Is There a Safe Way to Use Generators During Winter?

April 5, 2026

Quick Answer

Yes, there are safe ways to use generators during winter, but it requires following specific guidelines to prevent carbon monoxide poisoning.

Generator Safety Precautions

When using generators during winter, it’s crucial to follow safety guidelines to prevent carbon monoxide poisoning. Make sure the generator is at least 20 feet away from any windows, doors, or vents to avoid backdrafting, which can cause carbon monoxide to enter the home. This distance should be measured from the generator’s exhaust outlet.

Ventilation and Carbon Monoxide Sensors

Proper ventilation is essential when using generators indoors or in enclosed spaces. Running a carbon monoxide detector is also a must, as it can alert you to any potential dangers. It’s recommended to use a carbon monoxide detector with a digital display that shows the current CO levels in parts per million (PPM). A level of 35 PPM or higher indicates a potential danger. You can also use a CO detector with a relay output that can trigger a warning alarm or turn off the generator.

Generator Maintenance and Storage

Regular generator maintenance is vital to ensure it operates safely and efficiently during winter. Before storing your generator for the winter, make sure to drain the fuel tank and change the oil to prevent damage from cold temperatures. Keep the generator in a well-ventilated area, away from any flammable materials, and cover it with a breathable cloth to protect it from the elements.
