The normal pressure diesel storage tank is not configured to transmit the pressure signal remotely to the DCS. Is it necessary? consult

There are medium storage tanks such as ethylene glycol and diesel in a certain normal pressure storage tank area of the unit.； The top of the ethylene glycol tank is equipped with a breathing valve, emergency relief hole and nitrogen sealing pressure compensation facility. The top of the diesel storage tank is only equipped with a breathing valve and does not have a relief hole or nitrogen sealing facility. ； Ethylene glycol is not managed as a hazardous chemical in the unit, but the storage tanks are equipped with more safety measures than diesel. Moreover, the tops of various storage tanks have pressure remote transmission signals that are directed to the DCS for monitoring, but the diesel storage tanks do not. ； The basic design information (designed in 2013) did not find which specification the design of these two media storage tanks follows. Can someone please explain it.
The ethylene glycol tank is heated by steam to prevent condensation and prevent overpressure of the normal pressure tank. A remote pressure transmitter is added.~~~~~~~
The specific nozzle settings are determined by the process.
Oh, okay, I feel that whether the storage tank needs these safety protection measures should be designed according to the specifications or regulations. It cannot be ignored just because the process does not seem to be available.
Gas stations now have this requirement.
Diesel is less volatile, so no.
Ethylene glycol is not volatile. In comparison, diesel is more volatile and more dangerous. Can you tell me what standards I can refer to?
