Combination fire/smoke dampers must comply with NFPA 80 and which other NFPA standard?

• A. NFPA 25
• B. NFPA 105
• C. NFPA 70
• D. NFPA 54

Answer: (B)

Combination fire/smoke dampers are crucial components in fire protection and life safety systems, designed to prevent the spread of fire and smoke through ductwork in buildings. To ensure their effectiveness and compliance with safety regulations, these dampers must adhere to multiple standards. While NFPA 80 establishes the requirements for fire dampers, NFPA 105 specifically addresses smoke dampers, including the testing, installation, and maintenance practices for these devices. NFPA 105 focuses on the performance and functionality of smoke dampers in stopping the passage of smoke in structural assemblies. This delineation is essential because while NFPA 80 governs fire resistive components, NFPA 105 ensures that smoke control measures are implemented correctly in conjunction with these components. This dual compliance underscores the importance of maintaining both fire and smoke protective measures within HVAC systems to enhance overall building safety. In this context, the other standards listed do not apply to combination fire/smoke dampers in the same relevant capacity. For instance, NFPA 25 pertains to the inspection, testing, and maintenance of water-based fire protection systems; NFPA 70 covers electrical safety; and NFPA 54 is related to fuel gas code requirements. Therefore, they do not directly relate to the specific requirements
