Question 779 Deck General

The correct answer is C) The cargo may be gauged by automatic float type devices. This is correct because the carriage of anhydrous ammonia in bulk is governed by the International Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk (IBC Code). The IBC Code allows the use of automatic float type gauging devices for the carriage of anhydrous ammonia, as this cargo is not flammable and does not require special precautions for flammable gas detection. The other options are incorrect because: A) Aluminum, copper, and zinc are not allowed in valve parts in contact with anhydrous ammonia due to potential corrosion issues; B) An IMO Certificate is not required, as the carriage is authorized under the IBC Code; and D) A flammable gas detection system is not required for the carriage of non-flammable anhydrous ammonia.
