Question 575 Deck Safety

The correct answer is C. C is the correct answer because when releasing carbon dioxide gas (CO2), you should open the vents to allow the gas to escape. This is in accordance with the US Coast Guard regulations on handling hazardous materials. Opening the vents allows the CO2 to dissipate safely, rather than allowing it to build up in an enclosed space. The other answer choices are incorrect because A, B, and D do not properly address the safe handling of the CO2 gas. Simply doing nothing (A), using water (B), or closing the vents (D) would not be the appropriate actions to take when releasing CO2.
