Generator Safety

Portable generators emit deadly carbon monoxide (CO) that you can't see or smell. Never put a generator indoors (including a garage, basement or crawlspace), even if you keep doors and windows open. Using a generator outside, but too close to the home, can also be dangerous. 

Put generators at least 7.6 m (25 feet) from your home and point the exhaust away from any open windows, doors and vents to keep CO from getting in.
