Precautions: 
Precautions: Wear protective clothing, goggles, respirator or respirator when handling sulphur dioxide. Workplaces should be properly  
ventilated indoors and be isolated from combustibles. Wet sulphur dioxide is highly corrosive. At room temperature, aluminum, copper, copper alloy, nickel, and ventilating can be used for anhydrous dioxide. The gas cylinder should be placed outdoors or in nickel alloy, lead, iron, cast iron, steel, molybdenum and magnesium. For wet sulfur dioxide, stainless steel, nickel-resistant alloy, polytetrafluoroethylene, polychlorotrifluoroethylene, etc. can be used. 
In the event of a fire, use misty water, foam, or sand to extinguish the fire. When the gas leaks, it should be sent to the washing tower or the fume hood connected to the washing tower by the exhaust fan.
