dear LCREP,

Forgive me, my question is less clear. Our engineers are planning to put a portable electric pump unit to remove residual ethanol in the tank. Distance of the tank outlet to the pump unit is only 1 meter over it. The pump unit and the electric motor is a pump used for hazardous locations. As a safety officer, I do not allow it because of the placement of the pump is within the dike that protects the tank from possible spills of ethanol. Although the use of the pump is only used for 6 hours. I mean, is there a standard that allows the placement of the pump in the dike that contains two tanks with a capacity of ethanol 5000kl? thank you very much

anidmilan,

Please read forum policies. Cross-posting in different forums is not allowed unless you refer all posters to one place. Two threads gets really confusing. Example: your first responder here thought you were discussing a fire pump.
