Carbon monoxide is called the silent killer because people do not know it is in the air. The gas has no color, no taste and no smell. It does not cause burning eyes. And it does not cause people to cough. Yet, carbon monoxide gas is very deadly . It steals the body's ability to use oxygen. Carbon monoxide makes it difficult for the blood to carry oxygen to body tissues . It does this by linking with the blood. When the gas links with the blood, the blood is no longer able to carry oxygen to the tissues that need it. Damage to the body can begin very quickly from large amounts of carbon monoxide.

The room may appear to be turning around. The person may have trouble thinking clearly. People develop serious headache as the amount of the gas continues to enter their blood. They will begin to feel very tired and sleepy. They may have terrible stomachache. Doctors say carbon monoxide influences people differently. For example a small child will experience health problems or die much sooner than an adult. The general health of the person or his or her age can also be important.
