Afilled with water
Bgas freed
Cinerted
Dall of the above as necessary
AI Explanation
The correct answer is D) all of the above as necessary. When emergency welding repairs need to be made to the upper area of a fuel tank, the tank and/or adjacent compartments may need to be filled with water, gas freed, and inerted, as necessary. This is to ensure the safe performance of hot work and to prevent the risk of fire or explosion. Filling the tank with water helps to cool and deoxygenate the area, gas freeing removes any flammable vapors, and inerting the space with an inert gas like nitrogen further reduces the risk of ignition. Taking all of these precautions, as needed, is critical to safely conduct emergency hot work on or near fuel tanks.
