The number of fires in Korea is increasing every year, with an average of more than 20,000 fires occurring each year. In addition, today's rapid economic development is leading to the increase in the use of hazardous substances such as gas and oil, along with the complexity of industrial facilities, larger buildings, and taller buildings, and the side effects thereof are also increasing.

For example, most buildings subject to firefighting, excluding private houses, are equipped with various equipment to prepare for fire, and among them, the sprinkler system is the most important equipment as a fire extinguishing system.

Recently, as the need for simple sprinklers has emerged due to frequent house fires, interest in simple sprinkler systems is increasing, and their distribution is expected to spread as firefighting laws are strengthened.

This is a situation where numerous casualties and property damage occur due to fire every year, and especially during the winter season, the risk of fire occurring increases due to the rapid increase in the use of various electric heating appliances. The simple residential sprinkler system is installed in general homes, small retail facilities, restaurants, etc. where sprinkler fire extinguishing equipment, a type of automatic fire extinguishing equipment, is not applicable. It can be installed simply by branching off from the water pipe, and restaurants, etc. can be installed by an unspecified number of people. Because it is used a lot, the risk of fire increases. There is a need to install simple sprinkler systems in general homes and restaurants to extinguish fires at an early stage and minimize damage to life and property.

However, the existing sprinkler system is mainly installed in large buildings, so there is no system to protect general homes and small-scale multi-use businesses from fire. Therefore, by allowing students who will be responsible for future firefighting to plan, design, manufacture, test, and evaluate simple sprinkler systems, which can be considered the most important in the field of firefighting, against the background of theoretical education, this will help students gain confidence and prepare them for entering the industry in the future. In this case, let them play a leading role in the development of a simple sprinkler system.

Therefore, in the field of firefighting, if you do not understand the sprinkler system, it is difficult to understand the series of processes from when a fire starts to being extinguished. However, although lectures have been given to students majoring in firefighting on both theory and practical operation, unfortunately, the incidental costs and other conditions required for product production are not feasible, so students are still required to manufacture the overall system themselves and operate it. It is true that we were unable to create an opportunity for easy understanding. In addition, the existing method had the problem of being exposed to a defenseless state in the event of a fire because a simple sprinkler system was not installed.
