Is It Safe to Use a Generator During a Snowstorm?

April 5, 2026

Quick Answer

Using a generator during a snowstorm can be hazardous, as carbon monoxide can accumulate in the air and prove deadly. Generators should be used outdoors, away from windows and doors, and at least 20 feet from any structure. This minimizes the risk of carbon monoxide poisoning.

Safety Precautions for Generator Usage

When operating a generator during a snowstorm, prioritize ventilation and clearance. Position the generator in a well-ventilated area, preferably on a level surface and at least 20 feet away from windows, doors, and any other openings that could allow carbon monoxide to enter your home. This distance ensures that the exhaust gases are diluted and dispersed before they can accumulate.

Generator Placement and Ventilation Techniques

To enhance ventilation, consider the following techniques: ensure the generator’s exhaust is pointing away from any structures or openings, and direct any snow or ice buildup away from the generator’s intake and exhaust. Regularly inspect the area around the generator for snow or ice accumulation, as this can compromise the generator’s airflow and increase carbon monoxide risk.

Additional Safety Measures

In addition to proper generator placement and ventilation, consider implementing additional safety measures: keep a working carbon monoxide detector in your home, ensure a backup power source is available for your carbon monoxide detector in the event of power outages, and follow all manufacturer instructions when operating your generator.
