CO shutoff not stated by the manufacturer. Run it outdoors only, never in a garage or on a porch, and keep it at least 20 feet from any opening. Portable generators kill roughly 85 people a year in the US, almost always indoors.
Transcribed from the manufacturer’s published specification. Check it against the nameplate before buying.
