Warning: Carbon monoxide

CO is an odorless, colorless, tasteless, and deadly gas in the exhaust produced by gasoline engines. Boats release CO through the exhaust ports of vessels that are idling, underway, or running generators. Exposure to carbon monoxide (CO) in large amounts, or even small amounts for a long duration, often results in death. When inhaled, CO rapidly replaces oxygen in tissues. Many people are surprised they can get CO poisoning when their activity is outdoors. If CO poisoning is suspected, seek immediate medical care.
