  As an emergency first responder for the gas company I don’t believe there is ever a time that the fire department doesn’t call us out when someone calls them for CO. On the contrary, I am called out many times directly with people not calling 911. 95% of the time the fire department isn’t needed for the situation. If I need them to vent out the building with their gigantic fans, then I’ll call. CO detectors generally start alarming at around 35PPM CO. If the homeowner calls us immediately all I need to do is open a few windows to get a draft going and in 20 minutes the house is below 5PPM. I’d rather not tie up emergency services when they might be needed elsewhere. Just my take.

  I think you mean CO. And the answer is GTFO and call the fire department >
  
  CO2 is carbon dioxide, average people don’t have CO2 detectors in their home, usually places like fast food restaurants that use CO2 to carbonate fountain beverages have them.
  CO is carbon monoxide. If your CO detector goes off, go outside to fresh air and call emergency services. >
  
  I had to unplug my CO detector because it kept beeping, which gave me a headache, and made me feel dizzy and nauseous. >
  
  Take my toxic gasseous upvote and suffocate on it. (Bravo) >
  
  Go outside IMMEDIATELY and call your gas company. They should send someone out asap. >
  
  I don’t know if this changes in other countries or anything, but call 911 (emergency services) not your gas company.
