Question 1013 Deck General

The correct answer is B) from the open deck. The reasoning for this is that the access to a cargo pump room on a tank vessel carrying grade D liquid cargo must be from the open deck, as per the regulations. This is to ensure that the cargo pump room is physically separated from other spaces on the vessel, such as galleys, living quarters, or navigation spaces, as well as sources of vapor ignition. This separation helps to minimize the risk of fire or explosion hazards associated with the handling of the grade D liquid cargo. The other options are incorrect because they do not fully meet the regulatory requirements for the access to a cargo pump room on a tank vessel carrying grade D liquid cargo.
