Ccool adjoining horizontal and vertical surfaces before opening the door to extinguish the fire

Dkeep the door tightly closed until all the oil has been consumed by the fire

AI Explanation

The correct answer is C) Cool adjoining horizontal and vertical surfaces before opening the door to extinguish the fire. This is the correct answer because when dealing with a fire in an enclosed space, such as the HFO centrifuge room, it is crucial to first cool the surrounding surfaces before opening the door. This helps prevent the sudden rush of air and potential backdraft that could occur when the door is opened, which could worsen the fire. Cooling the surfaces also helps limit the spread of the fire to adjacent areas. The other options are incorrect because they do not adequately address the need to cool the surrounding area before attempting to extinguish the fire directly.
