Quick Answer
The risk of CO poisoning is greater with diesel generators due to their higher carbon monoxide emissions per hour of operation compared to gas generators. Diesel generators produce more CO due to incomplete combustion, especially in poorly maintained engines. Proper ventilation is essential when using diesel generators.
Diesel Generators: Higher CO Emissions
Diesel generators are notorious for producing high levels of carbon monoxide due to the incomplete combustion of diesel fuel. In a typical diesel engine, the air-to-fuel ratio is often less than ideal, leading to the formation of CO as a byproduct. A well-maintained diesel generator can still produce significant CO emissions, with levels ranging from 20-100 ppm (parts per million) or even higher in extreme cases.
Gas Generators: Not a Safer Alternative
While gas generators may produce lower CO emissions compared to diesel generators, they still pose a significant risk of carbon monoxide poisoning. A typical gas generator can produce CO levels between 10-50 ppm, which can quickly accumulate in enclosed spaces. It’s essential to remember that CO is a colorless, odorless gas that can be deadly in high concentrations, even at low levels over extended periods.
CO Safety Precautions: Proper Ventilation and Maintenance
To mitigate the risk of CO poisoning when using generators, it’s crucial to ensure proper ventilation and regular maintenance. Install generators outdoors, at least 20 feet away from living spaces, and consider using a CO alarm to detect potential leaks. Regularly inspect and maintain your generator, paying attention to the air filter, fuel system, and exhaust components. Additionally, always follow the manufacturer’s guidelines for usage, maintenance, and troubleshooting.
