Big soda (chemical name is sodium thiosulfate, Na2S2O3) is a common chemical production raw materials, widely used in photography, printing and dyeing, medicine, environmental protection and other fields. Because of its certain chemical activity and toxicity, it is necessary to strictly abide by relevant regulations during storage and transportation to ensure safety. This article will detail the safe storage and transportation specifications of big soda.

1. safety storage specifications

1. Storage environment requirements: Big soda should be stored in a dry, cool, well-ventilated indoor environment, avoid direct sunlight and high temperature. The storage temperature should be controlled below 25 ℃, and the relative humidity should not exceed 75%.
2. Storage container requirements: Use a special sealed container to store the soda to ensure good sealing and prevent moisture and deterioration. Containers shall be clearly labeled with information such as product name, specification, production date and expiration date.
3. Storage isolation requirements: Soda should be stored separately from acidic substances, oxidants, combustibles and other chemicals to avoid chemical reactions or fire accidents. Corresponding fire-fighting facilities shall be set up in the storage area, and safety inspection shall be carried out regularly.

2. Safety Transport Specification

1. Transport Packaging Requirements: Soda should be packaged with packaging materials that meet national standards to ensure good sealing, pressure resistance and shock resistance. The packaging shall be marked with clear information such as dangerous goods mark, name, specification, production date and expiration date.
2. Requirements for transport vehicles: The vehicles for transporting soda should have the corresponding dangerous goods transportation qualification, and ensure that the vehicles are in good condition and meet the national safety standards. During transportation, the vehicle speed should be kept stable to avoid sudden braking and severe vibration.
3. Requirements for transportation personnel: The personnel who transport the big soda shall have the corresponding knowledge and skills of dangerous goods transportation, have undergone professional training and have obtained the corresponding qualification certificate. During transportation, vigilance should be maintained and measures should be taken in time when abnormal situations are found.

3. emergency treatment measures

1. skin contact: if the big soda comes into contact with the skin, you should immediately take off the contaminated clothes, rinse with a large amount of flowing water for at least 15 minutes, and seek medical treatment in time.
2. Eye contact: If the soda comes into contact with the eyes, immediately lift the eyelids, rinse thoroughly with a large amount of flowing water or normal saline for at least 15 minutes, and seek medical attention in time.
3. Inhalation: such as inhalation of soda dust or gas, should be quickly out of the field to the fresh air, keep the respiratory tract unobstructed. Such as breathing difficulties, cough and other symptoms, should be timely medical treatment.
4. Ingestion: If you eat soda by mistake, you should drink plenty of warm water immediately and seek medical attention after vomiting.

4. matters needing attention

1. it is strictly prohibited to put big soda and acidic substances, oxidants, combustibles and other chemicals mixed or mixed transport.
2. In the process of storage and transportation, the appearance and properties of the big soda should be checked regularly. If caking, discoloration, etc. are found, it should be handled in time.
3. Operators should be professionally trained to understand the nature of soda and safe operation procedures, and strictly abide by the relevant regulations.

In short, as a common raw material for chemical production, soda needs to strictly abide by relevant regulations during storage and transportation to ensure safety. Through the safety storage and transportation specifications introduced in this paper, the safety risks of soda in the storage and transportation process can be effectively reduced, and the safety of people's lives and property can be guaranteed.
