Combustible materials burn with complicated phenomena depending on various conditions of combustion.
Consequently, there are large varieties for fire extinguishments. Here at he National Research Institute of Fire and Disaster, wide range of studies are conducted in a broad range from the basis of fire extinguishments to the elation between fire extinguishants and the global environment. Furthermore the Institute is testing on what types of fire extinguishants are suitable for each type of combustible materials. A tire fire, for example, cannot be extinguished using water but is easily put out with a surfactant solution. Consequently, it is necessary to complete the most appropriate techniques according to purpose by means of integrating the fire extinguisher, means of fire extinguishing, and the like in various ways.
