What are the precautions for the storage and transportation of benzenesulfonic acid, 2-amino-5-nitro-, and monosodium salts?

Saltpeter, di-hydroxy-5-nitro-monoclinic crystals, there are many things to pay attention to during storage and transportation.
First, saltpeter is highly oxidizing, and it must not be stored with flammable things. Such as charcoal, sulfur and other flammable things, if they meet saltpeter, if they are not careful, they may cause a violent reaction, causing fire or even explosion. Therefore, it is necessary to store saltpeter in an independent, cool and well-ventilated place, away from fire and heat sources, in case the temperature rises and causes changes in its chemical properties.
Second, when transporting, be sure to ensure that the saltpeter packaging is intact. If the package is damaged, saltpeter may leak, not only or cause its chemical activity to be affected, but also the leaked saltpeter may react with surrounding substances, endangering transportation safety. Packaging materials are also selected to resist collision, friction and have good sealing performance, so that saltpeter can be stable during transportation.
Third, humidity has a great impact on the storage and transportation of saltpeter. Saltpeter is easy to deliquescence. If the ambient humidity is too high, saltpeter absorbs water or causes it to agglomerate, which affects its quality and use. The storage place should be kept dry, and the transportation tool should also have the function of moisture prevention. Desiccant can be placed in the storage and transportation container to maintain the dry internal environment.
Fourth, personnel must be cautious in operation. Whether it is handling during storage or loading and unloading during transportation, operators should be familiar with the characteristics of saltpeter and operate strictly according to the standard procedures. Do not load and unload brutally, so as to avoid the instability of saltpeter due to collision and excessive vibration. At the same time, operators should be equipped with necessary protective equipment, such as protective gloves, goggles, etc., to prevent saltpeter from coming into contact with the human body and causing harm to people.
