Performance Of Chemical Oxygen Self Rescuer Has The Following Points

Chemical Oxygen Self Rescuer, this product is a respiratory protection device made by oxidizing carbon monoxide contained in the air to carbon dioxide at room temperature using a catalyst. Let's take a look at the performance of those products.

The product performance of Chemical Oxygen Self Rescuer has the following points

1. Air tightness of the exhalation valve: the time to return to normal pressure under negative pressure of 1.47kPa should not be less than 15s.

2. Field of view: the lower field of view should be greater than 40 degrees.

3. Crashworthiness: After testing in accordance with the provisions of GB8560-87, the carbon monoxide resistance, inhalation temperature, respiratory resistance, shell air-tightness, waterproof and moisture-permeability, air-tightness of self-rescuer and air-tightness of exhalation valve, etc., should meet standard requirement.

4. There should be management shelves, belt loops or other backing devices and sealing devices on the shell, and the opening should be marked in dark red.

5. When the Chemical Oxygen Self Rescuer is opened, it should be convenient to wear, and the opening force of the sealing device should be 39～118N.

6. Mouth tools should be made of odor-free rubber materials, and the shape and size of the mouth piece should be suitable for the mouth shape and have good elasticity.

7. Inspiratory temperature: When the concentration of carbon monoxide in the test air reaches 1.0%, the high temperature of the inhaled air does not exceed 65°C, and when the carbon monoxide in the test air reaches 1.5%, the temperature of the inhaled air does not Over 95°C.

8. Respiratory resistance: After the carbon monoxide prevention performance test, the respiratory resistance test should meet the relevant requirements.

9. Smoke filtering ability: The self-rescuer with smoke filtering device, when tested according to the GB8160-87 method, its smoke transmission rate should not be greater than 40%.

10. Air tightness of the shell: no air leakage is allowed at the pressure of 13.34kPa.

11. Chemical Oxygen Self Rescuer Waterproof and moisture permeability: According to the test of GB18160-87, the weight gain of the product shall not exceed 5%.
