NFPA 80 is a comprehensive standard that sets the minimum requirements for fire doors or smoke doors, and other protective openings in buildings. It covers various aspects of fire door installation, from material specifications to inspection protocols, ensuring that these critical components function effectively in the event of a fire.

The primary goal of NFPA 80 is to safeguard lives and property by providing a framework for the proper installation, inspection, and maintenance of fire doors. By adhering to these guidelines, architects can better equip the buildings to contain fires and prevent the spread of smoke and flames.
Requirements for Materials
NFPA 80 stipulates that fire doors and smoke doors must be constructed from materials capable of withstanding fire conditions. Steel, wood, and aluminum are commonly used since they offer unique benefits in terms of fire resistance and functionality. However, stainless steel stands out as an ideal material. Its high melting point, strength, and corrosion resistance make it a superior choice for fire door applications. Stainless steel fire door closers are particularly effective in maintaining their structural integrity under extreme heat, a key factor in preventing the spread of fire and smoke.

Basic Criteria for Fire Door Assembly Inspection with Door Closers
- Self-Closing Mechanisms: Ensure door closers or spring hinges are in place and operational, guaranteeing durable self-closing functionality.
- Operational Check for Efficiency: Assess the door closer’s performance in conjunction with the door and frame. They should provide a smooth and controlled closing action, which is critical for maintaining fire door or smoke door integrity
- Component Inspection: Confirming no missing or broken parts, with immediate repair or replacement if needed.
- Clearance Measurement: Measure door clearances to ensure they fall within NFPA 80 specified limits, typically no more than 3/4 inch at the bottom and 1/8 inch around the remaining sides.
- Latching Mechanism Verification: The door closer must exert sufficient force to engage the latch, ensuring the door stays closed and latched during a fire, which is critical for compartmentalization and preventing the spread of fire and smoke.
