In this comprehensive guide, we’ll explore the risks associated with carbon monoxide exposure and provide you with 10 key warning signs to help you keep your family safe.

The Invisible Threat: Understanding Carbon Monoxide

Carbon monoxide is an odorless, colorless, and tasteless gas that can be deadly when inhaled in high concentrations. It is produced by the incomplete combustion of fossil fuels, such as natural gas, propane, oil, wood, and charcoal.

When fuel-burning appliances malfunction or are not properly ventilated, CO can accumulate in enclosed spaces, leading to carbon monoxide poisoning.

Common sources of carbon monoxide in homes include:

• Furnaces and boilers
• Gas stoves and ovens
• Fireplaces and chimneys
• Water heaters
• Portable generators and fuel-powered tools

When inhaled, carbon monoxide binds to the hemoglobin in red blood cells, reducing the blood’s ability to carry oxygen to vital organs.

This can lead to various symptoms, ranging from mild to severe, depending on the level and duration of CO exposure.
