What is the primary function of carbon monoxide detectors in a building?

• A. Detect water leaks
• B. Identify smoke presence
• C. Alert occupants to carbon monoxide levels
• D. Measure humidity levels

Answer: (C)

The primary function of carbon monoxide detectors in a building is to alert occupants to carbon monoxide levels. Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that can be extremely dangerous, leading to poisoning or even death. These detectors sense the concentration of carbon monoxide in the air and trigger an alarm when it reaches a certain threshold, providing an essential warning to occupants about the presence of this hazardous gas. Timely alerts from these devices enable individuals to evacuate the premises and seek safety, thereby preventing severe health risks associated with carbon monoxide exposure.

The other options pertain to different types of environmental monitoring and do not relate to the specific function of carbon monoxide detectors, emphasizing the critical role these devices play in ensuring occupant safety in residential and commercial buildings.
