The safety storage and transportation specification
of NDI in the field of chemical production raw materials
1. Introduction

With the rapid development of the chemical industry, the safety problems of storage and transportation of various chemical production raw materials have become increasingly prominent. In many chemicals, NDI (diisocyanate) as an important raw material, is widely used in polyurethane, rubber, coatings and other fields. However, due to its special chemical properties, NDI has certain safety risks during storage and transportation. Therefore, it is essential to develop a set of strict NDI security storage and transportation specifications.

2. the properties and hazards of NDI

NDI is a colorless or slightly yellow transparent liquid, which is strongly irritating and corrosive. Under the conditions of high temperature, open flame and oxidant, NDI is easy to decompose and produce toxic gas, which is harmful to human body and environment. In addition, NDI is also flammable and explosive, so special care is required during storage and transportation.

3. NDI safety storage specification

1. The storage place should choose a cool, dry, well-ventilated place, away from open flames, heat sources and oxidants.
2. The storage container shall be a special container with good sealing performance to avoid decomposition caused by contact between NDI and air, moisture, etc.
3. During the storage process, the sealing performance of the container should be checked regularly, and the leakage should be handled in time.
4. The storage area shall be provided with obvious safety warning signs and equipped with corresponding fire fighting equipment.

4. NDI's safety transportation specifications

1. Transport vehicles should have corresponding qualifications and certificates, and drivers should undergo professional training and be familiar with the nature and transportation requirements of NDI.
2. During transportation, the vehicle should be kept running smoothly to avoid violent vibration and collision.
3. Special sealed tanker shall be used for the transport container to ensure that NDI will not leak during transportation.
4. During transportation, keep away from open flames, heat sources and oxidants, and avoid direct sunlight.

5. emergency treatment measures

1. In case of NDI leakage accident, the leakage source should be cut off immediately, the leakage area should be covered with sand, dry lime and other adsorption materials, and then collected into a special container.
2. If there are poisoning symptoms after contact with NDI, the patient should be immediately moved to a well-ventilated place, take off the contaminated clothing, rinse the skin with clean water, and send to the doctor for treatment in time.
3. In the event of a fire accident, fire extinguishers, sand and other fire extinguishing equipment shall be used immediately to extinguish the fire, and the police shall be called for help at the same time.

6. Training and Management

1. Conduct professional training for staff engaged in NDI storage and transportation to improve their safety awareness and operational skills.
2. Establish a sound NDI storage and transportation management system, and clarify various safety regulations and operating procedures.
3. Regularly inspect and maintain storage and transportation facilities to ensure that the equipment is in good working condition.

7. conclusion

NDI as an important raw material for chemical production, there are certain safety risks in the process of storage and transportation. In order to ensure the safety of personnel and the environment, strict safety storage and transportation regulations must be formulated, and effective emergency treatment measures must be taken. By strengthening training and management, the safety awareness and operation skills of the staff can be improved to ensure the safe and smooth storage and transportation of NDI.
