I am trying to better understand the safety risks of a 316L stainless steel storage tank with a dilute (<3 wt%) solution of Phosphoric acid at about 100F. Some quick searching and conversations with tank vendors indicated that 316L is the metallic MOC which will be least corroded by the phosphoric acid, but basic chemistry tells me that reactions with iron and nickel will still happen, resulting in production of hydrogen gas. I would like to know if there will be enough hydrogen production that the room/system would have to be designed per NFPA 2 code, but I can't seem to find any sources that will tell me reaction rates for these reactions. Wondering if there are any seasoned engineers out there who have some guidance.
