PGMA Updates Standards to Reduce Exposure to Carbon Monoxide

The change aims to combat carbon monoxide poisoning associated with portable generators.

The Portable Generator Manufacturers’ Association (PGMA) has introduced an updated safety and performance standard, ANSI/PGMA G300-2023, which intends to reduce the risk of carbon monoxide (CO) poisoning associated with portable generator misuse. 

According to a recent release, this revised standard mandates CO shut-off technology for portable generators to prevent injuries and fatalities due to CO accumulation in enclosed areas. The G300-2023 standard lowers the CO shut-off thresholds, addressing potential misuse in spaces like homes, garages and other enclosed areas. 

“Our ultimate goal is to reduce carbon monoxide injuries and deaths by preventing misuse of portable generators,” PGMA Executive Director Susan Orenga said in a statement. “We are proud that 99 percent of all member products are manufactured to G300-2018, and members will be working quickly to adhere to G300-2023.”

The standard—which covers all portable generators up to 15 kW, including those powered by natural gas—mitigates CO dangers by automatically shutting down the generators when high levels of CO are detected. This feature not only enhances safety but also guides consumers on the proper outdoor locations for generator operation.

Generators manufactured after January 1, 2025, must comply with the new G300-2023 standard. The PGMA, formed in 2009, includes major North American portable generator manufacturers and is dedicated to promoting safe generator use through standards development and public education, such as its Take It Outside campaign.
