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

Silver cyanide and battery acid are on the list of products that cannot travel together for safety reasons (see the "Do Not Load" table in the Handbook). Silver cyanide is a Division 6.1 material. It cannot be loaded with acids because their mixture can release such chemicals as hydrocyanic acid, which is extremely poisonous.
