6-Cyanogen-1,2,3,4-tetrahydroisoquinoline is a dangerous chemical, and there are many points to be paid attention to in storage and transportation.
When storing, first, it should be placed in a cool and well-ventilated warehouse. Because of its certain chemical activity, high temperature or poor ventilation can easily cause dangerous reactions. Second, it is necessary to keep away from fire and heat sources. This chemical may cause combustion or even explosion in case of open flames and hot topics, so fire and heat sources must be kept away. Third, it should be stored separately from oxidants and food chemicals, and should not be mixed. Because of its active chemical nature, contact with oxidants may cause violent reactions, endangering safety. Fourth, the warehouse needs to be equipped with suitable materials for containing leaks. If there is a leak, it can be collected and treated in time to avoid the spread of pollution.
When transporting, first of all, the transport vehicle should be equipped with the corresponding variety and quantity of fire equipment and leakage emergency treatment equipment. In order to prevent accidents during transportation, it can be responded to in time. Secondly, it is best to transport in the morning and evening in summer. The temperature is high in summer, the chemical is more unstable at high temperatures, and the temperature in the morning and evening is relatively low, which can reduce the risk of transportation. Furthermore, during transportation, it is necessary to ensure that the container does not leak, collapse, fall, or damage. If there is a problem with the packaging, it is easy to cause chemical leakage and cause safety accidents. Finally, it is strictly forbidden to mix and mix with oxidants, edible chemicals, etc. To prevent danger caused by interaction during transportation.
