Carbon monoxide (CO) is a colorless, odorless, and poisonous gas. The primary sources of CO in residential settings are fuel-burning appliances, such as furnaces, water heaters, stoves, and fireplaces. These appliances, when functioning correctly and properly ventilated, exhaust CO outside the home. Problems arise when these systems malfunction or are improperly ventilated, allowing CO to accumulate indoors.
Ensuring the safe operation of fuel-burning appliances is paramount for protecting occupants from CO exposure. Regular maintenance, including inspection of exhaust systems, is essential. Additionally, the installation and proper functioning of CO detectors are vital safety measures. These devices provide an early warning of elevated CO levels, enabling occupants to evacuate and address the source of the leak.
