Question 1110 Deck Safety

The correct answer is A) carbon monoxide may enter the interior of the vessel. The exhaust pipe must be gas tight throughout its entire length to prevent carbon monoxide from entering the interior of the vessel. Carbon monoxide is an odorless, colorless, and highly toxic gas that can quickly accumulate in enclosed spaces, posing a serious health hazard to the crew. A gas-tight exhaust system ensures that all exhaust gases are safely vented overboard, rather than being able to leak into the vessel's living spaces. The other options are incorrect because they do not directly relate to the primary purpose of maintaining a gas-tight exhaust system, which is to prevent the entry of carbon monoxide.
