ZH15 isolated chemical oxygen self-rescuer

Isolated chemical oxygen self-rescuer
Isolated chemical oxygen self-rescuer, minute isolation self-rescuer (coal mine self-rescuer) is an isolated closed-circuit circulation personal respiratory system protection device that uses chemical reactions to generate oxygen. Restricted by the concentration of asphyxiating gases and oxygen in the environment, the ambient temperature is ~°C. It is mainly used in coal mines and other underground mining operations. When disasters occur in the mines, there will be a lack of oxygen in the environment or high concentrations of toxic and harmful substances. When gas threatens life safety, miners can wear this self-rescuer in time to protect the respiratory system and evacuate from the disaster area. At the same time, this coal mine self-rescuer can be used as an auxiliary respirator for the mine rescue team, in the case of poisonous gas leaks in petroleum, chemical industries and laboratories, etc. Escape, various tunnel excavations and underground engineering hypoxic and poisonous gas environment escape as well as protective self-rescue equipment.
The working principle of the isolated chemical oxygen self-rescuer is that the water vapor and carbon dioxide exhaled during breathing react with the oxygen-generating agent to generate gas with higher oxygen content. When inhaling, the oxygen stored in the air bag passes through the medicine. From the can to the mouthpiece, it enters the human respiratory tract and completes the entire breathing cycle.
Main features
Using chlorate oxygen candle as the initial oxygen generation starting device, oxygen generation is fast, safe and reliable.
Using flaky oxygen generating agent, the oxygen generation is uniform and sufficient, with less dust, stable performance, low suction temperature and small breathing resistance.
Using glass fiber composite dust-blocking pad, it has good dust-blocking effect and is comfortable to wear.

Precautions
. When wearing an isolated chemical oxygen self-rescuer to evacuate a disaster area, be sure to tighten the mouthpiece and nose clip, and never remove the mouthpiece and nose clip midway
. The oxygen generated by the oxygen generating agent is drier and hotter than the ambient air temperature, but it is harmless to the human body
. Do not compress the air bag when wearing it to prevent damage to the air leakage
. Wearing an isolated chemical oxygen self-rescuer requires accurate operation Quickly, users must undergo pre-training and pass the exam before they can be equipped.
