Carbon Monoxide and Propane Heaters

One of the main safety concerns when using propane heaters indoors is the potential emission of carbon monoxide, a dangerous gas that can lead to serious health complications and even death if not detected in time.

CO Emission by Propane Heaters

Carbon monoxide (CO) is a byproduct of burning propane. Under normal circumstances, the amount of CO produced is minimal and does not pose a significant threat. However, if the propane does not burn completely due to issues such as lack of oxygen or a malfunctioning burner, the heater may produce harmful levels of CO.

CO Detectors and Their Importance

Given the potential threat of CO poisoning, it’s important to install carbon monoxide detectors in your home. These devices can detect dangerous levels of CO in the air and sound an alarm, giving you time to evacuate the premises and take necessary action.

A CO detector should be installed on each level of your home and outside sleeping areas. The batteries should be checked regularly and replaced as per the manufacturer’s instructions.
