Question 372 Deck General

The correct answer is B) 2 minutes. The discharge of the required quantity of carbon dioxide into any "tight" space on cargo vessels must be completed within 2 minutes, as per the regulations set by the US Coast Guard. This time period is specified to ensure the rapid and effective distribution of the carbon dioxide throughout the enclosed space, which is critical for fire suppression and the protection of the vessel and its crew. The other answer choices are incorrect because 1 minute is too short a time period, while 4 and 6 minutes are longer than the required 2-minute discharge time.
