In the field of chemical production raw materials, the safety of iodine storage and transportation specifications

1. Introduction

In the field of chemical production raw materials, iodine is an important element, widely used in medicine, photography, metallurgy, analytical chemistry and other fields. However, due to the characteristics of iodine, such as volatile, toxic, corrosive and so on, there are certain safety risks in the process of storage and transportation. In order to ensure the safety of iodine in the process of production, storage and transportation, it is very important to formulate corresponding norms.

2. the nature and harm of iodine

iodine is a non-metallic element, with a high degree of reactivity. At room temperature, iodine is a solid, but easily sublimates into a purple gas. Iodine is highly toxic. Long-term exposure or inhalation of iodine vapor may cause human body poisoning, resulting in cough, dyspnea, dizziness, headache and other symptoms. In addition, iodine is also corrosive and has a corrosive effect on metals and some non-metallic materials.

3. iodine storage specifications

1. Storage facilities: Iodine should be stored in a cool, dry, well-ventilated special warehouse, avoid direct sunlight and high temperature. Anti-corrosion materials shall be laid on the warehouse floor, and ventilation equipment shall be set to ensure air circulation.
2. Storage container: Iodine should be stored in a well-sealed container, and the container material should be corrosion-resistant, such as glass or polyethylene plastic. The container shall be marked with the name, concentration and hazardous nature of the iodine.
3. Storage management: The warehouse shall be managed by special personnel, and the integrity of storage facilities and containers shall be checked regularly to ensure that there is no leakage. Any abnormality shall be handled and reported in time.

4. iodine transportation specifications

1. Transportation containers: Iodine transportation containers should meet relevant standards and have sufficient strength and sealing performance to prevent iodine leakage during transportation. The container shall be marked with the name, concentration and hazardous nature of the iodine.
2. Mode of transportation: Iodine can be transported by car, train or ship, and the appropriate mode of transportation should be selected according to the actual situation. During transportation, it should be kept stable and avoid violent vibration and collision.
3. Transport personnel: transport personnel should be professionally trained to understand the nature of iodine and transport safety knowledge, with the ability to respond to emergencies.
4. Transportation management: A detailed transportation plan should be formulated before transportation, and the transportation route and time should be clarified to ensure compliance with relevant laws, regulations and standards during transportation. During transportation, communication with relevant departments and personnel should be maintained to deal with abnormal situations in a timely manner.

5. emergency measures

1. Leakage treatment: when iodine leakage is found, measures should be taken immediately to prevent the leakage from spreading, and protective equipment should be worn for treatment. Collect the leakage in a closed container, cover the leakage area with sand or other non-combustible adsorbent, and then clean it to the designated place.
2. Poisoning treatment: if there are poisoning symptoms after exposure to or inhalation of iodine vapor, the poisoned person should be immediately moved to a ventilated place to keep the respiratory tract unobstructed. Severe cases should be promptly sent to hospital for treatment.

6. summary

In the field of chemical production raw materials, the safe storage and transportation of iodine is very important. In order to ensure the safety of iodine storage and transportation, relevant norms and standards should be strictly observed, management and training should be strengthened, and safety awareness should be improved. By taking effective measures and means to reduce the risk of iodine leakage and poisoning, to ensure production safety and personnel health.
