DANGER
Carbon monoxide. Using a generator indoors CAN KILL YOU IN MINUTES. 
Generator exhaust contains carbon monoxide (CO). This is a poison you cannot 
see or smell. If you can smell the generator exhaust, you are breathing CO. But 
even if you cannot smell the exhaust, you could be breathing CO.
► NEVER use a generator inside homes, buildings, garages, crawlspaces, or 
other partly enclosed areas. Deadly levels of carbon monoxide can build up in 
these areas. Using a fan or opening windows and doors does NOT supply 
enough fresh air.
► ONLY use a generator outside, and far away from homes, buildings, windows, 
doors, and vents. Windows, doors, and vents can pull in generator exhaust.
► Point the engine exhaust away from homes, buildings, windows, doors, and 
vents. Also, point the engine exhaust away from combustible materials.
► Even when you use a generator correctly, CO may leak into the home or build-
ing. ALWAYS use a battery-powered or battery-backup CO alarm in the home or 
building.
► If you start to feel sick, dizzy, or weak after the generator has been running, 
move to fresh air RIGHT AWAY. See a doctor. You could have carbon monoxide 
poisoning.
