May pipe racks or pipe tunnels be installed inside the fire dike? ? Can other equipment besides pumps be placed inside the fire dike? ? Is there any legal basis for this?
Pipe racks or pipe tunnels can be installed within the fire dike, but unrelated equipment should generally not be placed there.
Sir, does that mean the relevant equipment can be placed on the fire dike? For example, can instruments or control valves be used?
Instruments certainly can. For the control valve, take a look; if you really think it’s better to place it inside, then you can consider putting it there. But I think it’s better to leave it outside generally.
Pipe racks can be installed within the fire dike; there are already many pipes laid out in the tank area, so how can they be arranged without pipe racks?
Of course, sure. Are we supposed to lay the pipes on the floor if we’re not using pipe racks? The equipment instruments are already located within the fire dike, so they can stay there; control valves are also usually installed at the base of the equipment, so that’s fine as well
Sir, I would like to ask: for pumps handling Class A liquids outside a fire dike, is it necessary to use a fire dike or a cofferdam? Where should Class A liquids that are inside the fire dike or leaking from pumps go, or how should they be collected? ? Thank you!
Pumps do not require a fire dike or a cofferdam; of course, you can build one if you wish. Pump leakage is generally not taken into account; drainage ditches should be installed within the fire dike, allowing for switching to the rainwater system as well as to accident tanks or emergency tanks.

Pipe racks can be installed inside the fire dike; there are already many pipes laid out in the tank area, so how else can they be arranged without pipe racks? Piping equipment such as instruments and control valves can be placed inside the fire dike. Equipment related to the tank can be placed inside the fire dike in close proximity. The pump needs to be placed outside the fire dike; generally, a retaining wall is required around the pump, but no fire dike is needed.
