Carbon Monoxide Risk Factors

What Are Carbon Monoxide Risk Factors?Poorly vented fuel-burning appliancesPoorly vented roomsEnclosed spacesCar running in a closed garage

Poorly vented fuel-burning appliances

Causes Of Carbon Monoxide PoisoningGas heatersFireplacesGas cookstovesGas water heatersFurnacesCharcoal grillsWood burning stovesSome of these appliances are not meant to be used as a main source of heat while others should be properly vented.If you have an open floor plan and a ventless gas heater it is likely you will be okay, but if you try to use a ventless heater in your bedroom then you could be asking for trouble.If an appliance is designed to be ventless it will be marketed as such, never use an alliance that is supposed to be vented without venting it.Wood burning stoves and fireplaces are also a leading cause of carbon monoxide exposure. If you use a fireplace it is important to make sure that your chimney is complete with no leaks and is unobstructed.A reverse air flow is a risk when using a fireplace because in this situation the air actually flows through the chimney back in to your house.
