Question: 1 / 400

Doors in 1-hour rated corridor partition need to have which fire rating?

10 minutes

20 minutes

30 minutes

1 hour

A door located in a 1-hour rated corridor partition must have a fire rating that matches or exceeds the rating of the partition itself to ensure effective fire-resistive protection. Since the corridor is rated for 1 hour, it is essential that the door be classified with the same fire rating of 1 hour to maintain the integrity of the barrier designed to resist fire and smoke for that duration. This consistency allows the entire assembly—walls, doors, and any penetrations—to function as intended in the event of a fire, thereby enhancing the safety of the building's occupants and providing necessary protection for escape routes.
