Is There a Risk of CO Accumulation in Enclosed Spaces?

CO Accumulation Risks with Generators

CO (carbon monoxide) is a colorless, odorless gas that can be deadly in enclosed spaces. Generators, like those used for power backup, can produce significant CO emissions, which increase when the engine is not properly ventilated. In areas with high ambient temperatures or humidity, CO concentration can rise more quickly.

Ventilation and CO Levels

Proper ventilation is critical to prevent CO buildup. A general rule of thumb is to ensure a minimum of 10 square feet of ventilation per 1,000 watts of generator power. For example, a 3,000-watt generator requires at least 30 square feet of ventilation. This can be achieved by positioning the generator in a well-ventilated area or using fans to increase airflow.

Preventing CO Poisoning

To minimize CO risk, ensure generators are installed and maintained according to manufacturer guidelines. Regularly inspect the exhaust system, fuel tank, and ignition for signs of damage or wear. Never run generators indoors or in enclosed spaces, and always follow the manufacturer’s recommended ventilation guidelines.
