Carbon Monoxide (CO) is a colorless, odorless, and tasteless gas produced when fuels like natural gas, propane, wood, charcoal, or gasoline do not burn completely. Because it cannot be seen or smelled, it is often called the “silent killer.”
When inhaled, carbon monoxide enters the bloodstream and prevents red blood cells from carrying oxygen to vital organs and tissues. Even small amounts can cause symptoms such as headaches, dizziness, nausea, confusion, and fatigue. High levels of exposure can lead to loss of consciousness, brain damage, or even death.
