Provide the workers for fresh air whom under the well when take place catastrophe and cause poisonous gas or hypoxia (gas blasting, coal and gas blasting, fire etc). This is a personal protective apparatus for breathing system which can generate oxygen in an isolated close cycle by chemical reacting, and be used to provide the wearer with oxygen when exploring a coal mine or in the environment where toxic gases exist or oxygen is deficient. Respirators apply to underground work, entertainment, fire disaster,
toxic gas environment, etc.
Start-up equipment use chlorate, quickly and safety;
