Look for quality issues about the rescue capsule
The nominal protection time, the oxygen content of the emergency facilities in the internal environment should be in 18.5% ~ 23%, the carbon dioxide concentration of not more than 1%, the methane concentration is less than 1%, the concentration of carbon monoxide is not greater than 0.0024%, the temperature is not higher than 35 degrees Celsius, humidity is not more than 85%, and ensure emergency facilities is always not less than 100 kPa the positive pressure.
Have self-contained oxygen supply system and harmful gas removal facilities. The amount of oxygen is not less than 0.5 liters / min, and ability to deal with carbon dioxide is not less than 0.5 liters / minute, people should be able to guarantee the ability to deal with carbon monoxide in 20 minutes will be the carbon monoxide concentration decreased from 0.04% to 0.0024%.
In accordance with the Interim Provisions, enterprise standards shall be formulated, and inspection items and type inspection items shall be determined in the process of technical review. It is estimated that all other items should be done in addition to the explosion pressure (subject to 0.3MPa).
