This disclosure concerns a typical inspection device of the invention. In some embodiments, the inspection device functions in a storage vessel, such as a underground fuel tank, including storage vessels that comprise an explosive mixture of gases. Also, this disclosure concerns a process for inspecting the inside of the storage vessel, in some cases creating a record of the image of the inside of the storage vessel. Invention processes do not require a step of inerting the vessel. Invention devices can operate in a vessel that has not been subjected to an inerting step. |
