AI Explanation
The correct answer is B) calibrate the gas leak detectors. Span gas is a calibration gas used to check and adjust the sensitivity of gas detection equipment aboard liquefied natural gas (LNG) carriers. The gas detectors are critical safety devices that monitor for the presence of natural gas vapors, which are highly flammable. Span gas is used to ensure these detectors are functioning properly and can accurately measure gas concentrations. The other answer choices are incorrect, as they do not describe the primary purpose of span gas on LNG carriers.
