Packaging is also the key. Packaging materials need to have good sealing and corrosion resistance to ensure that chemicals do not leak during storage and transportation. Warning signs should be clearly marked on the outside of the package, such as "highly toxic" "careful" to remind relevant personnel to handle with caution.
When transporting, transportation companies and personnel with professional qualifications should be selected. Transportation vehicles need to be equipped with complete emergency treatment equipment, such as fire extinguishers, leakage emergency treatment tools, etc. During driving, it is also necessary to maintain stability to avoid bumps and collisions to prevent package damage and lead to chemical leakage.
Personnel protection should also not be ignored. Personnel exposed to this chemical must wear professional protective equipment, such as protective clothing, protective gloves, gas masks, etc., to prevent skin contact and inhalation. And before and after operation, hands should be strictly washed to prevent poisoning.
Only by paying full attention to the above matters can we ensure the safety of 2% 2C3% 2C5% 2C6-tetrabromoterephthalonitrile during storage and transportation to avoid accidents.
