Portable generators always should be placed outdoors away from attached garages and basements. Just opening a door or window for ventilation is not adequate, according to the U.S. Consumer Product Safety Commission.
The following are other suggestions for purchasing and using portable generators:
¥ Choose the right size for your individual needs. For example, 1,000 watts of power will keep a refrigerator running; another 1,000 watts will be needed for a freezer. More wattage is required to start these appliances than is needed to keep them running.
A licensed electrician or the local electric utility company would be good reference sources.
¥ Install a double-throw transfer switch for the generator to safely separate the power produced by it from utility lines coming into your residence. ¥ Keep a generator in a dry area and elevate it off the ground. Don't touch it if your hands are wet.
¥ Use heavy-duty outdoor extension cords rated for the wattage; use grounded three-prong cords only.
¥ Keep fuel a safe distance from the generator but not inside the house. Before refueling, turn the generator off and allow it to cool down.
¥ If you start to feel dizzy or weak while using a generator, get to fresh air immediately. Seek medical attention.
