6. When survival adit indoor concentration of O2,CO and COto fulfill the requirements of human breath,O2 concentration is 18.5%,CO concentration is less than 24 ppm ,CO2 concentration is less tan 1%of the security,it is advisable to remove the self-rescuer.

7. Under the condition of the damaged wind pressure, temperature control valve in the TCV - 1, 2, 3, 4, is always at least one in full open position. When survival adit indoor temperature, humidity, CO concentration CO2 concentrations within the scope of security, according to actual situation to reduce the number of members of temperature control valve TCV - 1, 2, 3, 4.
