Carbon monoxide - the Silent Killer. This gas has no odor or color and is very dangerous. Each year people suffer from illness or even death due to carbon monoxide poisoning. Never use a generator, grill, camp stove or other gasoline, propane, natural gas or charcoal burning devices inside a home, garage, or any partially enclosed area. Place the unit away from doors, windows and vents that could allow carbon monoxide to come indoors.
Avoid using a generator in a wet area - this can cause shock or electrocution.
Connect appliances to generators with grounded, heavy-duty extension cords to prevent electrical fires.
Don't fuel your generator when it is running. Turn if off and let it cool. Adding fuel to a hot motor is a fire hazard!
