Construction spec for DOT 412 tanks: corrosives, such as acids.
The construction specification DOT 412 cargo tanks are built to. The 412 replaced the MC 312. These tanks typically haul corrosives, such as acids.
Open it when you need to know what a DOT 412 is supposed to be as built. For testing and inspecting a tank already in service, go to 49 CFR 180.407.
