The other night at 3:00 in the morning my smoke detector/CO2 alarm started beeping. Why doesn’t this every happen during the day, that will always be one of life’s great mysteries, but what do you do then?
Well, if there is no smoke, it’s probably the CO2 part of your alarm being activated. The first thing to do is open all of your windows, then shut off all gas appliances. Check everyone in the home for nausea (CO2 poisoning). If anyone is sick (headache, nausea, confusion, drowsiness) then get to a neighbors and call 911. If no one is sick, then simply call the Fire Department for a CO2 check.
