The deadliest moments of a hurricane often come after the wind stops. The U.S. Consumer Product Safety Commission (CPSC) has issued repeated warnings documenting the four post-storm hazards that kill Americans every year — and carbon monoxide from portable generators is the most dangerous of all. CPSC estimates approximately 85 to 100 Americans die each year from generator-related CO poisoning, with spikes following every major storm. Additional post-storm hazards include fires from candles and alternative heating, gas leaks from damaged appliances and connectors, and electrocution from downed power lines and flooded electrical panels.
The Four Deadly Post-Storm Hazards
1. Carbon Monoxide from Generators
Never operate a portable generator indoors, in a garage, basement, or covered porch. At least 20 feet from the house, exhaust pointing away from all windows and doors. CO from a single generator can kill within minutes and gives no warning.
2. Fire from Candles and Alternative Heating
Candles placed near flammable decorations and hurricane supplies are a leading cause of storm-related fires. Never use candles or fuel-burning lanterns indoors — use battery-powered lights. Never use a gas oven or charcoal grill to heat your home.
3. Gas Leaks from Damaged Appliances
Hurricanes can shift gas appliance connectors and damage gas lines. If you smell gas after a storm, leave the home immediately, leave the door open, do not operate any electrical switches, and call your gas company from outside.
4. Electrocution from Downed Lines and Flooded Equipment
Never touch a downed power line or approach a flooded electrical panel. Standing water can conduct electricity from flooded outlets, appliances, or downed lines. Assume all downed lines are live.
Prepare Now
- Test smoke and CO alarms before storm season. Replace batteries annually.
- Stock battery-powered or hand-crank flashlights and lanterns.
- Review generator safety rules with your household before you need to use one.
- Know where your gas shutoff is and how to use it.
