In the wake of the power outages caused by last week's severe thunderstorm, the Michigan Department of Community Health is reminding people of the dangers of carbon monoxide poisoning when using alternative sources of power.



Residents should be extra vigilant when they compensate for lost power. If not used safely, gas-powered generators, kerosene heaters and other non-traditional heating or power sources can cause carbon monoxide poisoning. Often, it can be safer to seek shelter with friends and family or at a community shelter.



Carbon monoxide is a tasteless, odorless, invisible gas formed when fuel is burned. It can build up to deadly levels within minutes in enclosed spaces and only can be detected with a carbon monoxide detector.



Warning signs of poisoning include flu-like symptoms without the fever: headache, nausea, vomiting, dizziness, drowsiness and confusion. Poisoning can cause comas or death.



Hundreds of people are hospitalized each year with carbon monoxide poisoning in Michigan, and 15-20 die as a result.



To prevent carbon monoxide buildup when the power is out:



n Never run a generator inside the house or garage and keep it away from windows and doors. (If theft is a concern, lock it to a tree or fence.)



n Never use charcoal or propane grills or camp stoves indoors.



n Do not use portable heaters powered by propane or kerosene indoors.



n Always turn off your vehicle in the garage.



n Place a carbon monoxide detector in the hallway outside bedrooms in all sleeping areas.
