What should be paid attention to when storing and transporting 2-bromo-5-chloro-1,3-difluorobenzene?
2-% nitrile-5-aldehyde-1,3-divinylbenzene is a commonly used chemical substance. During storage and transportation, many points need to be paid attention to.
It is active and easy to react with other substances. When storing, it should be placed in a cool and well-ventilated place, away from fire and heat sources. Because of its flammability, in case of open flame or hot topic, there is a risk of combustion and explosion. The temperature of the warehouse must be strictly controlled, not too high, to prevent the change of material properties, generally it should be maintained in a specific low temperature range.
Furthermore, this substance is quite sensitive to air and humidity. Make sure that the storage container is tightly closed to prevent air and moisture from invading. Once exposed to air and moisture, or cause deterioration, or reduce the quality, affecting the subsequent use effect.
During transportation, do not slack off. It is necessary to choose suitable transportation tools to ensure that the container is stable and avoid collisions and bumps. Because it is a dangerous chemical, transportation personnel should be familiar with emergency treatment methods. If there is a leak during transportation, do not panic, and deal with it quickly according to the established procedures. Evacuate the surrounding population first, set up warning signs, and then use appropriate methods to collect and clean up the leak to prevent it from spreading and causing greater harm to the environment.
In addition, whether it is storage or transportation, related operations should strictly follow national regulations and industry standards. Storage sites and transportation vehicles must be equipped with complete fire equipment and emergency rescue equipment for emergencies. Operators also need to be professionally trained to be familiar with the properties and operating specifications of the substance, so as to ensure the safety of 2-% nitrile-5-aldehyde-1,3-divinylbenzene during storage and transportation.
What are the effects of 2-bromo-5-chloro-1,3-difluorobenzene on the environment and humans?
2-% chloro-5-fluoro-1,3-divinylbenzene, its impact on the environment and the human body cannot be ignored.
This substance is in the environment, and the first to bear the brunt is a disaster to the aquatic ecosystem. If it is accidentally released into the water body, fish and other aquatic organisms may be poisoned by it. Because of its stable chemical properties, it is difficult to degrade in water, and it is easy to cause damage to biological enrichment. Aquatic organisms accidentally eat plankton containing this substance, and toxins gradually accumulate in the body, or cause physiological disorders, reproduction is blocked, and even populations wither. And this substance also has the risk of residues in the soil. If it penetrates into the soil, it can affect the activity of soil microorganisms, thereby disturbing the ecological balance of the soil, and also hinder the growth and development of plant roots, causing plant growth retardation and lower yield and quality.
As for the human body, the harm should not be underestimated. Inhaled through the respiratory tract, this substance can irritate the mucosa of the respiratory tract, causing cough, asthma, shortness of breath, etc. Long-term exposure, or damage the function of the lungs, increases the risk of lung diseases. If exposed to the skin, it can cause skin allergies, itching, redness and swelling, and even be absorbed through the skin, enter the blood circulation, and involve the whole body. The harm of accidental ingestion is even worse, which can cause gastrointestinal discomfort, nausea, vomiting, abdominal pain, and diarrhea. In severe cases, it may be life-threatening. Long-term exposure to this substance may also induce genetic mutations and increase the risk of cancer, especially lung cancer and bladder cancer.
Therefore, for 2% chloro-5-fluoro-1,3-divinylbenzene, careful protection should be taken, and its production, use and discharge should be strictly controlled to protect the environment and human safety.
