The chemical oxygen self rescuer is a protective device for the human respiratory system. It is mainly used for underground mining operations in coal mines. Miners can wear this self-rescuer in time when there is a disaster in the mine, resulting in lack of oxygen in the environment or high concentrations of toxic and harmful gases that endanger their lives. , Realize the protection of the respiratory system, and evacuate from the disaster area.
The operating environment of the chemical oxygen self rescuer: (1) It is not limited by the concentration of asphyxiating gas and oxygen in the operating environment; (2) The operating environment temperature is 0-40℃.
Characteristics and requirements of chemical oxygen self rescuer: (1) The initial oxygen generation starting device adopts chlorate oxygen candle, which is fast, safe and reliable. (2) KO 2 sheet oxygen generator is used, with uniform and sufficient oxygen generation, less dust, stable performance, low inhalation temperature, and low respiratory resistance. (3) The use of glass fiber bai combined with dust-proof mat has good dust-proof effect and is comfortable to wear.
