Which of the following tests is included in a combustion appliance safety inspection?

The carbon monoxide test is a crucial part of a combustion appliance safety inspection because it directly addresses the safety of appliances that burn fuel, such as gas, oil, or coal. Carbon monoxide is a colorless, odorless gas that is highly toxic and can pose significant health risks if not properly managed. During a safety inspection, professionals measure the levels of carbon monoxide emitted by combustion appliances to ensure they are operating safely and within acceptable limits. This helps to identify potential leaks or malfunctions that could lead to dangerous build-up of this gas in living spaces, thereby protecting the health and safety of occupants.

While air quality assessments, temperature analyses, and moisture level checks can be important in assessing overall indoor environmental conditions and appliance efficiency, they do not specifically focus on the immediate safety hazards associated with combustion appliances as the carbon monoxide test does.
