Every year, over 400 Americans die from unintentional CO poisoning, while more than 20,000 visit the emergency room, and over 4,000 are hospitalized due to CO poisoning.

Understanding Carbon Monoxide and Its Risks

CO is produced when fuels like gas, wood, coal, and oil don’t burn fully. When CO gas gets into the body, it prevents the blood from carrying oxygen, leading to the cells and tissues’ damage and death. In high concentrations, CO can kill within minutes.

CO is often referred to as the ‘silent killer’ as it’s hard to detect due to its odorless and colorless nature. People often mistake CO poisoning symptoms for a common flu as they are quite similar – headache, nausea, breathlessness, dizziness, collapse, loss of consciousness.

Sources of Carbon Monoxide

In homes, the major sources of carbon monoxide are:

1. Gas appliances like boilers, heaters, and ovens that are not maintained properly.

2. Fireplaces and chimneys with insufficient ventilation.

3. Burning charcoal indoors or in a tent.

4. Running cars in an attached garage.

5. Blocked flues and chimneys.

6. Cigarette smoke.
