This study uses the “6.21” LPG explosion at the Fuyang Barbecue Restaurant in Yinchuan, Ningxia, as a case study. A computational fluid dynamics (CFD) model was developed to simulate the event. Findings indicate that propane created a nonuniform concentration field in the restaurant, with concentrations increasing from top to bottom. Pressure–time curves at three kitchen monitoring points (P3, window-left, and ignition point) showed an “M” shape due to structural and turbulence effects. The shock wave’s direct impact led to a “Λ” shape in overpressure time history curves at other first-floor points. Externally, the second-degree burn range for 1 s exposure reached 35.82 m. The hazardous overpressure zone measured 58.3 m long and 21.5 m wide, and the fatality zone extended to 25.1 m. This research offers crucial insights for preventing and investigating LPG cloud explosions in confined spaces.</p>","PeriodicalId":73648,"journal":{"name":"Journal of chemical health & safety","volume":"32 3","pages":"307–319 307–319"},"PeriodicalIF":0.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144133877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the gravimetric analysis of respirable dust (RD) provides only one data point. Based on this background, this study aims to quantify RD concentration and peak RD exposure detected as time-series data using a personal optical particle counter (OPC) for possible applications of exposure monitoring in near-real time. Thirty pairs of side-by-side RD exposure samples were collected (22 personal and 8 static) using the Nanozen DustCount 9000Z1 OPC and SGS (NIOSH 0600). The SGS samples were sent for gravimetric analysis in an ISO 17025:2005-accredited analytical laboratory. A correction equation for the OPC sensor was established using linear regression and was used to correct the RD concentrations that were quantified by the OPC. The RD concentrations quantified by the OPC sensor were strongly correlated with those of the SGS method (<i>r</i> = 0.93), and the Bland-Altman analysis showed a consistent pattern and that, on average, the SGS method measured 0.27 mg/m³ higher than the OPC sensor. The time-weighted average RD_opc concentrations were less than 1.5 mg/m³ for the mine sections sampled; the highest peak RD_opc concentration was 11.51 mg/m³. The results from the side-by-side sampling showed a consistently positive bias, and the Pearson correlation was strong. Thus, the results from Nanozen DustCount 9000Z1 could be corrected using the SGS results and linear regression. The corrected RD concentration can be used to assess the efficacy of the engineering controls in-time. The exposure data from the OPC complement the SGS results by providing additional exposure data such as peak exposure and particle size distribution. From the corrected RD exposure data, the RCS was estimated. Based on the results of this estimate, there is potential for overexposure to RCS at this mine; thus, miners are likely to develop silicosis.</p>","PeriodicalId":73648,"journal":{"name":"Journal of chemical health & safety","volume":"32 3","pages":"326–335 326–335"},"PeriodicalIF":0.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144133901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
