Carbon Monoxide(CO) Overview:

2.1 General Carbon Monoxide Information

CO cannot be seen, smelled, or tasted and can be fatal. The buildup of CO in the blood is called the carboxyhemoglobin (COHb) level and interferes with the body’s ability to supply itself with oxygen. Depending on the concentration, CO can kill in minutes. The most common sources of CO are malfunctioning gas appliances used for heating and cooking, vehicles running in an attached garage, blocked chimneys or flues, portable fuel-burning heaters, fireplaces, fuel-powered tools, and operating a grill in an enclosed space. Indications of carbon monoxide poisoning include symptoms similar to the flu, but with no fever. Other symptoms include dizziness, fatigue, weakness, headache, nausea, vomiting, sleepiness, and confusion. Everyone is susceptible to the danger of CO, but experts agree that unborn babies, small children, pregnant women, senior citizens, and people with heart or respiratory problems are at the highest risk for serious injury or death. Every year a qualified technician should inspect and clean your heating system, vents, chimney, and flues.

2.2 Symptoms of Carbon Monoxide Poisoning
The following symptoms are related to CARBON MONOXIDE POISONING and should be discussed with ALL members of the household:

2.2.1 Mild Exposure:
Slight headache, nausea, vomiting, fatigue(often described as “Flu-like” symptoms).

2.2.2 Medium Exposure:
Severe throbbing headache, drowsiness, confusion, fast heart rate.

2.2.3 Extreme Exposure:
Unconsciousness, convulsion, cardiorespiratory failure, death.

2.2.4 Many cases of reported CARBON MONOXIDE POISONING indicate that while victims are aware they are not well, they become so disoriented they are unable to save themselves by either exiting the building or calling for assistance. Young children and household pets are typically the first affected.

The above levels of exposure related to healthy adults. Levels differ for those at high risk. Exposure to high levels of carbon monoxide can be fatal or cause permanent damage and disabilities. Many cases of reported carbon monoxide poisoning indicate that while victims are aware they are not well, they become so disoriented they are unable to save themselves by either exiting the building or calling for assistance. Also, young children and household pets may be the first affected. Familiarization with the effects of each level is important.

2.3 More detailed information on conditions which can result in transient CO situations, such as:

1. Excessive spillage or reverse venting of fuel burning appliances caused by:
   i) Outdoor ambient conditions such as wind direction and/or velocity, including high gusts of wind; heavy air in the vent pipes (cold/humid air with extended periods between cycles).
   ii) Negative pressure differential resulting from the use of exhaust fans.
   iii) Simultaneous operation of several fuel burning appliances competing for limited internal air.
   iv) Vent pipe connection vibrating loose from clothes dryers, furnaces, or water heaters. v) Obstructions in or unconventional vent pipe designs which amplify the above situations. 2) Extended operation of unvented fuel-burning devices (range, oven, fireplace, etc.). 3) Temperature inversions which can trap exhaust gasses near the ground. 4) Car idling in an open or closed attached garage, or near a home.
