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, 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 windows, doors, and vents. These
openings can pull in generator exhaust.
Even when you use a generator correctly, CO may leak into the home. ALWAYS use a
battery-powered or battery-backup CO alarm in the home.
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 poison.
