Every year, more than 400 people die in the U.S. from accidental carbon monoxide (CO) poisoning. CO is found in fumes produced by furnaces, portable generators, stoves, lanterns, and gas ranges, or by burning charcoal and wood. CO from these sources can build up in enclosed or partially enclosed spaces. People and animals in these spaces can be poisoned and can die from breathing CO.

The most common symptoms of CO poisoning are headache, dizziness, weakness, nausea, vomiting, chest pain, and confusion. People who are sleeping or who have been drinking alcohol can die from CO poisoning before ever having symptoms.

•  Never use a gas range or oven to heat a home.

•  Never leave the motor running in a vehicle parked in an enclosed or partially enclosed space, such as a garage.

•  Never run a motor vehicle, generator, pressure washer, or any gasoline-powered engine outside an open window, door, or vent where exhaust can vent into an enclosed area, or inside a basement, garage, or other enclosed structure, even if the doors or windows are open, unless the equipment is professionally installed and vented.

•  Keep vents and flues free of debris, especially if winds are high. Flying debris can block ventilation lines.

•  Never use a charcoal grill, hibachi, lantern, or portable camping stove inside a home, tent, or camper.

•  If conditions are too hot or too cold, seek shelter with friends or at a community shelter.

•  Install a CO alarm in your home and change the batteries often (just as you do with a smoke detector).

If you smell gas . . .

Escaping or uncontrolled natural gas may start on fire when it comes in contact with a spark or flame. If you smell gas, leave immediately. Don’t touch anything that could spark. Call your gas company or 911 from a safe distance. Do not re-enter the area until you have been advised that it is safe, warns MidAmerican Energy.
