A Study on the Use of Extinguishing Agents to Increase Forest Fire Suppression Efficiency

Water has been known as a substance that can extinguish fires. Water is not only easily sourced from nature, but it has been naturally used to extinguish forest fires because it does not cost anything. However, when rivers, reservoirs, streams, etc. are frozen in winter, it may be difficult to use water for extinguishing. For this reason, other countries are used to fire extinguishing agents that have higher extinguishing performance than water to reduce the extinguishing time and amount of water. In this study, the extinguishing performance of wildfire suppressants was evaluated in line with the trend of other countries’s forest fire extinguishing technology and the fire extinguishing agent system applied to the extinguishing equipment. As a result, when a fire extinguishing agent is applied to forest fire extinguishing equipment, it is possible to extinguish the fire with about 6-20% less than water, and the time required for extinguishing is reduced by about 6-14%. In addition, if a line-froportioner-type gun mixing device is applied to a forest fire extinguishing vehicle, it can be constructed without a separate structural change.
