“…To mitigate these risks, the requirements for fireproof materials in clean rooms are more stringent than for other plant areas. For example, according to Chinese standards, the fire protection zone and evacuation distance of this area far exceed the requirements of GB 50016-2014 [47] in the Code for Fire Protection Design of Buildings [48]. Additionally, it is crucial to consider the risk of structural damage and instability due to explosions when choosing construction materials.…”

In the realm of sustainable advancements, high-tech electronics plants have evolved concomitantly with the innovations in environmentally conscious high-tech manufacturing. Nonetheless, the potential for fires in these establishments presents a profound challenge, jeopardizing both human resources and assets, while also bearing ecological implications. However, difficulty exists in understanding the system composition and fire protection features specific to the production environment. Meanwhile, sustainable development-oriented organizational countermeasures for fire resilience are rarely explored in the operations environment. Through a literature review, hypotheses development, an industrial survey, and PLS-SEM analysis using data from 84 questionnaires, this research aims to fill this gap by analyzing the system composition of high-tech electronics plants and its influence on fire resilience, emphasizing the organizational perspective. This study delves into the fire resilience of high-tech electronics plants, drawing particular attention to the imperative of fire prevention, detection, and mitigation measures. The discourse is framed within the paradigm of design-for-sustainability thinking, underscoring the integration of sustainable practices in enhancing fire resilience. By examining the interplay between various functional and organizational system composition elements, three key aspects are extracted to enhance fire resilience: (1) fire protection design measure improvement, (2) sustainable and fireproof construction facility, and (3) organizational management support. The findings contribute to a better understanding of the complex nature of high-tech electronics plants, and provide actionable insights for enhancing both fire resilience and sustainable practices in these establishments.

“…The simulation ran for 600 s. The HRR is a key parameter to describe the fire process, and its value determines whether the simulation is consistent with the actual situation. Depending on the measurement of the physicochemical property data of high alcohols in the early stage, the specify heat of combustion of 53 vol% liquor was set to 29,636 kJ/kg, and the HRR was set to 455 kW/m 2 17 . A medium-speed fire was selected in the “T-square” fire-growth model 30 .…”

“…Currently, the research object in experiments on the water mist fire extinguishing effect is mostly ethanol pool fire, and few scholars have studied the effectiveness of the water mist fire extinguishing system in the case of fires in liquor warehouses. Although the concentration of most ethanol combustibles considered in previous experiments was greater than that in general liquor, based on Chen’s 17 research on the differences in the heat release rate (HRR) and flash point between ethanol–water mixture and Chinese liquor, the overall difference between the ethanol–water mixture and liquor is not significant, and the experimental results pertaining to the ethanol–water mixture can be used to predict the combustion characteristics of Chinese liquor. The feasibility of the water mist system in extinguishing fires in pottery liquor warehouses can be preliminarily assessed from related research on the application of this system in extinguishing ethanol pool fires.…”

Clean fire extinguishing systems applicable to the pottery jar liquor warehouse are in demand. In this study, taking 53vol% liquor as the research subject, fire models of various clean fire extinguishing systems comprising water mist, liquid carbon dioxide (LCO2) and liquid nitrogen (LN2) were established using a fire dynamic simulator to determine their fire extinguishing effect. A feasibility assessment of systems was performed under different fire source types, fire source sizes, and ventilation conditions. The fire extinguishing efficiency was analyzed in terms of the fire extinguishing time, oxygen concentration, and space temperature. The results showed that the success rate of the LCO2 and LN2 fire extinguishing systems was 100%, whereas the success rate of the water mist fire extinguishing system was 95%. In terms of reducing the oxygen concentration at the bottom of the space and the temperature in the space, the LCO2 system exhibited the best performance, followed by the LN2 system, and lastly the water mist. Under different ventilation conditions and fire source types, the LCO2 fire extinguishing system was least affected, whereas the effectiveness of the water mist fire extinguishing system reduced under natural ventilation conditions, and the extinguishing efficiency of the LN2 fire extinguishing system was affected by the fire source type. Overall, the LCO2 system presented more advantages in extinguishing fires in pottery jar liquor warehouses and can provide a new idea for the development and application of clean and efficient fire extinguishing systems.

Electronic nose, as a non-destructive instrument, is widely used in the field of gas analysis. In this work, E-nose was employed to distinguish wines and Chinese liquors by means of a machine learning technique. First, a multi-hidden layers Back-Propagation Neural Network (BPNN) was designed to build an identification model for the classification of different wines. Then, a BPNN-based transfer-learning framework was developed with minimal changes to the architecture of the BPNN-based model which was trained on the wine sample dataset. Experimental results revealed that the BPNN-based model performed with a 98.27% accuracy in identifying different wines, and the BPNN-based transfer-learning framework performed with a 93.4% accuracy in identifying Chinese liquors by only retraining the output layer. This reduced the model training costs compared with the complete retraining of a new classification model. Results demonstrated the effectiveness of the proposed BPNN-based transfer-learning model, which was capable of identifying different kinds of wines based on their own properties and could be easily applied to the classification of Chinese liquors. The model-based transfer learning framework offered promising potential for different classification tasks of various beverage.
