The use of dust in industrial applications has increased, posing a significant threat to production safety through dust explosions. This paper explains the principles of dust explosions, which depend on combustible dust, oxidizers, ignition sources, and appropriate concentration conditions. Hazard assessment methods include qualitative checklists, hazard and operability studies, quantitative methods such as the Dow Fire and Explosion Index, accident tree and event tree analysis, and comprehensive approaches like the Analytic Hierarchy Process (AHP) and fuzzy comprehensive evaluation. Prevention technologies focus on optimizing processes to reduce dust, controlling concentrations through ventilation and dust removal, eliminating ignition sources, and implementing explosion relief and isolation measures. By systematically reviewing research advancements, this paper aims to provide theoretical and practical references for preventing dust explosions and ensuring production safety in the industrial sector.
