Could It Be Carbon Monoxide?
Carbon monoxide poisoning can begin with symptoms that may seem ordinary. But when a generator or other fuel-burning equipment may be involved, those symptoms should be taken seriously.
Know the Warning Signs
Possible symptoms include headache, dizziness, nausea, weakness, confusion, or fainting. Severe poisoning may affect the brain and heart and can lead to loss of consciousness.
Carbon monoxide can accumulate when generators are operated inside homes, garages, basements, sheds, partly enclosed spaces, or too close to doors, windows, and ventilation openings.
What Should You Do?
Leave the area immediately and move into fresh air. Do not go back inside to search for the source.
Call emergency services if someone has fainted, is severely confused, loses consciousness, or cannot be awakened. Contact your local Poison Control center for expert guidance and seek medical evaluation when exposure is suspected.
To reduce the risk, operate generators outdoors and away from doors, windows, and vents. Make sure working carbon monoxide alarms are installed inside the home.
Get outside. Get fresh air. Get help.
