Combustion Gases
Combustion gases are created by burning material and can quickly accumulate in indoor air.  
Sources include gas-burning appliances, kerosene heaters, wood stoves, oil or coal furnaces,
fireplaces, and even candles or incense. The most familiar combustion gas is carbon monoxide,
however other such as nitrogen dioxide, sulfur dioxide, and others are also created.  The public has
over recent years become aware of carbon monoxide poisoning. Many people have placed carbon
monoxide detectors in their homes. These detectors are not 100% reliable and health problems may
emerge at levels below the equipment's sensitivity.

Symptoms of combustion gas exposure include dizziness, headaches, poor concentration and
memory, nausea, fatigue, fast heart rate, irritation of the eyes, nose, and throat, wheezing, asthma,
persistent cough, and others.  When carbon monoxide increases to high levels, unconsciousness
occurs succeeded by death.  Many families die yearly from carbon monoxide poisoning, but more still
are chronically exposed to non-lethal amounts of combustion gases which interfere with their health.

Our inspections include measurements of carbon monoxide in your home and identification of
potential sources of combustion gases.  Our consultations outline changes which can eliminate or
reduce your risk of exposure.
