Carbon Monoxide Safety During Hurricane Season: Essential Guidelines

Hurricane season brings severe weather conditions that can lead to power outages, prompting many to use generators and other fuel-powered devices. While these tools are invaluable during emergencies, improper use can result in carbon monoxide (CO) poisoning—a colorless, odorless gas that can be fatal.

What Is Carbon Monoxide and Why Is It Dangerous?

Carbon monoxide is produced when fuels like gasoline, wood, or charcoal burn incompletely. Exposure to CO can cause symptoms ranging from headaches and nausea to dizziness and confusion. High levels can lead to unconsciousness or death. The risk of CO poisoning increases during hurricanes due to power outages and the use of alternative power sources.

How Can I Safely Use Generators During a Hurricane?

  • Outdoor Use Only: Always operate generators outdoors in a dry area at least 20 feet away from doors, windows, and vents. (cpsc.gov)

  • Proper Ventilation: Ensure that the generator is placed in a well-ventilated area to prevent CO buildup.

  • Avoid Enclosed Spaces: Never use generators inside homes, garages, basements, or other enclosed areas, even with ventilation. (health.ny.gov)

What Are the Risks of Using Charcoal Grills and Candles Indoors?

  • Charcoal Grills: Burning charcoal indoors can produce lethal levels of CO. Do not cook on a charcoal grill in a garage, even with the garage door open. (cpsc.gov)

  • Candles: Use caution when burning candles. Use flashlights or battery-operated candles instead. If using candles, do not burn them on or near anything that can catch fire. Never leave burning candles unattended. Extinguish candles when leaving the room and before sleeping. (cpsc.gov)

How Can I Protect My Home from Carbon Monoxide During a Hurricane?

  • Install CO Alarms: Place working carbon monoxide alarms on every level of your home and outside sleeping areas. Test alarms monthly and replace batteries as needed. (cpsc.gov)

  • Inspect Appliances: After a flood, have a qualified professional inspect and replace gas control valves, electrical wiring, circuit breakers, and fuses that have been under water. (cpsc.gov)

What Should I Do if I Suspect Carbon Monoxide Poisoning?

  • Immediate Action: If you or someone else exhibits symptoms of CO poisoning, such as headache, nausea, dizziness, or confusion, get outside immediately and call 911. (cpsc.gov)

How Can I Stay Informed About Carbon Monoxide Safety?

  • Stay Updated: Follow guidance from local authorities and agencies like the U.S. Consumer Product Safety Commission (CPSC) for the latest safety tips and warnings. (cpsc.gov)

By adhering to these guidelines, you can significantly reduce the risk of carbon monoxide poisoning during hurricane season, ensuring the safety of yourself and your loved ones.
