What type of inspection is typically performed on dampers?

• A. Visual inspection only
• B. Functional and visual inspections
• C. Only pressure testing
• D. Thermal imaging inspections

Answer: (B)

The most accurate approach to inspecting dampers involves both functional and visual inspections. A visual inspection allows technicians to identify any obvious physical damages, blockages, or signs of wear that may hinder the damper's operation. This can include checking for rust, corrosion, or mechanical failures that are visible. In addition, functional inspections are crucial in verifying that the damper operates as intended. During this part of the inspection, the damper is typically tested to ensure it opens and closes correctly in response to fire alarm systems or HVAC control signals. This dual approach helps ensure that dampers can function as part of a fire protection system, playing a key role in preventing smoke and fire from spreading through the ventilation system. Other inspection types, like pressure testing or thermal imaging, may play specific roles in different contexts, but they do not comprehensively cover the essential functions that both functional and visual inspections provide for dampers. Thus, the combination of functional and visual inspections is recognized as the standard practice for maintaining the efficacy of fire and smoke dampers.
