Chemical oxygen self rescuer structure

It goes without saying that the self rescuer is a device that saves itself. So what are the structural components of the chemical oxygen self rescuer? What are its working processes? 

Chemical oxygen self rescuer working process When the airbag is full of gas, open the exhaust valve to discharge excess exhaled air to ensure that the airbag works under normal pressure and reduce the entry of carbon dioxide and water into the oxygen generating tank, thereby adjusting the rate of oxygen generation and extending the use time. When you feel the lack of oxygen generation when wearing the mask, you can use the quick start device to pull the nylon rope to make the sulfuric acid react with the starter block to generate oxygen immediately to make up for the lack of oxygen generation when you start to wear the mask.

The chemical oxygen self rescuer is composed of oxygen generating tank, air bag, air duct, mouth gear, back waist belt and other components.

Precautions for chemical oxygen self rescuer: 1. When wearing self-rescuer to evacuate from the disaster area, pay attention to the mouthpiece and nose clip. The mouthpiece and nose clip must not be removed midway; 2. The oxygen generated by the oxygen generator is more than The ambient air temperature is dry and hot, but it is harmless to the human body; 3. Do not compress the airbag when wearing it to prevent damage to the air; 4. Wearing a self-rescuer requires accurate and rapid operation. The user must be pre-trained and pass the test before it can be equipped .
