Dilute nitric acid should be used in strict accordance with the instructions during use. Dilute nitric acid should be stored in a cool and ventilated warehouse, away from fire and heat sources; the storage temperature should not exceed 30°C, and the relative humidity should not exceed 80%; Store separately, and avoid mixed storage; the storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.

Dilute nitric acid should be used in strict accordance with the instructions during use. Dilute nitric acid should be stored in a cool and ventilated warehouse, away from fire and heat sources; the storage temperature should not exceed 30°C, and the relative humidity should not exceed 80%; Store separately, and avoid mixed storage; the storage area should be equipped with leakage emergency treatment equipment and suitable containment materials. It is recommended that the operator wear a self-priming filter gas mask, wear rubber acid and alkali resistant clothing, and wear rubber acid and alkali resistant gloves.

Dilute nitric acid is oxidizing and corrosive, so it is very dangerous to people, and it can cause severe burns just by splashing on the skin. After the skin contacts nitric acid, it will slowly turn yellow, and then the yellowed epidermis will peel off (the contact between nitric acid and protein Afterwards, it will cause the yellow protein to react and denature). Therefore, dilute nitric acid must be used in strict accordance with the instructions during use. Dilute nitric acid should be stored in a cool and ventilated warehouse, away from fire and heat sources; the storage temperature should not exceed 30°C, and the relative humidity should not exceed 80%; Store separately, and avoid mixed storage; the storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.

Precautions for the use of dilute nitric acid:

1. Airtight operation, pay attention to ventilation;

2. The operation should be as mechanized and automated as possible;

3. Operators must undergo special training and strictly abide by the operating procedures;

4. It is recommended that the operator wear a self-priming filter gas mask, wear rubber acid and alkali resistant clothing, and wear rubber acid and alkali resistant gloves;

5. Smoking is strictly prohibited in the workplace, keep away from fire and heat sources;

6. Prevent steam from leaking into the workplace air;

7. Avoid contact with reducing agents, alkalis, alcohols, and alkali metals;

8. When handling, load and unload lightly to prevent damage to packaging and containers;

9. Equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment;

10. There may be harmful residues in the empty container;

11. When diluting or preparing a solution, the acid should be added to the water to avoid boiling and splashing.

In addition, during transportation, dilute nitric acid should be transported or stored in stainless steel or glass fiber reinforced plastic tank trucks or storage tanks, and a small amount should be packaged in acid-resistant ceramic jars or glass bottles. The net weight of each jar is 33-40kg, and it should be sealed with plaster. "Corrosive Substance" sign. For personal protection, direct skin contact is prohibited, and acid and alkali resistant gloves, masks, and other labor protection supplies should be worn during operation.
