Commissioning plan for the storage system of concentrated sulfuric acid system

Do concentrated sulfuric acid storage tanks need to be washed with water before their first use, or do they need to be dried after washing before they can be put into use?» ?
Friend, that’s necessary. First, it can corrode storage tanks ； Second, sulfuric acid releases a large amount of heat when it comes into contact with water, causing splashing, which is unsafe! Recommendation: Allow to air-dry after manual drying, or purge with high-pressure nitrogen.
Just clean it up by mopping it with a mop. It’s fine even with very little water. If there is no manhole for entry, it can also be rinsed with water. After flushing, the remaining water level should not exceed 3–5 centimeters.
It’s not a water wash; first, a pressure test with water is carried out to check for any leaks
