Do Class A equipment (other than storage tanks) require fire dikes? ? ?
Thread Content
For Class A equipment in which Class A liquids are handled (not in storage tanks), is it necessary to install a fire dike? ? ?
For example, methanol is used as a desorption liquid in the resin column to remove the substances adsorbed onto the resin; as a result, these Class A liquids end up inside the equipment (in the resin column). Is it necessary to install a fire dike around the resin column? ?
So this is the installation; there’s no need for a fire dike, but a cofferdam can be built to enclose it
The device does not require them; only the tank area needs firewalls and dikes. If you’re worried, you can build a cofferdam.
Fire dikes are only required for tank areas; for production units, a cofferdam is sufficient
It’s not necessary, but a small cofferdam can be built
Install a drainage channel to connect to the accident pool... Is that okay?
Just build a cofferdam. But I have also seen exceptions. There is a project where I saw a horizontal heat exchanger for which a fire dike was constructed.
For Class A, since the steam is denser than air, it is not suitable to have ditches or grooves. .
Sir, if there are Class A liquid storage tanks in the plant area, does such a Class A liquid storage tank require a fire dike?
