The Portable Generator Manufacturers’ Association (PGMA) has introduced a new safety and performance standard, the G300 Safety and Performance standard (ANSI/PGMA G300-2023), to address the dangers of carbon monoxide poisoning due to generator misuse. The standard includes CO-shut off technology and has received approval from the American National Standards Institute (ANSI).
The CO-shut off technology included in the G300-2023 standard is designed to reduce the risk of injury from generator misuse in enclosed spaces. The technology is based on carbon monoxide sensing and has been shown to significantly reduce deaths related to generators operating indoors where CO can accumulate. The G300-2023 standard has modified the existing shut off thresholds to further address injuries associated with generator misuse. The standard will apply to all portable generators 15 kW or smaller, including inverters, open frame, construction generators, and generators fueled by natural gas.
