Zinc powder and flakes have excellent thermal conductivity, electrical conductivity, and corrosion resistance, and are increasingly used in the automotive, electronics, and construction industries. Recently, they have also been used in various advanced applications such as energy storage system. However, although powdered zinc metal always poses a fire hazard depending on particle size and handling method, the lack of handling information and unclear related regulations are causing confusion in response procedures. Therefore, we analyzed recent fire cases that occurred at workplaces handling zinc powder and, through focused experiments, confirmed the reaction with moisture according to zinc powder particle size and the risk of ignition according to the handling environment. Additionally, we studied the most effective method to respond to zinc powder fires by comparing the performance of fire extinguishing agents. The conclusions and results of the study can be actively utilized in establishing preventive measures through fire risk assessment of zinc powder, and by verifying the possibility of using water-based fire extinguishing agents to extinguish zinc powder metal fires, it suggests the need for improvement of response systems and review of related regulations.
