Various types of dust and gas masks have been developed and used in order to avoid harming human health in medical or firefighting, mine shafts, or industrial sites where harmful gases and dust are generated. However, these masks are dust filters and neutralizers. The purifiers containing are directly connected to the mask, which makes the user feel strong and frustrated because they have to inhale when they wear and breathe. There was a big flaw that the breathing disorder became worse when it was stuck. In particular, for workers and firefighters who need to act in flames to save lives in a mine pit with heavy equipment or in the event of a fire, it is easy to cause a breathing disorder with prevention and respiratory mask only due to excessive respiratory volume due to excessive momentum. As a result, various types of respiratory diseases frequently occur, and serious solutions are required.

When cut off, the harmful gas or dust is inhaled by the worker right away, which can cause fatal health and, in severe cases, cause the worker to die due to respiratory failure. In the environment, workers wear masks and act This is because it is not possible to contact each other during the work or to inform the workers around the dangers, so when the work speed is slow or severe, a large number of victims are exposed in case of accidents. As there is no choice but to carry a watch or use a hand signal, the economic burden and the worker's eyes at the time of hand signal are always concentrated at the work site, so the hand signals are not transmitted properly, which is not enough to effectively warn of the danger situation. Several problems have arisen, such as should be.
