What is an essential factor in maintaining vented dampers?

• A. They must always be powered
• B. They require routine cleaning
• C. They should remain open at all times
• D. They must be checked for obstructions

Answer: (B)

Routine cleaning is crucial in maintaining vented dampers because these components can accumulate dust, debris, and other contaminants that might hinder their operation. Proper airflow is essential for the ventilation system's efficiency and safety, and any obstruction can prevent dampers from opening and closing as intended. Regular cleaning helps ensure that these dampers function properly during normal operation and in emergency situations, such as during a fire, which could otherwise lead to ineffective smoke control and increase the risk of fire spreading due to blocked pathways. While factors such as routine checks for obstructions are also important, and keeping the dampers powered may be necessary for their operation, the proactive approach of regular cleaning addresses potential issues before they occur, thus preserving the integrity and safety of the HVAC system.
