Never use a portable generator inside a home, garage, shed or other partially enclosed space, even if doors and windows are open.
Use portable generators outside only, far away from the home. Keep the generator away from openings to the home, including doors, windows and vents.
Read the label on the generator and the owner's manual, and follow the instructions.
Install CO alarms with battery backup in the home outside each sleeping area.
