Which statement correctly differentiates a fire door from self-closing hardware?

• A. A fire door has fire resistance; self-closing hardware keeps the door open
• B. A fire door is rated for fire resistance; self-closing hardware ensures automatic closing to maintain barrier
• C. Fire door and self-closing hardware are the same
• D. Fire door is only for aesthetics

Answer: (B)

Fire doors and self-closing hardware serve different roles in maintaining a fire barrier. A fire door is rated for fire resistance, meaning it is tested as part of a door assembly to resist heat and flame for a specified period. This rating helps slow the spread of fire and provides safe egress. Self-closing hardware is a mechanism that ensures the door automatically returns to a closed position after being opened, so the barrier is not left ajar and the fire-resistance boundary is maintained.

The correct statement captures both ideas: the door’s fire-resistant rating and the automatic closing function of the hardware. It recognizes that the door itself provides fire resistance, while the closer helps keep the barrier intact by closing the door automatically.

Why the other ideas don’t fit: one option implies the closer keeps the door open, which is the opposite of its purpose; others blur the distinction by equating door and hardware or dismiss the door as merely decorative.
