1% 2C2-diene-4-iridium isothiocyanate (9Ci) is a special chemical substance. During storage and transportation, many key precautions must be paid attention to.
First storage conditions. Due to its nature or particularity, it is necessary to find a cool, dry and well-ventilated place. This environment can effectively avoid chemical reactions caused by moisture and high temperature to prevent material deterioration. If stored in a humid place, the substance may react with water vapor, causing its chemical structure to change and damage its original characteristics. High temperature environment may also trigger its decomposition or other adverse reactions, so be sure to control the temperature within an appropriate range.
Second is the packaging requirement. Packaging materials must have good sealing and corrosion resistance. Sealing can prevent substances from coming into contact with outside air and water vapor, reducing the risk of oxidation or hydrolysis. Corrosion resistance is due to the active chemical nature of the substance, ordinary packaging materials may be corroded, causing substances to leak and cause safety accidents.
When transporting, it should be strictly implemented in accordance with chemical transportation specifications. Transportation vehicles need to be equipped with necessary safety equipment and emergency treatment tools to prevent emergencies during transportation. Drivers and escorts must also be professionally trained to be familiar with the characteristics of the substance and emergency disposal methods. In case of leakage, effective measures can be taken quickly to avoid the expansion of hazards.
The labeling of the substance should not be ignored. Key information such as its name, nature, and hazard category should be clearly marked on the outside of the package. In this way, both storage personnel and transportation personnel can see at a glance, and take corresponding protection and operation according to their characteristics to ensure the safety of storage and transportation.

1% 2C2-diene-4-iridium isothiocyanate (9Ci) This chemical substance has the following effects on the environment and human health:
In terms of the environment, if the substance accidentally enters the natural environment, it has a specific chemical structure and properties, or it may cause harm to the aquatic ecosystem. Aquatic organisms are sensitive to chemicals, and their presence may interfere with the normal physiological functions of aquatic organisms, affecting reproduction, growth and survival. For example, it will hinder the normal respiration and metabolism of fish, change the structure of microbial communities in water, and break the ecological balance, which in turn will cause a chain reaction to the entire aquatic ecological chain. In the soil environment, it may change the physical and chemical properties of the soil, affect the activity of soil microorganisms, hinder the absorption of nutrients by plants, cause the growth of vegetation to be inhibited, and affect the regional ecological landscape and ecological service functions.
It is potentially toxic to human health. Inhalation through the respiratory tract may irritate the respiratory mucosa, causing symptoms such as cough, asthma, breathing difficulties, etc. Long-term exposure or heavy inhalation, or damage the lung tissue, increasing the risk of respiratory diseases, such as chronic obstructive pulmonary disease, lung cancer, etc. If exposed to the skin, it may cause allergic reactions to the skin, redness, swelling, itching, rash, etc. In severe cases, it can cause skin ulceration and infection. If eaten inadvertently, it can damage the digestive system, causing nausea, vomiting, abdominal pain, diarrhea and other symptoms, and may even damage important organs such as the liver and kidneys, affecting their normal functions. In addition, given that it contains elements such as iridium, in the long run, it may have potential carcinogenicity, teratogenicity and mutagenicity, threatening the stability of human genetic material and adversely affecting the health of future generations.
