What is a common method to test for the effectiveness of smoke dampers?

• A. Temperature logging
• B. Pressure testing
• C. Smoke testing
• D. Visual inspection

Answer: (C)

Smoke testing is recognized as a common and effective method for evaluating the performance of smoke dampers. This procedure involves introducing a visible smoke source into the ductwork or area around the smoke damper. Observing the damper's response to the smoke is crucial; the damper should remain closed and prevent any smoke from passing through if it is functioning correctly. This testing method directly examines how well the damper contains smoke, ensuring that it performs its critical function during a fire event. Temperature logging, pressure testing, and visual inspection are important methods in their own rights for various aspects of HVAC system maintenance and fire safety. However, they do not specifically assess the functional capability of smoke dampers in the context of smoke containment as effectively as smoke testing does. Thus, smoke testing stands out as the most relevant method for this particular purpose.
