Dangerous levels of carbon monoxide – a colorless and odorless gas – can be produced from improperly ventilated furnaces, plugged or cracked chimneys, water heaters, fireplaces, stove and tail pipes. Symptoms of carbon monoxide poisoning are flu-like and may include headache, dizziness, fatigue and vomiting.
If you suspect carbon monoxide poisoning:
- Call 911 immediately.
- Open the windows.
- Get yourself or the victim to fresh air.
