What should be paid attention to when storing and transporting 3-amino-2,6-dimethylpyridine?
3-Amino-2,6-dimethylpyridine is also a chemical substance. When storing and transporting, pay attention to many matters.
First words storage, this substance should be placed in a cool, dry and well-ventilated place. Because the cool environment can prevent its chemical properties from changing due to excessive temperature, the dry state can avoid its reaction caused by moisture, and good ventilation can disperse harmful gases that may accumulate. And it needs to be kept away from fires and heat sources, because the substance may be flammable, and it is easy to brew in case of open flames and hot topics. In addition, it should be stored separately from oxidants, acids, etc., due to contact with it, or severe chemical reaction, resulting in safety accidents.
As for transportation, there are also many important requirements. Transportation vehicles must ensure that they are in good condition and have corresponding fire and explosion-proof devices. During transportation, they should be protected from exposure to the sun, rain, and high temperature. When loading and unloading, the operator should be light and light, and it is strictly forbidden to drop and heavy pressure to avoid material leakage due to package damage. If the material leaks, emergency measures should be taken quickly to evacuate the surrounding personnel, isolate the leaked pollution area, and select suitable materials for containment and handling according to its characteristics. Transport personnel should also be familiar with the dangerous characteristics of the substance and emergency treatment methods, so that they can properly respond to emergencies and ensure the safety of transportation.
