Portable Generator Hazards
Before refueling a portable generator, take precautions by turning it off and letting it totally cool off before adding the fuel. This will prevent possible fuel ignition. Fuel spilled on hot engine parts could ignite. A portable generator should always be used only in fire-safe locations where it will not ignite any fuel or other items. Never store a generator with fuel in the tank where gasoline vapors might reach an open flame, spark or pilot light. It should be stored in well-ventilated areas where there are no heating appliances. It should not be stored in areas that get extremely hot.
Keep the generator dry. Operate on a dry surface under an open, canopy-like structure. Dry your hands before touching the generator. Plug appliances directly into the generator or use a heavy-duty outdoor-rated extension cord. Make sure the entire extension cord is free of cuts or tears and the plug has all 3 prongs, especially a grounding pin. NEVER plug the generator into a wall outlet. This practice, known as back feeding, can cause an electrocution risk.
Never use generators indoors, including basements and enclosed areas. Keep it located outside away from doors, windows, and vents that could allow CO to come indoors. Be sure to have properly operating CO detectors. Remember, CO is colorless, odorless, tasteless, and deadly.
