What materials are commonly used for fire dampers?

• A. Wood or plastic
• B. Galvanized steel or stainless steel
• C. Fiberglass or aluminum
• D. Copper or brass

Answer: (B)

Fire dampers are critical components in HVAC systems designed to prevent the spread of fire and smoke through ductwork. The materials used in their construction must meet strict safety standards to withstand high temperatures and provide reliable performance during a fire scenario. Galvanized steel and stainless steel are commonly used materials for fire dampers due to their durability, fire-resistant properties, and structural integrity. Galvanized steel offers corrosion resistance, which is important in maintaining the functionality of the damper over time, while stainless steel is known for its high heat resistance and strength, making it suitable for high-temperature environments. These materials ensure that the dampers will function as intended during emergencies, thereby enhancing overall fire safety in buildings. In contrast, options such as wood or plastic are generally unsuitable for fire dampers because they can combust easily and do not provide the necessary fire resistance. Materials like fiberglass or aluminum, while useful in other applications, lack the structural capabilities required to safely contain and redirect fire and smoke. Copper or brass also do not provide the necessary fire resistance and may not be compliant with the relevant fire safety codes. Therefore, galvanized steel and stainless steel remain the optimal choices for ensuring fire dampers perform effectively in emergency situations.
