Toolbox Talk: Carbon Monoxide Poisoning

KNOW THE RISK

Carbon monoxide (CO) is a silent killer—an odorless, colorless gas that can be deadly if inhaled. CO is produced by burning fuels and can accumulate in enclosed spaces, making it particularly dangerous in homes, garages, and other indoor areas.

Each year, at least 430 people in the U.S. lose their lives to accidental CO poisoning, and thousands more are hospitalized. Symptoms of CO poisoning include headache, dizziness, nausea, chest pain, and confusion. Without prompt action, severe poisoning can lead to loss of consciousness and death.

MITIGATE THE RISK

1. Install and Maintain CO Detectors:

• Place CO detectors in key areas of your home, such as near bedrooms and on every level of the house. Test the detectors regularly and replace the batteries twice a year. A good rule of thumb is to check batteries when you change your clocks for daylight saving time.

2. Never Use Gas Stoves or Ovens for Heating:

• Gas stoves and ovens are designed for cooking, not heating. Using them to warm your home can lead to dangerous CO buildup and put you and your family at risk.

3. Avoid Running Gasoline Engines Indoors:

• Never run vehicles, generators, or other gas-powered equipment inside or in enclosed spaces like a garage, even with the door open. Always operate generators outdoors and at least 20 feet away from windows, doors, and vents to prevent CO from entering your home.

4. Ensure Proper Ventilation:

• Regularly inspect and maintain fuel-burning appliances, chimneys, and vents to ensure they are functioning properly. Blocked or damaged vents can lead to CO accumulation in your home.

Conclusion

Carbon monoxide poisoning is entirely preventable if the right precautions are taken. The key to staying safe is awareness and preparation—installing detectors, ensuring proper ventilation, and using fuel-burning appliances responsibly.

If you suspect CO poisoning, get everyone out of the area immediately and call 911. Signs like dizziness, confusion, or a persistent headache should never be ignored. Your vigilance could save lives—don’t take risks when it comes to CO safety.
