The safety of sodium iodide storage and transportation specifications

1. Introduction

Sodium iodide is a common chemical production raw material, widely used in medicine, photography, analytical chemistry and other fields. However, due to its risk, it is necessary to strictly comply with relevant regulations during storage and transportation to ensure safety. This article will detail the safe storage and transportation specifications for sodium iodide.

2. the properties and hazardous
of sodium iodide
Sodium iodide is a colorless or white crystalline powder with strong hygroscopicity. It reacts with water to produce sodium hydroxide and iodine, and with acid to produce hydrogen iodide. Sodium iodide will gradually decompose in the air to generate iodine, making the color darker. The main risk of

sodium iodide is that it reacts with water, acid and other substances to produce toxic hydrogen iodide, which is harmful to human health and the environment. In addition, sodium iodide is corrosive and can cause damage to metal containers and equipment.

3. sodium iodide storage specification

1. Storage location: sodium iodide should be stored in a dry, cool, well-ventilated place, avoid direct sunlight and high temperature.
2. Storage container: Use a well-sealed container to store sodium iodide to prevent moisture absorption and pollution.
3. Storage quantity: The storage quantity should be controlled within a safe range to avoid danger caused by excessive storage.
4. Clear identification: the storage place should have a clear identification, indicating the name, quantity and danger of sodium iodide.

4. sodium iodide transport specifications

1. Packaging requirements: sodium iodide should be double-layer packaging, the inner layer is a plastic bag or glass bottle with good sealing, and the outer layer is a strong carton or wooden box to prevent damage or leakage during transportation.
2. Mode of transportation: Sodium iodide should be transported by land or sea by car, train or ship, avoiding air transportation.
3. Transportation requirements: in the process of transportation, it should be stable, avoid violent vibration, friction and collision, and avoid mixed transportation with acids, oxidants and other substances.
4. Requirements for transportation personnel: transportation personnel should be professionally trained to understand the nature and danger of sodium iodide and master emergency treatment measures.

5. sodium iodide safe operation specification

1. operator requirements: the operator should be professionally trained, understand the nature and risk of sodium iodide, master the correct operation method and emergency treatment measures.
2. Operating environment requirements: The operating environment should be dry and well ventilated, and avoid operating in a humid or closed environment.
3. operation steps requirements: in the operation process, should be in accordance with the provisions of the steps of operation, to avoid improper operation caused by danger.
4. Requirements for protective measures: during operation, protective clothing, gloves, goggles and other protective equipment should be worn to avoid contact with skin and eyes.

6. sodium iodide emergency measures

1. skin contact: such as sodium iodide and skin contact, should immediately take off the contaminated clothing, rinse the skin with plenty of water.
2. Eye contact: If sodium iodide enters the eyes, immediately lift the eyelids and rinse the eyes with plenty of water for at least 15 minutes.
3. Inhalation: such as inhalation of sodium iodide dust or gas, should be quickly out of the field to the fresh air, keep the respiratory tract unobstructed. If breathing is difficult, seek medical attention immediately.
4. Ingestion: If you eat sodium iodide by mistake, you should drink plenty of warm water immediately and seek medical attention immediately after vomiting.

7. conclusion

In short, in order to ensure the safety of sodium iodide during production, storage and transportation, relevant regulations and safe operation requirements must be strictly observed. At the same time, the training and practice of emergency response measures should be strengthened to improve the ability to respond to emergencies. Only in this way can we ensure the safety of people's lives and property and promote the healthy development of the chemical industry.
