Cracks have appeared in the tank of large oil tankers; how can accidents resulting from welding to repair these cracks be prevented?
It seems from what the poster says that a sealant needs to be used to fix the leak; safety first – never take any risks! Even if it succeeds, it’s just luck.
Empty all items from the tank, clean and replace it until it meets the requirements; after analysis confirms compliance, obtain a fire permit before proceeding with work.
In such cases, it is necessary to first drain the medium inside the tank and ensure proper ventilation, then introduce hot water into the tank. Alkali should be added along with steam, and the process should continue for a day; after that, the water in the tank must be completely drained and the tank dried out. Once this is done, a laboratory technician should be consulted to conduct an analysis for explosive gases. Only after the test comes back positive can welding work proceed. Take preventive measures during the operation, contact fire trucks for preparation, and avoid having too many people on site; always conduct a test with an open flame before starting any fire-related work. :victory:
