

“…(2) identification of the hazards, which involves all the activities required to identify all the hazards related to the system under examination; (3) qualitative risk analysis, which involves screening activities (for instance through some key performance indicators -KPIs Tugnoli et al 2008) aimed to identify if and where more detailed analyses are required; (4) quantitative risk analysis, which involves quantifying both occurrence probability and expected magnitude of the consequences of each previously identified hazard, in order to estimate overall risk indexes (e.g. individual or societal risk indexes, as defined in Lees, 1996); (5) planning of mitigation measures, which requires implementing all the prevention and protection measures required to reduce the risk level below to some predetermined threshold; and (6) risk monitoring and control, which involves the activities required to avoid that changes in the situation examined would increase the risk level above the acceptable threshold.…”

Dramatic natural events recently stroke several countries worldwide. The impact of the natural events on industrial sites often resulted in large releases of hazardous materials, causing severe technological accidents (Natural-Technological or NaTech events). Industrial operators were often found unprepared or off-guard for unannounced events but also when they had received early warnings. Due to these occurrences, public awareness has raised and the issue of NaTech is now considered as an emerging risk. Due to the climate change and increase in the frequency of some categories of natural disasters, the likelihood of NaTech scenarios is growing, thus NaTech may be also considered as a new risk in some areas of the world. In the present study, the process that ended in the awareness of the scientific community and of the general public toward NaTech has been analyzed. Available tools and knowledge gaps in the assessment of NaTech scenarios are evidenced. The analysis is mainly addressed to the potential impact of flood, lightning, and earthquake events on industrial installations where hazardous substances are present, aiming at the identification of strategies to improve the resilience of industrial facilities to technological accidents caused or intensified by natural hazards.

“…Lee et al's paper suggests the positions that can minimize the domino effect using a nonlinear approach and a computer-aided module [4], but has limitation in applications because of insufficiency of considerations of domino factors (fire, pressure, and missile) and assuming the same risk of all facilities. Recently, the methodologies based on the indexapproach were proposed to solve optimal layout considering safety factors [6,7]. Index approach suggested good guidelines in this area.…”

Accidents involving domino effects are more serious than other type of accidents. Although there have been studies on such accidents, it is still difficult to examine the actual factors and causes since the domino effect is influenced nonlinearly by factors involving flame, overpressure, and flying objects. We considered the case of adding new facilities to an existing system in a given site. The layout of new facilities suggests positions that minimize the domino effects, based on nonlinear optimization taking domino factors into account. We quantitatively calculated the domino risk of each facility through the concept of combined domino factors (flame, overpressure, and missile). Also, we identified variations of domino damage extent of the target system through comparison of the impacts of domino effect when additional facilities were installed. Simulated annealing was adopted for searching optimal positions. As a case study, we applied the proposed method to the case of adding DME storage tanks in the existing LPG charging facilities. The presented framework of the quantitative assessment of domino risk and safety standard for the layout of additional facilities would be useful for proper layout design for improved accident prevention.
