In what types of systems are fire and smoke dampers typically utilized?

• A. Plumbing and drainage systems
• B. HVAC and air distribution systems
• C. Electrical and lighting systems
• D. Structural and foundation systems

Answer: (B)

Fire and smoke dampers are essential components that are predominantly found in HVAC and air distribution systems. These dampers serve a critical function in maintaining life safety and property protection during a fire by preventing the spread of smoke and heat through ductwork and air handling systems. When a fire occurs, smoke can travel through the air distribution systems and spread throughout a building, potentially impacting multiple areas and endangering occupants. Fire and smoke dampers are installed at strategic locations within these systems to automatically close in the event of elevated temperatures or smoke, thereby restricting the movement of these hazards beyond the isolated area of the fire. The usage of fire and smoke dampers is governed by the National Fire Protection Association (NFPA) codes, which set standards for their design, installation, and maintenance. These provisions ensure that HVAC systems effectively contain smoke and fire within specific zones, allowing for safer evacuation routes and reducing damage to property. Other systems mentioned in the question, such as plumbing, electrical, and structural systems, do not utilize fire and smoke dampers because they serve different functions and do not involve the movement of air in the same manner as HVAC and air distribution systems. Therefore, the correct answer highlights where these critical safety devices are most appropriately applied.
