The safety of sodium benzoate storage and transportation specifications

1. Introduction

Sodium benzoate is an important chemical raw material, widely used in food, medicine, chemical and other fields. Due to its corrosive and toxic properties, it is necessary to strictly comply with relevant regulations during storage and transportation to ensure personnel safety and environmental protection. This article will introduce the safe storage and transportation specifications of sodium benzoate in detail.

2. the nature of sodium benzoate

sodium benzoate is white particles or crystalline powder, odorless or microstrip benzoin smell, taste sweet, astringent. Soluble in water, soluble in ethanol, insoluble in ether, chloroform, benzene and carbon disulfide and other organic solvents. Its aqueous solution is alkaline and corrosive to metals.

3. sodium benzoate safety storage specification

1. storage place should be dry, well ventilated, avoid direct sunlight.
2. Storage containers shall be well sealed to prevent leakage.
3. The storage area should be away from fire and heat sources, and smoking and open flames are prohibited.
4. Should be stored separately from oxidants, acids and edible chemicals, and avoid mixed storage.
5. Equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment.

4. sodium benzoate transport specification

1. transport vehicles should be qualified for the transport of dangerous goods, drivers and escorts need to be professionally trained and qualified.
2. During transportation, ensure that the container is well sealed to prevent leakage.
3. During transportation, avoid high temperature, open flame and electrostatic spark, and keep away from fire source and heat source.
4. It is strictly prohibited to mix with oxidants, acids, edible chemicals, etc.
5. During transportation, it shall be protected from sun exposure, rain and high temperature.

5. leakage emergency treatment

1. Quickly evacuate the personnel from the leakage pollution area to the safety area, isolate them and strictly restrict access.
2. It is suggested that emergency personnel should wear self-contained positive pressure breathing apparatus and anti-acid and alkali working clothes, and do not directly contact with leakage.
3. A small amount of leakage: avoid dust, with a clean shovel collected in a dry, clean, covered container. Large spills: covered with plastic sheeting and canvas to reduce scattering, then collected, recycled or transported to waste disposal sites.

6. protective measures

1 respiratory system protection: when the concentration in the air exceeds the standard, you should wear a self-priming filter dust mask. Wear an air respirator if necessary.
2. Eye protection: wear chemical safety glasses.
3. Body protection: wear anti-acid and alkali overalls.
4. Hand protection: wear rubber gloves.
5. Other protection: Smoking, eating and drinking are prohibited at the work site. After work, shower and change clothes. Maintain good hygiene habits.

7. first aid measures

1. Skin contact: immediately remove contaminated clothing, rinse with plenty of flowing water for at least 15 minutes, and seek medical attention.
2. Eye contact: immediately lift the eyelid, rinse thoroughly with plenty of flowing water or normal saline for at least 15 minutes, and seek medical advice.
3. Inhalation: Quickly leave the site to fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately and seek medical attention.
4. ingestion: gargle with water, drink milk or egg white, and seek medical attention.

8. conclusion

sodium benzoate as an important raw material for chemical production, its safe storage and transportation is very important. Through strict compliance with relevant regulations, personnel safety and environmental protection can be effectively guaranteed, and the healthy development of the chemical industry can be promoted.
