Sodium metabisulfite in the field of chemical production of raw materials in the safety of storage and transport specifications

1. Introduction

sodium metabisulfite as a common chemical production of raw materials, widely used in food, medicine, printing and dyeing and other fields. However, sodium metabisulfite may pose a hazard to human health and the environment if stored and transported improperly. Therefore, the purpose of this paper is to explore the safety storage and transportation specifications of sodium metabisulfite in the field of chemical production raw materials to ensure production safety and personnel health.

2. the properties and hazards of sodium metabisulfite

sodium metabisulfite is a white crystalline powder, with strong reducibility and acidity. Under high temperature, humidity, acidity and other conditions, sodium metabisulfite may decompose to produce toxic and harmful gases, such as sulfur dioxide and hydrogen sulfide, which are strongly irritating to human respiratory tract and eyes, and may cause cough, dyspnea, tears and other symptoms. In addition, sodium metabisulfite also reacts with many substances, which may cause safety accidents such as fire or explosion.

3. safety storage specifications for sodium metabisulfite

In order to ensure the storage safety of sodium metabisulfite, the following specifications should be followed:

1. The storage place should be dry, ventilated, and cool, away from fire and heat sources, and avoid direct sunlight.
2. The storage container should be well sealed to prevent moisture and impurities from entering, and avoid contact with incompatible substances such as acidic substances and oxidants.
3. During the storage process, regular inspection and maintenance should be carried out to ensure that the storage facilities are intact, and leakage and damage should be detected and dealt with in time.

4. sodium metabisulfite safety transport specification

in order to ensure the safety of sodium metabisulfite transport, the following measures should be taken:

1. transport vehicles should have the appropriate qualifications and conditions to ensure that the transport process will not cause pollution or harm to the environment.
2. The goods shall be strictly inspected and classified before transportation to ensure that the goods meet the transportation requirements and avoid mixed or wrong loading.
3. Keep running smoothly during transportation and avoid violent vibration, friction or collision to prevent damage or leakage of goods.
4. The transportation personnel shall be professionally trained to understand the nature and hazards of sodium metabisulfite and master the corresponding emergency treatment measures.

5. emergency treatment measures

In case of leakage, fire and other safety accidents during the storage and transportation of sodium metabisulfite, the following emergency treatment measures shall be taken:

1. Immediately start the emergency plan and organize personnel to evacuate and rescue.
2. Use special adsorption materials to clean up the leakage and avoid flowing into the sewer or into the environment.
3. For fire accidents, dry powder, foam and other fire extinguishing equipment should be used for fire extinguishing, and ventilation should be maintained to prevent the accumulation of toxic and harmful gases.
4. In the process of dealing with accidents, personnel shall be safe, wear corresponding protective equipment, and avoid direct contact with harmful substances.

6. conclusion

sodium metabisulfite as a common chemical production raw material, in the storage and transportation process should follow the corresponding safety standards to ensure personnel health and environmental safety. By taking reasonable storage and transportation measures and mastering effective emergency treatment methods, the safety risk of sodium metabisulfite in the production process can be reduced to ensure the smooth progress of production.
