While there is a relatively well-established knowledge and understanding of hazards and associated risks for gaseous hydrogen at ambient temperature, several knowledge gaps are yet open regarding the behaviour in incident scenarios of cryogenic hydrogen, including LH<sub>2</sub>. This paper aims at presenting the models and tools that can be used to close relevant knowledge gaps for hydrogen safety engineering of LH<sub>2</sub> systems and infrastructure. Analytical studies and computational fluid dynamics (CFD) modelling are used complementarily to assess relevant incident scenarios and compare the consequences and hazard distances for hydrogen systems at ambient and cryogenic temperature. The research encompasses the main phenomena characterising an incident scenario: release and dispersion, ignition, and combustion. Experimental tests on cryogenic hydrogen systems are used for the validation of correlations and numerical models. It is observed that engineering tools originally developed for hydrogen at ambient temperature are yet applicable to the cryogenic temperature field. For a same storage pressure and nozzle diameter, the decrease of hydrogen temperature from ambient to cryogenic 80 K may lead to longer hazard distances associated to unignited and ignited hydrogen releases. The potential for ignition by spark discharge or spontaneous ignition mechanism is seen to decrease with the decrease of hydrogen temperature. CFD modelling is used to give insights into the pressure dynamics created by LH<sub>2</sub> vessels rupture in a fire using experimental data from literature.</div></div>","PeriodicalId":16291,"journal":{"name":"Journal of Loss Prevention in The Process Industries","volume":"95 ","pages":"Article 105606"},"PeriodicalIF":3.6,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143510081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on these findings, we propose an enhanced model designed to provide robust data support for risk warning initiatives. After analyzing over 600,000 accidents from 1971 to 2023, we observe that the annual number of accidents has exceeded 20,000 since 2021. This trend underscores the urgent need to enhance the accuracy of accident risk warnings to mitigate economic losses. The study further reveals that most accidents occur between 6:00 and 11:00, with 91.7% of these incidents resulting in spillage. This finding underscores the critical need for a robust emergency response plan specifically tailored to address spillage events. To address the issue of performance degradation of models in large-scale datasets, the “SF-T0.25” model using a stacking algorithm was developed, which was validated using more than 70,000 spillage accident records from 2021 to 2023. The results show that the prediction accuracy of the model reaches 0.9628, which is better than the parameter-adjusted ET model (0.94981). The SF-T0.25 model also performs well in indicators such as the Jaccard similarity coefficient and the cross-entropy. The mean value of Jaccard similarity coefficient in predicting the type of accident weather conditions is more than 0.97 and the mean value of Cross-Entropy Loss in predicting the range of instantaneous speed of vehicles during accidents is less than 0.05, which proves that the model can provide reliable data support for early risk warning of hazardous materials transportation.</div></div>","PeriodicalId":16291,"journal":{"name":"Journal of Loss Prevention in The Process Industries","volume":"95 ","pages":"Article 105594"},"PeriodicalIF":3.6,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143519200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proper management of this hazard is partially reliant on accurate ignitability data for flammable dusts. The minimum ignition energy (MIE) of a dust is one such quantification, which quantifies the likelihood of ignition for a flammable dust based on experimental evidence. Since the industrial revolution, many experimental methods have been developed for testing the MIE of ignitable dusts. This manuscript presents a novel, small-scale device for testing dust cloud MIEs. This device was designed to be modular and to easily integrate into the existing hardware of the popular Kühner MIKE3 MIE testing device. Since the Kühner MIKE3 is a well-trusted device that produces repeatable MIE results, the new small-scale device was designed specifically to return comparable MIEs. The device was designed to create a dust dispersion similar in dynamics to those of the Kühner MIKE3, such that ignition behavior in the two devices would be similar. A novel technique of using high-speed video to holistically analyze in-tube dust dispersions is presented. Experimental data from the video technique was used to optimize the dispersion dynamics in the small-scale device. Functionality of the small-scale device was verified by the testing of three control dusts in both the new small-scale device and the MIKE3, with MIE results in agreement for each dust. The small-scale device presented in this work is fast and simple to operate and requires much less sample than traditional MIE testing methods. These features make it ideal for testing expensive or hazardous dusts., or dusts for which sample quantity is limited.</div></div>","PeriodicalId":16291,"journal":{"name":"Journal of Loss Prevention in The Process Industries","volume":"95 ","pages":"Article 105580"},"PeriodicalIF":3.6,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143478689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluated the random risk of natural gas pipelines, while considering the failure probabilities and consequences, and constructed a non-periodic preventive maintenance decision model based on the corrosion state and potential risk. First, we developed a random process model for simulating the corrosion of natural gas pipelines; a random risk assessment model was established by considering the failure probability with respect to the random corrosion depth and failure consequence with respect to the random corrosion length. Second, based on the results of random risk assessment, a preventive maintenance policy was developed pertaining to the corrosion conditions and future risks. Third, a maintenance decision model, with the aim of minimising the average maintenance cost in a finite horizon, was established to determine the optimal preventive maintenance risk threshold and inspection cycle for natural gas pipelines. Finally, we conducted an experiment while considering the corrosion data of a real pipeline.

One of the primary mechanisms is capability of water in reducing ambient, flame and fuel temperature. Water is capable to displace oxygen and flammable gases from fire area and attenuate radiant heat. Water is also capable of wetting the fuel and preventing the spread of flames to unburned fuel. Secondary mechanism is ability of trapping toxic particles and other smoke or dust particles from the air. Kinetic and dilution effect should also be mentioned. Due to these mechanisms, water mist systems are considered effective in fire suppression and extinguishing. In practice, we can encounter water mist systems from commercial buildings, historical buildings to marine vessels. Water mist can also be used in other applications beyond fire protection.

A wide flexible selection of natural hazards is proposed, emphasizing the need for a “location priority factor” that considers hazard spatial influence, the conditional probability of NaTech events based on industrial macro-sectors, and cascading effects between hazards. Additionally, interactions among neighboring infrastructures are introduced as an extra hazard factor. To ensure consistency with prior research and historical NaTech data, a broader set of harmonized industrial item categories is defined. The study highlights the dynamic vulnerability of critical items within a plant, considering their layout proximity and functional interconnections. Moreover, multi-risk assessment is improved by integrating quantitative criteria for ratings derived from historical NaTech analyses. An enhanced index for assessing major industrial accident potential based on hazardous substance criteria is proposed in alignment with European legislation. The proposed decision matrix combining independent evaluations of infrastructure and substance-related factors may support risk assessment through varying levels of tolerance, guiding preparedness strategies for industrial systems.</div></div>","PeriodicalId":16291,"journal":{"name":"Journal of Loss Prevention in The Process Industries","volume":"95 ","pages":"Article 105588"},"PeriodicalIF":3.6,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143453501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
