5. Carbon Monoxide (CO): It is an invisible, odorless, tasteless gas that is produced when a
carbon-based fuel burns.
Never enter areas under swim platforms where exhaust outlets are located—even for a second. One or
two breaths in this area could be fatal.
Slow Speed or Idling causes carbon monoxide to accumulate in the cabin, cockpit, and rear deck. Stay 20
feet from other boats so you don't inhale its CO.
Early symptoms of CO poisoning include irritated eyes, headache, nausea, weakness, and dizziness.
