“…In addition, open-literature information was used in some cases to contrast and deepen the information available in the reports. The methodology was integrated under the principle of convergence, from previous research reporting industrial accidents triggered by diverse natural events [ 12 , 18 , 21 , [23] , [24] , [25] , [26] , 29 ]. After the data collection, several analyses and modelling techniques were conducted from diverse perspectives aiming to learn from records to increase vulnerability awareness against lightning strikes.…”

“…Hence, the present research develops a historical analysis of NaTech events triggered by lightning strikes in the process industry with novel elements incorporated. It updates the record of such events up to the end of 2022, in comparison to past studies [ 21 ] and introduces new comprehensive classifications to improve compatibility with recent studies in the NaTech field and process industry safety [ 12 , 18 , [23] , [24] , [25] , [26] ]. Furthermore, the conceptual updates incorporated into the evolution of international standards regarding lightning protection systems have been introduced as technical criteria [ 27 ].…”

“…An important climatic condition is cold waves, characterized by sudden and drastic reduction in air temperature. In the last decade, an increasing frequency of the failure of pipeline systems during the cold-wave period have been reported [6][7][8][9][10], especially the occurrence of pipe bursts (Fig. 1.).…”

Water distribution pipelines play a critical role in delivering safe drinking water to communities, yet their susceptibility to extreme climate events presents significant safety and structural challenges. Recent observations have noted an increase in pipe failures during cold waves, underscoring the need to address these risks. While much research has focused on statistical analysis of pipe failures due to low temperatures, limited attention has been given to the mechanical behavior of pipelines under thermal-induced stress during cold waves. This study addresses this gap by developing a 3D finite element model to investigate the thermal responses and mechanical behavior of buried water distribution pipelines under cold wave conditions. Key parameters including temperature differences, soil temperature reduction rates, pipe wall thickness, and internal water pressure are examined to understand their effects on pipeline stress, strain, and displacement. Results show that as pipe temperature decreases, the pipe contracts, particularly impacting the springline. Over time, pipeline stress transitions from tension to compression. A temperature difference of approximately 18℃ leads to an 85% increase in axial strain and a 6.5% increase in Mises stress. Increasing the rate of temperature reduction minimally affects pipeline stress but significantly impacts displacements. Moreover, increasing pipe wall thickness effectively reduces pipeline stress by 102.8% and axial strain by 17.4%. Higher internal water pressure results in elevated pipeline stress but reduced displacement. These findings underscore the importance of considering thermal-mechanical interactions during cold waves to prevent failures and ensure operational integrity in water distribution pipelines.

“…As suggested by a preliminary study carried out by Ricci et al [26], these extremes may affect differently industrial installation, and a detailed analysis of the cascading events and resulting accident scenarios that may be triggered should be carried out separately. Recently, an in-depth analysis was carried out to assess the possible impacts of cold waves and industrial installations, considering both equipment items and safety barriers [27]. Nevertheless, limited attention was devoted in the literature to the study of heat wave-related accidents.…”

Natech accidents have an increasing relevance due to the growing number of such events and to their severe consequences. Climate change and global warming are intensifying the occurrence and the magnitude of climate-related natural events, further increasing the risk of cascading sequences triggered by natural disasters impacting industrial installations. The present study focuses on Natech triggered by heat waves. The features of this specific category of Natech events were investigated by past accident analysis, collecting an extended dataset of past events. The dataset analysis allowed the identification of the key factors that characterize these accident scenarios, such as the direct causes, the technological scenario that occurred, the substance categories, and the equipment items more frequently involved. The main direct cause of accidents resulted in an internal pressure increase, exceeding equipment design limits. Fire scenarios represent the most important category of technological scenarios that occurred. Besides equipment items handling liquid and gaseous hydrocarbons, waste storage and processing systems also resulted frequently in accidents, due to the self-decomposition and self-ignition phenomena. The analysis of past accidents also allowed identifying some lessons learned, useful to identify specific actions aimed at preventing and/or mitigating the possible occurrence of these accident scenarios.
