Which material is often used for fire dampers due to its fire-resistant properties?

• A. Plastic
• B. Aluminum
• C. Steel
• D. Fiberglass

Answer: (C)

Steel is often used for fire dampers due to its excellent fire-resistant properties. It can withstand high temperatures and provides structural integrity in the event of a fire, helping to prevent the spread of flames and smoke through HVAC ducts. The thermal mass of steel allows it to absorb and dissipate heat effectively, contributing to its performance as a fire barrier. In many building codes and standards, including those outlined by the NFPA, steel is recognized as a suitable material for fire dampers, ensuring compliance with safety regulations. Its durability and resistance to warping or melting at elevated temperatures make it a reliable choice for installations that require a high level of fire protection.
