How to define accident ponds and fire water collection ponds?
Thread Content
As the title suggests, there are already relevant discussions in the forum; the regulations or documents involved include the \"Chemical Regulations\" and Document No. 10 issued by the General Administration in October 2006. For example, the newly installed units in our factory feature so-called dry pits (for collecting flammable materials that leak in emergency situations), as well as dedicated fire-fighting water collection tanks. However, I still have some doubts regarding the concepts of accident ponds and fire water collection ponds. I would appreciate it if experts could explain their functions, definitions, and differences.

I think that’s the case, but in the event of a fire and overpressure in a distillation tower or storage tank, the material will definitely first be discharged into the accident pool. However, if fire-fighting water is used to cool or extinguish the fire at that time, won’t the wastewater on the ground also end up in the accident pool? So what’s the difference between it and a fire pond?
The accident tank is used to absorb and temporarily store liquid chemicals that leak in the event of an accident. For information on fire-fighting water collection tanks, please refer to “Cleaned wastewater””
My understanding is that for different processes, it is sometimes possible to use the same tank, or different tanks. For liquids that are not flammable or explosive but rather toxic and harmful, an accident pond is used to collect the leaked material. In the event of a fire, the leaked materials mix with the fire-fighting water and flow into the fire-fighting water collection tank. Therefore, when designing a water tank, the capacity of the tank should be determined by taking into account the maximum 24-hour rainfall amount, the fire-fighting water volume, and the capacity of the largest storage tank.
The following information is from the Internet: A fire water tank is a man-made structure used to store fire-fighting water, and it serves as an important supplement to natural water sources or municipal water supply systems. It is advisable to use the same tank for both fire-fighting water and water for living and production purposes; this not only reduces costs but also ensures that the water quality remains good. However, for shared water tanks, technical measures must be in place to ensure that fire-fighting water is not used by them, to guarantee an adequate supply of fire-fighting water, and to facilitate access to it when needed. An accident tank is a type of structure required in the wastewater treatment process; it is generally installed to handle high-concentration wastewater discharged by factories in the chemical and petrochemical industries. The reason is that when production accidents occur in these factories, large amounts of organic wastewater with high concentrations and fluctuating pH values are discharged in a short period of time. If such wastewater enters the sewage treatment system directly, it imposes a very high load on the biological treatment systems in operation, and it takes a long time to recover from the resulting effects; sometimes this can even lead to catastrophic damage. To prevent the impact of accident water on wastewater treatment systems, many wastewater treatment plants have installed accident tanks for storing such water.

Reply to 6# No Regrets: It seems that a fire water collection tank and a fire pond are not the same thing, right?
In my previous company, the accident pool and the fire suppression collection pool were built together; they were essentially one pool. I’m not sure if there are any issues with that
Yes, fire water tanks and fire water collection tanks are not the same concept; fire water collection tanks and accident tanks are the same concept!
Reply to 10# No Regrets: It’s like this! That is to say, it’s the same pool
