If you are already carrying 100 pounds of silver cyanide, what precautions must you take if you are given papers at a dock to carry 100 cartons of battery acid?

For safety reasons, silver cyanide and battery acid are on the list of materials that cannot travel together (Refer to the "Do Not Load" table in the Maine CDL Manual.). Silver cyanide is a Division 6.1 material (poison). It cannot be loaded with acids since their mixture can release hydrocyanic acid, an extremely poisonous substance.
