What are the precautions for using Pyrocatechol-3,5-Disodium sulFonate?

The formula of pyrotechnic powder is related to safety and must not be ignored. Among them, sodium pyrocatechol-3,5-disulfonate should be used with caution and keep the following items in mind.
First, this substance is chemically active and should be kept away from strong oxidants and reducing agents. If the two accidentally touch, it is very likely to cause a violent reaction, resulting in the risk of fire or explosion. For example, sulfur and strong oxidant are co-located, and it is easy to catch fire in case of heat or friction. The same is true for sodium pyrocatechol-3,5-disulfonate. Keep an eye on surrounding substances when storing and using.
Second, when taking it, it must be made with clean utensils, and the operation should be done quickly to minimize the time it is exposed to the air. Because of its reaction with some components in the air, the properties will change. Just like iron powder exposed to the air, it will rust for a long time, and its properties will not be the same as before. After taking it, it should also be sealed and stored in time to prevent it from deteriorating.
Third, operators must wear professional protective equipment, such as protective clothing, protective gloves and goggles. This object may be irritating to the skin and eyes, and if it is not protected, it may hurt the body if it is touched. If lye splashes on the skin, if it is not rinsed in time, it will burn the skin.
Fourth, the storage environment should also be suitable. A cool, dry and ventilated place should be selected, away from fire and heat sources. If the temperature and humidity are not suitable, it may cause it to decompose or deteriorate. Just as food is perishable in warm and humid places, sodium pyrocatechol-3,5-disulfonate should also be properly stored.
Fifth, the use site should have complete ventilation facilities to disperse harmful gases and prevent the risk of poisoning and explosion. Poor ventilation, gas accumulation, and a little carelessness will cause disaster.
Sixth, before and after use, check the equipment and site carefully to ensure that there is no residue. Residues may affect the next use, or bury safety hazards.
Only in this way can we ensure the safety of using sodium pyrocatechol-3,5-disulfonate and avoid disasters.
