Technically you can't extinguish lithium and other burning metals with water, they burn so hot they cause the H2O hydrogen and oxygen to disassociate and things get worse. Same for titanium and aluminium once they get to ignition temperature. Titanium is even worse because it reduces in nitrogen at a lower temperature than it reduces in oxygen. All they would have been doing is keeping the area shrouded/suppressed with spray to prevent noxious fumes until it burnt itself out, it's a bit stiff if you're a fish in a nearby creek!
