Question:

If you are carrying 100 pounds of silver cyanide and you are given papers at the shipper's dock to carry 100 cartons of battery acid as well,

Answer: inform someone and do not load the battery acid.

Explanation
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 cannot be loaded with acids or other corrosive materials because their mixture can release hydrocyanic acid, which is extremely poisonous.
