Narrative
Following the completion of an API 653 out of service tank inspection and repairs, product was found on the ground next to the tank chime during the re-filling of the tank. Subsequent inspeciton indicated the presence of a pinhole in the floor of the tank, resulting in the release. The tank was repaired by qualified personnel following API 653 and returned to service. The section of the floor containing the pinhole was removed and sent to a metallurgical lab for analysis, which indicated the cause may have been due to corrosion, but it may also have been caused by a damaged blasting hose. The report concluded that the debris adjacent to the leak site between the epoxy coating and the floor had the appearance of blasting grit, and the metal loss may have been due to corrosion , but it may have also been caused by a damaged blasting hose used to clean the floor in preparation for applying an epoxy floor coating.
