3-Chloro-4- (dimethylamino) benzodiazepine hexafluorophosphate is a chemical substance, and its storage and transportation are very important. If there is a slight mistake, it will cause a disaster. The following details need to be noted.
Storage precautions
1. ** Environmental conditions **: This substance should be stored in a cool, dry and well-ventilated place. Because it is very sensitive to temperature and humidity, high temperature and humidity can easily cause decomposition and deterioration. If placed in a place where the temperature is too high, it will be like dry firewood in contact with fire, the reactivity will increase greatly, or it will cause danger. Therefore, the warehouse temperature should be strictly controlled, generally not exceeding 30 ° C, and the relative humidity should not exceed 75%.
2. ** Keep away from contraindications **: It needs to be stored separately from flammable materials, combustibles, reducing agents, etc., and must not be mixed. This is because of its active chemical properties. Contact with the above substances, such as ice and fire, can easily cause violent reactions, such as combustion and explosion. Like reducing agents, it will redox with diazonium salts, releasing a lot of energy, with unimaginable consequences.
3. ** Packaging Requirements **: Packaging must be sealed to prevent moisture and leakage. Good packaging, such as a strong fortress, can block the intrusion of external factors. Packaging materials that meet relevant standards, such as glass bottles, plastic bottles, etc., should be used, and the name of the substance, hazardous characteristics and other information should be clearly marked on the outside of the package.
Transportation Precautions
1. ** Transportation Qualification **: The transporter must have professional qualifications and rich experience, and be familiar with the transportation rules and emergency treatment methods of such dangerous chemicals. Unlicensed transportation, such as sailing without a rudder, is dangerous.
2. ** Vehicle Selection **: Select suitable transportation vehicles to ensure that the vehicle has good ventilation, sun protection, rain protection and other facilities. At the same time, the vehicle should be equipped with corresponding fire protection equipment and leakage emergency treatment equipment to prepare for emergencies.
3. ** Transportation Process **: During transportation, ensure that the container does not leak, collapse, fall, or damage. Driving should be stable, avoid violent operations such as sudden braking and sharp turns, just like smooth sailing, to prevent substances from causing danger due to collision and friction. In addition, follow the prescribed route and do not stop near densely populated areas or important facilities.
