Cargo Tank - Acid-Base Incompat.
Sequential-cargo compatibility - acid tank loaded with base without proper cleaning = exothermic reaction risk.
Cleaning
Full wash + neutralise + multi-stage flush + positive-test required
Formula, assumptions, and limits
Pre-wash → wash with opposite reagent (neutralise) → fresh-water rinse → drying. Wall wipe + check pH test. MIRACL book / USCG 46 CFR 150 compatibility table.
