Safety storage and transportation specifications
of anhydrous sodium sulfite in the field of chemical production raw materials
1. Introduction

anhydrous sodium sulfite is a common chemical raw material, widely used in many fields, such as printing and dyeing, papermaking, pharmaceuticals, etc. However, due to its special chemical properties, anhydrous sodium sulfite has certain safety risks during storage and transportation. In order to ensure its safe storage and transportation, it is essential to develop a set of standardized operating procedures.

2. the properties of anhydrous sodium sulfite

anhydrous sodium sulfite is a white crystalline powder with strong reducibility and easy oxidation. At the same time, anhydrous sodium sulfite is easily soluble in water, and the aqueous solution is alkaline. Therefore, during storage and transportation, special attention should be paid to prevent oxidation and moisture.

3. anhydrous sodium sulfite storage specifications

1. The storage place should choose a dry, cool, well-ventilated place, avoid direct sunlight and high temperature.
2. The storage container should use plastic or glass containers with good sealing performance, and avoid using metal containers.
3. During storage, the tightness of the storage container should be checked regularly to prevent moisture or oxidation of anhydrous sodium sulfite.
4. The storage area shall be provided with obvious safety signs and equipped with corresponding fire fighting equipment.

4. sodium sulfite anhydrous transportation specifications

1. Transport vehicles should have moisture, sun, rain and other functions to ensure stability during transportation.
2. During transportation, it should be kept stable and avoid violent vibration and collision to prevent packaging damage.
3. During transportation, it should be away from fire source, heat source and oxidant to prevent the oxidation reaction of anhydrous sodium sulfite.
4. transportation personnel should have the corresponding chemical transportation knowledge, understand the nature of anhydrous sodium sulfite and safe operation procedures.

5. safety operation procedures

1. in the operation of anhydrous sodium sulfite, should wear protective gloves, goggles and other personal protective equipment, to avoid direct contact.
2. Handle gently during operation to avoid dust and prevent inhalation.
3. In the event of a leak, immediately cover it with sand or other non-combustible material and collect it in a sealed container.
4. In case of contact with eyes or skin, rinse immediately with plenty of water and seek medical help.

6. Training and Education

Regular training and education should be provided to ensure that staff are aware of and master the safe storage and transport practices for anhydrous sodium sulfite. The training content should include the nature of anhydrous sodium sulfite, safe operation procedures, and the use of personal protective equipment. In addition, regular drills should be conducted to improve the ability of staff to respond to emergencies.

7. supervision and inspection

In order to ensure that the standard operating procedures are implemented, the storage and transportation process should be inspected and supervised regularly. The inspection contents shall include the environmental conditions of the storage place, the tightness of the container, the protective measures of the transport vehicle, etc. For the problems found, timely rectification should be carried out to ensure the safe storage and transportation of anhydrous sodium sulfite.

8. conclusion

anhydrous sodium sulfite as a common chemical raw material, there are certain safety risks in the process of storage and transportation. In order to ensure its safety, a set of standard operating procedures should be formulated and implemented. By strengthening staff training and education, improving safety awareness, and regular supervision and inspection, we can ensure the safe storage and transportation of anhydrous sodium sulfite and provide a stable supply of raw materials for chemical production.
