How can a fire-label door be identified?

• A. It has a metal plaque
• B. It has a glass pane
• C. It is painted red
• D. It has a fire label

Answer: (D)

A fire-label door is identified by the actual fire label attached to the door or frame. This label comes from a recognized listing agency and shows the door’s fire-resistance rating, the approved door-assembly components, and often the manufacturer and date. The label provides definitive proof that the door is designed and approved to resist fire for a specified period. Decorative features like a metal plaque, glass panes, or just a red color do not prove fire resistance, so the reliable indicator is the presence of the fire label.
