The safety storage and transportation specification
of nitric acid
1. Introduction

Nitric acid is an important raw material widely used in the production of chemical products, with strong oxidation and corrosion. In order to ensure the safety of nitric acid during production, storage and transportation, it is essential to establish a set of strict specifications. This article will detail the safety storage and transportation specifications of nitric acid.

2. the physical and chemical properties of nitric acid

nitric acid is a colorless or yellowish fuming liquid with a strong pungent odor. It is easily soluble in water and can react with a variety of metals, non-metals and organic compounds. Nitric acid has strong oxidation, can cause combustion and explosion.

3. nitric acid storage specification

1. Storage site selection: nitric acid should be stored in a dry, cool, well-ventilated special warehouse, away from fire, heat and direct sunlight. The warehouse shall be equipped with safety facilities such as fire prevention, explosion-proof and lightning protection.
2. Storage container selection: A special corrosion-resistant container should be used to store nitric acid to ensure good sealing performance of the container and prevent leakage. The container should be inspected and maintained regularly to ensure safety and reliability.
3. Storage limit: The storage amount of nitric acid should be strictly controlled within a safe range to avoid safety hazards caused by excessive storage.
4. Storage identification: obvious safety identification shall be set up in the storage place, including dangerous goods identification, warning identification, etc., to remind personnel to pay attention to safety.

4. nitric acid transport specification

1. transport vehicle selection: should use special dangerous goods transport vehicles for nitric acid transport, to ensure that the vehicle has good sealing performance and anti-leakage measures.
2. Transport personnel requirements: transport personnel should be professional dangerous goods transport training, familiar with the nature of nitric acid and safe operation procedures, to ensure the safety of the transport process.
3. Transportation route planning: safe transportation routes should be selected to avoid passing through densely populated areas and sensitive environmental areas.
4. Transport identification: Transport vehicles should be equipped with obvious dangerous goods identification, and the identification should be kept clearly visible during transportation to remind other vehicles and pedestrians to pay attention to safety.

5. nitric acid leakage emergency measures

1. personnel evacuation: in the event of nitric acid leakage, should immediately evacuate nearby personnel to avoid injury.
2. Cut off the fire source: If there is a fire source near the leakage area, cut off the fire source immediately to prevent fire or explosion.
3. Take anti-leakage measures: use special equipment to recycle or treat the leaked nitric acid to avoid leakage and diffusion.
4. Take protective measures: In the process of dealing with leakage, protective measures should be taken, such as wearing protective gloves, goggles, etc., to avoid direct contact with nitric acid.
5. Clean up the site: After the leakage treatment is completed, the site should be cleaned to ensure that no potential safety hazards are left. Summary of

6.

nitric acid is an important raw material for chemical production, and its safe storage and transportation are very important. By strictly complying with the storage and transportation regulations and taking effective protective measures and emergency treatment measures, the safety risks of nitric acid in the production, storage and transportation process can be reduced to the greatest extent, and the safety of personnel and the environment can be guaranteed.
