Using a generator indoors WiLL KiLL YOU iN MINUTES.
Carbon Monoxide
Generator exhaust contains high levels of carbon monoxide (CO), a poisonous
gas 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 outdoors and far away from open 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 poisoning.
