You should have a Carbon Monoxide in your home.
"Know the symptoms of CO poisoning. At moderate levels, you or your family can get severe headaches, become
dizzy, mentally confused, nauseated, or faint. You can even die if these levels persist for a long time. Low levels
can cause shortness of breath, mild nausea, and mild headaches, and may have longer term effects on your health.
Since many of these symptoms are similar to those of the flu, food poisoning, or other illnesses, you may not think that CO
poisoning could be thecause." http://www.epa.gov/iedweb00/pubs/coftsht.html

Note that UL standards for CO alarms have changed. In 1992 the detector alarm if there were 15 ppm in
8 hours, today UL standards has to be 15 ppm for 30 days before it will alarm.
Todays UL listed Carbon Monoxide detector do not protect you from low levels of Carbon Monoxide. If
the detector has a display, most manufactures do not start displaying a read out until 30 ppm.
