For example, in the rainy season in the south, the air humidity is quite high, and if stored improperly, the chemical is easily damaged.
Second, avoid contact with oxidizing substances. The chemical properties of this compound may cause it to react violently with oxidizing agents, or even cause fire or explosion. Just like gunpowder in ancient times, it will explode when it is exposed to oxidizing substances. Therefore, when storing, it must be stored separately from oxidizing agents, and ensure that the storage area has good fire and explosion-proof facilities.
Third, take protective measures during transportation. Appropriate packaging materials should be used to ensure good sealing and prevent leakage. Transport vehicles must also be equipped with corresponding protective equipment, and drivers must be familiar with emergency treatment methods. If a leak occurs during transportation, such as the leakage of ancient toxic substances, measures must be taken quickly to evacuate the crowd and prevent the expansion of harm.
Fourth, follow relevant regulations and standards. Whether it is storage or transportation, it must be strictly implemented in accordance with relevant national and local regulations to ensure legal compliance of operations and ensure personnel safety and environmental pollution. In this way, the safety and stability of 5-amino-3- [[4 '- [ (7-amino-1-hydroxy-3-sulfonyl-2-naphthyl) azo] [1,1' -biphenyl] -4-yl] azo] -4-hydroxy-2,7-naphthalene disulfonate trisodium salt during storage and transportation can be ensured.
