1. May a drainage ditch be installed beside a Class A liquid storage tank? ? ? Urgent! Urgent! Urgent! ! ! Are there regulations stating that it is not allowed? 2. What should be done in the event of a leak in a Class A liquid storage tank? What to do about leaked Class A liquids? ?
How big are such storage tanks? You must have cofferdams!
It shouldn’t be possible; I’m not aware of the specific regulations. But safety and environmental inspections will definitely point it out. Such storage tanks should be equipped with cofferdams and specialized collection systems.
There needs to be a cofferdam; with a cofferdam, there will be no problem of drainage ditches on the sides
Sir, should drainage ditches be installed inside the cofferdam? How should any leaks of Class A liquids or rainwater be collected? ? Where to take it after collecting? ? Should an accident pond be installed outside the fire dike? ? A hero? ?

Does your tank belong to Category A or Category B? Category A refers to liquefied hydrocarbons; in the event of a leak, there should be gas alarms in the tank area, as well as sprinklers for diluting the liquid using water, which is then directed into the accident containment tank.
It’s not possible to refer to the standards; I’ll give a general description: Rainwater collection ditches can be installed inside the cofferdam, usually on the inner side of the cofferdam walls. These ditches have a certain slope leading to collection wells, and water seals as well as systems for separating clean and dirty water are in place, with the clean water being directed to the rainwater drainage network and the dirty water going to the emergency tank. Generally speaking, properly designed items come with detailed drawings.
