There's no chance the ship poses a risk of burning those grain silos. If it explodes, it won't go up like the port of Beirut, it'll just kill people on the ship and quite possibly spill large quantities of oil into the sea. The risk to the flour mill is shipping through that port would be stopped for quite some time and if there was a large burning oil slick the surrounding area could be evacuated.
