2020-03-21
liquid sulfur trioxideAlthough its status in the chemical industry is gradually rising, it cannot conceal its nature as a dangerous product. Whenliquid sulfur trioxideIn contact with water, explosive violent reaction will occur; contact with oxygen, fluorine, lead oxide, hypochlorous acid, perchloric acid, phosphorus, tetrafluoroethylene, etc. will also react violently; contact with organic materials such as wood, cotton or grass, Will catch fire; extremely hygroscopic, toxic white smoke in the air; strong corrosive to most metals when exposed to moisture.
Therefore, the operator isliquid sulfur trioxideThe production and use of the company must be specially trained, strictly abide by the operating procedures, master the operating skills, and have the relevant knowledge of sulfur trioxide emergency disposal. Closed operation to prevent leakage; Pay attention to ventilation in the workplace, and try to mechanize and automate the operating place. Eating and drinking water are prohibited in the workplace. Production, use and storage sites should also be set up leak detection alarm, the use of explosion-proof ventilation system and equipment, equipped with more than two sets of heavy protective clothing. Operators wear gas masks or self-contained helmets, rubber acid and alkali resistant clothing, rubber acid and alkali resistant gloves, and acid resistant boots.
In terms of operation safety, when opening the liquid sulfur trioxide container, make sure that the work area is well ventilated to avoid letting the released vapor enter the air in the work area; When the system leaks, stand at the upper air outlet, wear a gas mask to carry out the operation and take measures to eliminate the leakage as soon as possible. The cleaning sewage of production equipment and the flushing water of the floor inside the production workshop must be collected into the emergency pool and can only be discharged after passing the treatment.
In terms of storage security, liquid sulfur trioxideTo be stored in a cool, ventilated warehouse, avoid direct sun, should be easily (can) combustible, reducing agent, alkali, alkali metal, food chemicals stored separately. Obvious safety signs shall be set up at the storage site, the storage tank shall be sealed and covered, equipped with a breathing valve, and a metering device shall be provided. A certain space shall be reserved during storage, and the storage time shall not be too long.
