For environmental inspections of liquid ammonia storage tanks, is it required to have a 200 m³ emergency pool?

Environmental protection officials came to inspect the liquid ammonia storage tank (with a capacity of around 10 cubic meters, which does not constitute a major hazard source) and demanded the creation of an emergency tank with a capacity of 200 cubic meters What environmental reason exactly drives such actions?
Liquid ammonia is a chemical substance commonly used in industrial production and refrigeration equipment. A 200-cubic-meter emergency tank was established to handle potential liquid ammonia leaks or other emergencies. Such emergency tanks can be used to collect and store leaked liquid ammonia, in order to prevent it from causing pollution and harm to the environment. Liquid ammonia has a pungent odor and is harmful to humans; therefore, in the event of a leak, it can pose a danger to the surrounding environment and people. The installation of an emergency tank allows for the rapid collection of liquid ammonia, reducing the spread of leaks and minimizing harm to the environment and people. Furthermore, leaks of liquid ammonia can also have a negative impact on air quality. The installation of emergency ponds can prevent leaked liquid ammonia from entering the soil and water sources, thereby reducing pollution to the ecosystem. In short, a 200-cubic-meter emergency tank is established to protect the environment and human safety in the event of leaks or other emergencies from liquid ammonia storage tanks. This can effectively control the spread of liquid ammonia, reducing harm to the environment and human health. .
In the event of a fire or liquid ammonia leak, fire-fighting or neutralizing wastewater is not **.
Emergency ponds are generally planned as part of the entire plant’s design; for liquid ammonia storage tanks, cofferdams need to be considered
Collect the spray absorption wastewater that occurs during leaks or fires; the tank volume is calculated based on the volume of the Ni storage tank
These people are extremely unprofessional; their volume calculations are incorrect – it’s ridiculous! Besides, isn’t ammonia-based disinfectant nothing but ammonia solution, which farmers use as fertilizer? As for pollution, pesticides similar to ammonia solution are simply applied directly to the fields – does that count as pollution? In China, such ridiculous things happen that even the people involved can’t explain them · ·
Only one pool is useless. After liquid ammonia leaks, ammonia gas is produced; to repair the emergency tank, one can only collect the water used for spraying and decontamination after the leak, or store water that is circulated. 200 liters is a fairly large volume of water; this figure wasn’t decided arbitrarily, but was calculated based on the concentration of ammonia that results after water is used for purification following a leak. I was in charge of the ammonia-pressure refrigeration plant; during the summer, one liquid ammonia tank exploded, and the gases released burned the corneas of the workers who were there to inspect it. The current 20-liter tank containing 20% ammonia solution has an enclosure installed to prevent any leakage from occurring; an absorption device has also been added behind the vent valve.
