What is the primary function of a draft measurement in a safety inspection?

The primary function of a draft measurement in a safety inspection is to check air flow dynamics. In combustion appliances, proper draft is crucial because it ensures that the combustion gases are effectively vented outside, preventing dangerous buildups of carbon monoxide and other harmful gases within the living space. A well-established draft is necessary for the safe and efficient operation of appliances such as furnaces, water heaters, and fireplaces.

By assessing air flow dynamics through draft measurements, inspectors can identify potential issues like inadequate ventilation or blockages in the flue, which can compromise safety and appliance performance. This proactive assessment helps to ensure that combustion appliances operate safely and efficiently, reducing the risk of hazardous conditions for occupants.
