What details should be noted for exhaust gas treatment in different situations

Exhaust gas treatment in different situations should pay attention to the following details:
1, inert gas treatment:
inert gas although not dangerous, but a large number of inert gas concentration, will reduce the surrounding oxygen content, so that people suffocate.
(1) are discharged in appropriate outdoor areas.
(2) If the cylinder or instrument is indoors, an exhaust catheter can be connected to direct it to the outdoor slow discharge

.
2, gas treatment:
(1) will stick to the container valve or use equipment on the powder, petroleum, grease and flammable substances, the bottom is removed clean, can be gas treatment.
(2) it is strictly prohibited to assist gas and flammable gas in the same place near its vicinity, in order to prevent the occurrence of explosion accidents.
(3) there should be no source of fire, no combustion and no explosives around the treatment of the gas.
3, the treatment of flammable gases:
(1) combustible gas emissions, if the emissions are large, should be as far as possible to choose a place with fewer people, pay attention to the surrounding fire, and with the corresponding fire extinguishers, sand and water.
(2) discharge flammable gases from cylinders, the staff should stand on the side of the air supply port to prevent gas from spewing out injury.
(3) when using combustion method treatment, should be installed pressure relief valve, control the speed of combustible gas, as far as possible so that the gas slowly released, so that it is fully burned in the combustion device.
4. Treatment of toxic gases:
(1) When dealing with toxic gases, staff members must wear gas masks, gloves and other protective gear and other protective equipment unrelated to the treatment of personnel, prohibited from entering the gas treatment area.
absorbents and adsorbents used in toxic gas treatment should be ensured to be effective.
