Ammonium hydrogen fluoride in the field of chemical production of raw materials in the safety of storage and transport specifications

1. Introduction

Ammonium hydrogen fluoride is an important inorganic chemical raw materials, widely used in glass, ceramics, metallurgy, electronics and other fields. However, due to its corrosive and toxic properties, it is necessary to strictly comply with relevant safety regulations during storage and transportation to ensure the safety of personnel and the protection of the environment. This article will detail the safe storage and transportation specifications for ammonium bifluoride.

2. the properties and hazards of ammonium bifluoride

Ammonium bifluoride is a white crystalline powder with strong irritation and corrosiveness. It has an irritating effect on the eyes, skin and respiratory tract. Inhalation of high concentrations of ammonium bifluoride gas can cause bronchitis, pneumonia and pulmonary edema. In addition, ammonium bifluoride reacts with water to form hydrofluoric acid and ammonia, both of which are toxic and corrosive.

3. ammonium bifluoride storage specification

1. The storage place should choose a dry, ventilated, and cool place to avoid direct sunlight and high temperature.

2. The storage container should be made of corrosion-resistant materials, such as polyethylene or polypropylene plastic barrels, and should have sealing performance to prevent leakage.

3. During the storage process, the container should be checked regularly and the leakage should be handled in time.

4. The storage site shall be provided with warning signs and equipped with corresponding emergency treatment equipment, such as fire extinguishers and sand.

4. of ammonium bifluoride transportation specifications

1. Before transportation, check whether the packaging is intact, and deal with or replace it in time if it is damaged.

2. During transportation, high temperature and direct sunlight should be prevented, and good ventilation should be maintained.

3. Transport vehicles shall be provided with corresponding anti-leakage measures, such as the use of sealed carriages or equipped with leakage emergency treatment equipment.

4. Avoid mixing with acidic substances, oxidants, etc. during transportation.

5. Transport personnel should be professionally trained to understand the nature and hazards of ammonium bifluoride and master the corresponding emergency treatment measures.

5. emergency treatment measures

1. skin contact: immediately take off contaminated clothing, rinse with plenty of flowing water for at least 15 minutes. Seek medical attention.

2. Eye contact: immediately lift the eyelid and rinse thoroughly with plenty of flowing water or normal saline for at least 15 minutes. Seek medical attention.

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. Seek medical attention.

4. ingestion: gargle with water and drink milk or egg white. Seek medical attention.

6. conclusion

ammonium bifluoride as an important chemical raw material, in the process of storage and transportation need to strictly abide by the relevant safety regulations, in order to ensure the safety of personnel and environmental protection. By understanding the nature and hazards of ammonium bifluoride, mastering its storage and transportation specifications, and taking corresponding emergency measures, the risk of accidents can be effectively reduced.
