A odorless, colorless gas produced by combustion, carbon monoxide can be deadly. Use a grill only in an open, well-ventilated area, never inside the house, and keep it away from combustible materials. The exhaust fumes from gasoline-powered generators are another source of carbon monoxide poisoning. Never use a generator in an enclosed area such as a basement or garage. Make sure the area is well-ventilated, dry and preferably covered.
Generators also pose electrical hazards.
Do not connect the generator to your home's electrical system. Instead, connect appliances directly to the generator with properly sized polarized extension cords. Do not overload the generator or the cords, and place the cords where no one will trip over them. Before refueling, let the engine cool for at least two minutes to prevent fires. Store extra fuel in a safe, dry area.
