A study developing the dry powder fire extinguishing system inside the simulated machinery spaces of small ship was performed. Fire tests were conducted inside the compartments having volums 8$m^3$, 2.9$m^3$ and 4.5$m^3$ respectively. The openings and fans were established on the walls of the compartments. Diesel oil was used for the test fuel. In addition fire extinguishing nozzles using dry powder were installed downward at ceiling and horizontally at the wall or conner. All fires in the test were extinguished under system activation and there was no reignition.

A class D fire or combustible metal fire is characterized by the presence of burning metals. Only certain metals or metal compounds are flammable, including sodium and lithium. General fire extinguishing agents, such as dry chemical powder, water-based fire extinguish agents, and carbon dioxide, cannot be used in class D fires. This is because these agents cause adverse reactions or are ineffective. In addition, the amount of usage of combustible metals is increasing due to continuous development of the semiconductor and fuel cell industries. Despite this, Korea does not have standards and laws related to combustible metal fires. This paper suggests directions of the class D fire management policies to reduce the class D fire risk and impact by analyzing the standards and laws related to class D fires and combustible metal fire cases. The factors to make laws on class D fire prevention and response systems, and management system of dry sand were determined. These results may be used to help reduce the risk of class D fires and improve the response abilities.
