Carbon monoxide detection is the process of identifying the presence of carbon monoxide (CO) gas in the environment. CO is a colorless, odorless gas produced by burning fossil fuels, and it can be harmful or even fatal in high concentrations. Detection is typically achieved using carbon monoxide detectors, which are devices designed to alert occupants when CO levels become dangerous. These detectors work by sensing the concentration of CO in the air and sounding an alarm when it exceeds a certain threshold. It is important to install these devices in homes and buildings, especially near sleeping areas, to ensure safety and prevent carbon monoxide poisoning. Regular maintenance and testing of detectors are also essential for effective monitoring.
