Read： 842 Time：19months ago Source：Transform the World with Simplicity

In the field of chemical production raw materials, sodium thiosulfate is a common chemical substance, which is widely used in printing and dyeing, papermaking, medicine, metallurgy and other fields. Because of its certain danger and toxicity, it is necessary to strictly abide by relevant regulations during storage and transportation to ensure safety. This paper will detail the specification for safe storage and transportation of sodium thiosulfate. Dangerous and toxic
of

1. sodium thiosulfate
sodium thiosulfate is a white crystalline powder with strong reducibility and alkalinity. Its reaction with acids, oxidants and other substances will produce toxic and harmful gases, such as hydrogen sulfide, sulfur dioxide and so on. At the same time, sodium thiosulfate is also corrosive and can cause irritation and damage to human skin and eyes.

2. sodium thiosulfate storage specifications

1. Storage environment: sodium thiosulfate should be stored in a dry, cool, well-ventilated indoor environment, avoid direct sunlight and high temperature.
2. storage container: should use plastic or glass steel material container to store sodium thiosulfate, avoid the use of metal containers, so as to avoid chemical reaction.
3. Storage identification: Clear identification shall be attached to the storage container, including chemical name, manufacturer, production date, danger and other information.
4. Storage management: A sound storage management system shall be established to record and manage the storage and use of sodium thiosulfate to ensure safety.

3. sodium thiosulfate transportation specifications

1. Transportation vehicles: Special dangerous goods transportation vehicles should be used for transportation to ensure that the vehicles meet relevant standards and requirements.
2. Transportation packaging: sodium thiosulfate should be packaged with special packaging materials, and the packaging should be tight and firm to prevent leakage and other accidents during transportation.
3. Transport identification: Clear identification shall be attached to the transport packaging, including the name of the chemical, the danger, and the precautions for transportation.
4. Transportation personnel: transportation personnel should be specially trained to understand the danger of sodium thiosulfate and transportation specifications to ensure safety during transportation.

4. sodium thiosulfate leakage treatment

in the process of storage and transportation, such as sodium thiosulfate leakage accident, should take the following measures to deal with:

1. immediately cut off the leakage source, to prevent the spread of leakage.
2. Use sand, dry lime and other adsorption materials to cover and clean up the leakage.
3. Place the cleaned waste in a special hazardous waste disposal site for treatment.
4. Ventilate the leakage area to ensure air circulation.

In conclusion, in the field of chemical production raw materials, the safe storage and transportation of sodium thiosulfate is very important. Relevant units and individuals should strictly abide by relevant specifications and standards to ensure the safety of sodium thiosulfate during storage and transportation, and prevent accidents.
