Overall, placing a portable generator on the swim platform or boarding platform is a safer option compared to other locations on the boat. By following the manufacturer's instructions and taking the necessary safety precautions, boaters can reduce the risk of carbon monoxide poisoning and enjoy the benefits of having a portable generator on their boat.

They should be placed outside the boat, in the open

It is strongly recommended that portable generators are placed outside the boat, in the open. This is because generators emit deadly carbon monoxide and need refuelling with highly flammable petrol. As such, they should never be installed in an enclosed cockpit area or engine space of a boat and must never be used on or close to the boat where exhaust fumes could enter the boat.

The Boat Safety Scheme (BSS) has issued a stark warning about the dangers of incorrect portable generator use, stating that they must be used in the open and away from the boat. The BSS has recorded 24 incidents relating to the use of generators over the past 25 years, in which 10 people have been killed and another 10 have been taken to hospital.

If you are using a portable generator, it is critical to ensure that it is placed outside the boat, in the open, and that exhaust fumes are directed away from the boat. This will help to prevent carbon monoxide poisoning, which can be deadly. Additionally, never refuel the generator on the boat; take it to the bank and ensure you are a safe distance from other boats and potential sources of ignition.

By following these safety precautions, you can help ensure that you are using your portable generator in a safe manner and reducing the risk of accidents or injuries.

They should be placed downwind, so that exhaust fumes are blown away from the boat

When placing a portable generator on a boat, it is important to consider the direction of the wind to prevent exhaust fumes from entering the boat. By placing the generator downwind, you can ensure that the exhaust fumes are blown away from the boat, reducing the risk of carbon monoxide poisoning. This is a crucial safety measure, as carbon monoxide is a colourless, odourless gas that can be deadly if inhaled.

When operating a portable generator on a boat, it is essential to prioritise safety. In addition to placing the generator downwind, it is recommended to have multiple CO detectors installed in the cabin to alert you in case of carbon monoxide presence. It is also important to refrain from running the generator overnight or when people are swimming near the stern. Always ensure that the generator is properly secured and stabilised to prevent it from falling overboard.

The placement of the portable generator will depend on the design of your boat. Some boats may have a dedicated area for generators, such as a swim platform or a boarding platform. It is crucial to follow the manufacturer's instructions and guidelines for the specific model of the portable generator you are using.

Additionally, when using a portable generator on a boat, it is important to consider the potential fire hazards associated with gasoline. Refuelling the generator should be done away from the boat, and it is crucial to follow safety protocols to prevent sparks or fuel vapour ignition. Overall, while portable generators can be used on boats, it is essential to prioritise safety and follow proper procedures to minimise risks.

They should be placed away from the boat's doors, vents, windows and hatches

When using a portable generator on a boat, it is important to take precautions to ensure safety and avoid potential hazards. One crucial precaution is to never run the generator on or near the boat's doors, vents, windows, or hatches. Here are some detailed guidelines and reasons why this precaution is essential:

• Carbon Monoxide Poisoning: Carbon monoxide (CO) is a colourless, odourless, and deadly gas produced by generators. Running a generator near openings in the boat increases the risk of CO fumes entering the cabin, posing a severe health risk to occupants. CO poisoning can lead to serious illness or even death.
• Ventilation and Airflow: Keeping the generator away from doors, vents, windows, and hatches promotes better ventilation and airflow. This helps dissipate exhaust fumes and reduces the risk of CO buildup. Proper ventilation is crucial for maintaining safe air quality inside the boat.
• Exhaust Fumes: The exhaust fumes from a generator can contain harmful pollutants and particulate matter. Inhaling these fumes can cause respiratory issues and other health problems. By keeping the generator away from openings, you minimise the chances of exhaust fumes entering the boat and compromising the air quality.
• Fire Hazards: Generators can pose a fire hazard, especially when refuelling or if there is a fuel leak. Running the generator near openings increases the risk of fumes entering the boat and potentially igniting. Keep a safe distance from the boat to minimise fire hazards.
• Noise Levels: Generators can produce significant noise levels, which can be disruptive to you and your neighbours. By placing the generator away from openings, you can reduce the noise level inside the boat, creating a more peaceful environment.
• Fuel Vapours: Fuel vapours from the generator can accumulate and pose a hazard. Keeping the generator away from doors, vents, and windows helps prevent fuel vapours from entering the boat, reducing the risk of fire or explosion.
