Rhode Island Boater Practice Test

Where are the exhaust outlets located that could cause a swimmer to get a fatal dose of carbon monoxide?

1. At the bottom of the swim steps

2. Beside the last rung of a bow ladder

3. Near an outboard engine

4. Under a swim platform

The correct answer is: Under a swim platform

The exhaust outlets located under a swim platform are particularly dangerous because this area can trap exhaust fumes, including carbon monoxide, which is a colorless and odorless gas that can accumulate quickly. When someone is in the water near the boat, the swimmer is at a higher risk of inhaling these fumes, especially if they are close to the submerged area where exhaust is expelled. The configuration of the boat’s design often directs exhaust downward and can create a hazardous situation where carbon monoxide is concentrated near the water's surface, increasing exposure risk for anyone swimming or floating nearby. While the other options indicate possible exhaust locations, they do not pose the same level of risk for swimmers. For instance, the bottom of the swim steps or near the last rung of a bow ladder may not trap or channel exhaust effectively as compared to the area under the swim platform, where stagnant water can exacerbate the situation. Being aware of these potential hazards is crucial for ensuring safety while engaging in boating activities.
