What questions should be paid attention to in different situations of exhaust gas treatment
What issues should be paid attention to in the treatment of exhaust gases in different situations?
1. Treatment of inert gases:
Although inert gases are not dangerous, the accumulation of a large amount of inert gases can reduce the surrounding oxygen content, leading to suffocation.
(1) Discharge in an appropriate outdoor location.
(2) If the steel cylinder or instrument is indoors, an exhaust duct can be connected to slowly discharge it outdoors.
2. Treatment of combustion gas:
(1) Powder, petroleum, grease, and flammable substances adhered to container valves or utensils must be thoroughly removed before proceeding with the treatment of auxiliary gas.
(2) It is strictly prohibited to handle combustion gases and combustible gases in the same area or nearby to prevent explosion accidents.
(3) There should be no sources of ignition, combustibles, or explosives around the area where combustion supporting gases are being processed.
3. Handling of combustible gases:
(1) If the emission of combustible gases is large, it is advisable to choose a place with fewer people as much as possible, pay attention to prohibiting fires in the surrounding area, and prepare corresponding fire extinguishers, sand, and water.
(2) When discharging combustible gases from steel cylinders, workers should stand on the side of the gas outlet to prevent gas spraying and injuring people.
(3) When using the combustion method for treatment, a pressure reducing valve should be installed to control the speed of combustible gas and try to slowly release the gas, so that it can be fully burned in the combustion device.
4. Treatment of toxic gases:
(1) When handling toxic gases, workers must wear protective equipment such as gas masks and gloves. Personnel unrelated to the handling work are prohibited from entering the toxic gas processing area.
(2) The absorbents and adsorbents used in the treatment of toxic gases should ensure their effectiveness before use.
