Deadly Hazards that Arise After the Flood Waters Recede

As flood waters begin to recede and residents return home, the U.S. Consumer Product Safety Commission (CPSC) issues a warning to those affected by the floods in the Midwest. When there's a power outage, NEVER use portable generators inside the home, in an attached garage or in any other partially enclosed space. Generator exhaust contains high levels of colorless, odorless carbon monoxide (CO) which can kill in minutes.


334 people died from generator-related CO poisoning from 1999-2006. Recent data show that as use of generators has increased, so too have deaths - tragically there are about 50 per year. Many of these deaths occurred after major storms knocked out power.

The Commission provides these important life-saving tips:

Generator Safety

  • Never use a portable generator indoors - including open garages, basements, crawlspaces and sheds. Opening doors and windows or using fans will not prevent CO buildup in the home.

  • During use, keep portable generators outdoors and far away from open doors, windows and vents, so that CO does not build up indoors.

  • If you start to feel sick, dizzy or weak while using a generator, get to fresh air right away. Exposure to CO from generators can quickly lead to incapacitation and death.

  • Keep generators dry. Wait for the rain to pass before using a generator. Consumer-grade generators are not weatherproof and can pose the risk of electrocution and shock when used in wet conditions.

  • Do not connect the generator directly into your home's electrical system through a receptacle outlet - this is an extremely dangerous practice that poses a fire hazard and an electrocution hazard to utility workers and neighbors served by the same transformer.

  • If using a generator, plug individual appliances into heavy duty, outdoor-rated extension cords and plug cords into the generator.

Other Precautions

  • Check that the extension cords have a wire gauge adequate for the appliance loads and have all three prongs, including a grounding pin.

  • Keep charcoal grills outside. Never use them indoors. Burning charcoal in an enclosed space can produce lethal levels of carbon monoxide.

  • Make sure the batteries in your smoke alarm and carbon monoxide alarm are fresh. Test these alarms to make sure they are working.

  • Exercise caution when using candles. Use flashlights instead. If you must use candles, do not burn them on or near anything that can catch fire. Keep burning candles away from drafts. Never leave burning candles unattended. Extinguish candles when leaving the room.

Wet Carpets and Furniture Are Dangerous to your Health

  • Microorganisms may grow in these water-damaged products and may cause allergic reactions and infections. For more information, go to

  • Discard mattresses, wicker furniture, straw baskets and the like that have been water damaged. These cannot be recovered by washing or cleaning procedures.

  • Throw out wet room-size carpets, drapes, upholstered furniture, stuffed toys, ceiling tiles and anything that can't be picked up and cleaned by dry cleaning, steam cleaning or put in a washing machine or dryer.

  • Remove and replace wet insulation.

Avoid Electrical and Gas Hazards

  • Look for signs that your appliances have gotten wet. Discard electrical or gas appliances that have been wet because they pose electric shock and fire hazards.

  • Before using your appliances, have a professional or your gas or electric company evaluate your home and replace all gas control valves, circuit breakers, and fuses that have been under water.

Dangers to Children

  • Medicines and chemicals should be thrown away. Water may have infected the integrity of the medicine. The U.S. Department of Health and Human Services offers additional safety tips. For more information, go to

  • Young children and water don't mix. Watch children around buckets, tubs and standing water in and around the home. Even small amounts of water can be a drowning hazard.

To save yourself a bunch of heartache, headache, possibly your life and the life of your automobile, do not drive through flood waters. You could be thinking that it's not very deep, when the road could possibly be washed out. Some rescue attempts are made with positive results but sometimes there are fatalities.

People don't take into consideration the force of the rushing water and how destructive it can be. Water can get in your engine as well as your electrical system, if this takes place your vehicle is TOTALED! Just think twice before crossing flood waters.

On July 16th of this year an elderly couple drove through an underpass that had flooded even though someone was there trying to motion to them not to do it. Well, sadly they were trapped in their car and

drowned. It may not have looked deep but in actuality it was about 8 feet deep; it was just dark in the underpass. Please follow Terri's advice.

Drivers need to use extra caution when driving during a summer storm, spring thaw or prolonged rains. More than half of all flash flood fatalities are auto-related and less than one inch of water can cause a driver to lose control of his or her car. Once vehicles begin to float they move toward deep, faster-moving water where escape is even more dangerous and top-heavy vehicles may roll over. Those are the things that we should consider in "Driving in Wet Weather" -
