When Should You Clean Your Storage Tank?

  • 1. Internal Inspections – When it is time for an internal inspection, your tank must be taken out of service, cleaned and prepared for an inspector to enter the storage tank.

  • 2. Changing Products – If you plan to store a different product in your tank, a full tank cleaning might be necessary. If you are switching from an unrefined product to a refined product,  like from crude oil to gasoline, you would need to remove all residue and impurities.

  • 3. Tank Issues – If your tank has a mechanical failure, you likely won’t be able to repair it in service. Depending on the problem, you would need to empty your tank, clean it and make it vapor free before you are able to make the necessary repairs. Typically, the ultimate goal of a tank cleaning is to provide a safe environment for whoever is entering the storage tank after you, whether it is an inspector or a mechanical repair company.
