Read： 789 Time：9months ago Source：Transform the World with Simplicity

Sodium hydride is a common chemical reagent, which is widely used in laboratory and industrial production. However, there are some special precautions to be taken when using sodium hydride to ensure safe and correct use. The following describes the correct use of sodium hydride and precautions:

1. Check the packaging
Before using sodium hydride, first check whether the packaging is intact to avoid damage or leakage during transportation or storage. If any damage to the packaging is found, stop using it immediately and seek assistance from the supplier.

2. Wearing Personal Protective Equipment
When handling sodium hydride, you must wear appropriate personal protective equipment, including protective eyewear, protective clothing, and chemical gloves. These equipment can effectively protect the skin and eyes, and avoid damage caused by contact with sodium hydride.

3. Avoid contact with water and air
Sodium hydride in contact with water and air will produce a violent chemical reaction, the release of toxic hydrogen and alkaline solution. Therefore, special care should be taken in the handling of sodium hydride to avoid contact with water and air. If splashing occurs, rinse immediately with plenty of water and seek medical attention.

4. Comply with the operating procedures When using sodium hydride
, you must strictly abide by the operating procedures and operate in the correct way to avoid accidents. When preparing sodium hydride solution, it should be diluted according to the experimental requirements and relevant standards to avoid excessive use.

5. storage precautions
sodium hydride is flammable and explosive goods, storage should be away from fire and oxidant, to avoid fire or explosion. Keep the packaging intact during storage and store separately from acids to prevent chemical reactions.

In summary, the correct use of sodium hydride is very important, and any incorrect operation may lead to serious consequences. Therefore, it is important to strictly follow operating instructions when using sodium hydride, wear personal protective equipment, and strictly observe storage precautions. Only in this way can we ensure the safe use of sodium hydride and avoid accidents.
