Which of the following indicates a door is fire-rated?

• A. It has a smoke seal
• B. It is made of solid wood
• C. It has a fire label
• D. It has a decorative trim

Answer: (C)

Fire-rated doors carry a label from an approved testing agency that states the door’s rating and listing. That label is the definitive proof that the door has been tested for fire resistance and approved for use in fire-rated assemblies. A smoke seal might be present on many doors, but it does not by itself prove the door is fire-rated. A solid wood door or decorative trim offer no guarantee of a fire-resistance rating. If the fire label isn’t present, you should not assume the door is fire-rated.
