To enhance safety protocols and industrial explosion prevention strategies for TC4 titanium alloy dusts, this study investigates the suppression effects of melamine pyrophosphate (MPP), CaCO<sub>3</sub>, and TiO<sub>2</sub> on flame propagation characteristics using an improved Hartmann tube apparatus. The explosion suppression mechanisms of these three agents are analyzed through detailed explosion residue examination. The results indicate that as suppressant content increases, flame fronts gradually transform into regular parabolic shapes, while bright luminous regions progressively contract until dust extinction occurs. The presence of suppressants significantly reduces the flame propagation velocity of the mixed dust. With increasing suppressant concentration, the time required for flame propagation velocity to reach its peak increases, while the maximum flame propagation velocity continuously decreases. MPP suppresses TC4 titanium dust explosions through both physical mechanisms (heat transmission, cooling, and hindering oxygen) and chemical mechanisms through capturing free radicals within chemical reaction. In contrast, suppression effects of CaCO<sub>3</sub> and TiO<sub>2</sub> on TC4 titanium alloy dust explosion primarily manifest through physical mechanisms such as cooling, impeding oxygen, and heat transfer.</div></div>","PeriodicalId":16291,"journal":{"name":"Journal of Loss Prevention in The Process Industries","volume":"98 ","pages":"Article 105733"},"PeriodicalIF":3.6,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144563488","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 process is predominantly governed by initial conditions, with specific material characteristics exerting measurable influences. For example, dust with good dispersibility has a higher tendency to form clouds and stay airborne. Dust prone to breakage is more likely to be distributed in smaller sizes. This study develops an experimental approach employing sequential particle size analysis through a dry dispersion laser diffractometer. Nine industrially relevant dust samples (<em>i.e.</em>, ascorbic acid, corn starch, lycopodium, niacin, potato starch, skimmed milk, sulfur, wheat flour, and wood) were characterized under controlled dispersion pressures from 0.1 to 3.4 bar. The results show the degree of dispersion or comminution can be distinguished by monitoring the change in size distribution. In general, the fine fraction in the distribution increases at first upon increasing the dispersing energy due to improved dispersion. At higher energies, the amount of fines rises again if the particles start to break up. Sample-specific response patterns emerge in the pressure titration curves: smooth plateaus indicate optimal dispersion for easily dispersible and robust dusts, versus continuous size reduction trajectories revealing poor dispersion and fragile dusts. This qualitative categorizing method enables simultaneous evaluation of both dispersion efficiency and particle integrity, supplementing the pathway for assessing dust explosion hazards across laboratory and industrial scenarios.</div></div>","PeriodicalId":16291,"journal":{"name":"Journal of Loss Prevention in The Process Industries","volume":"98 ","pages":"Article 105734"},"PeriodicalIF":3.6,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144569876","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}

Another option is to use fluorocarbon surfactants or silicone surfactants. These solutions are less effective in fighting fires. This research presents a conceptual framework of suppressing fires involving liquid petroleum products using hydrate foam. When hydrate foam interacts with fire, carbon dioxide released in the dissociation of hydrate displaces the oxidizer from the combustion zone. Hydrate foam absorbs the heat released in combustion, thus cooling the petroleum product and the tank. It creates a buffer zone between the oxidizer and petroleum product surface. This zone limits the combustion front spread. The conducted experiments confirmed the high efficiency of hydrate foam. Optimal parameters were determined for efficient and economical operation of hydrate-based foam fire suppression systems. The data obtained were used to develop a conceptual framework of a fire suppression system for petroleum products in storage tanks. The economic efficiency of the proposed technology was estimated.

EPF still faces significant challenges related to process safety despite its financial advantages. Although existing studies have addressed various aspects of EPF, including risk assessment, design, and economic feasibility, a significant gap remains in the identification and analysis of Major Accident Hazard (MAH) and Safety Critical Elements (SCEs) specific to EPF operations. This study addresses the research problem of identifying potential MAH and the corresponding SCEs to reduce the risk of major accidents in EPF. The study focused on EPF located in three (3) areas: AMJ, BMH, and HGD which are located in West Java, Indonesia. HAZOP and Bowtie methods were employed to systematically identify potential MAH and relevant SCEs in the selected EPF. 32 MAH scenarios on EPF identified in this study. 72 % of accidents have an impact on fire/explosion, which poses a risk to personal safety and facility integrity. Most MAH scenarios on EPF are triggered by two primary causes: overpressure and corrosion. A major proportion of MAH scenarios are identified in equipment such as Separator, Flowline & Manifold, and Scrubber. 188 SCEs were identified in this study. By prioritizing the identified SCEs, maintenance resources can be focused on critical elements that directly prevent or mitigate MAH, thereby improving cost-effectiveness without compromising safety. 74 % were classified as technical/hardware barriers. This highlights the necessity of a robust maintenance strategy to guarantee the reliability and effectiveness of these technical elements over time. Future efforts could also focus on refining the current Bowtie analysis by incorporating quantitative risk modeling methods and on developing performance standards for SCEs, which can be used to enhance the robust maintenance strategy.</div></div>","PeriodicalId":16291,"journal":{"name":"Journal of Loss Prevention in The Process Industries","volume":"98 ","pages":"Article 105728"},"PeriodicalIF":3.6,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144522955","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}
