What is the recommended safety measure when running a generator on board?

• A. Run the generator in a cabin for warmth.
• B. Open a hatch briefly if it becomes warm.
• C. Never operate any electrical appliances on board.
• D. Proper ventilation and never using a generator in an enclosed space or asleep area.

Answer: (D)

The essential safety principle is to prevent carbon monoxide buildup by ensuring proper ventilation and keeping the generator out of enclosed or sleeping areas. Generators exhaust carbon monoxide, a colorless, odorless gas that can incapacitate or kill you in minutes. Running the generator in a cabin or a space where people sleep can trap CO and create a deadly situation, and simply opening a hatch briefly does not reliably prevent that risk. The safest approach is to place and operate the generator outside the boat in a well-ventilated area, away from doors, hatches, and vents that could pull exhaust back inside. Have a carbon monoxide detector on board and follow additional safety practices such as turning the generator off before refueling and keeping it dry and stable.
