Carbon Monoxide

"Survival After the Storm" Hurricane Preparedness Poster

Carbon monoxide, also known as CO, is called the "Invisible Killer" because it's a colorless, odorless, poisonous gas. More than 200 people in the United States die every year from accidental non-fire related CO poisoning associated with consumer products. Nearly 100 of those deaths are linked to portable generators.

Many Americans own portable generators to keep the power on after a storm. However, many people don't realize that one portable generator can produce the same amount of carbon monoxide as hundreds of cars.

Protect Your Family from Carbon Monoxide Poisoning

  • Never use portable generators inside homes or garages, even if doors and windows are open. Use generators outside only, at least 20 feet away from homes with exhaust facing away.
  • Install battery-operated CO alarms or CO alarms with battery backup on every level of the home and outside sleeping areas. Interconnected CO alarms are best; when one sounds, they all sound.
  • Know the symptoms of carbon monoxide poisoning: headache, dizziness, weakness, nausea, vomiting, sleepiness, and confusion. If you suspect CO poisoning, get outside to fresh air immediately, and then call 911.
