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

10 minutes
20 minutes
30 minutes
1 hour

The correct answer is: 20 minutes

In a one-hour rated corridor partition, the doors that are part of that assembly must have a fire rating that matches or exceeds the rating of the corridor. For a one-hour rated corridor, it is essential that the door has a fire rating of at least one hour as well, ensuring adequate protection and compliance with fire safety codes. A door with a fire rating lower than the corridor rating, such as a 10-minute, 20-minute, or 30-minute rating, would not provide the required level of fire resistance and could potentially compromise the safety of the corridor in the event of a fire. Therefore, a door with a rating of one hour is necessary to maintain the integrity of the fire-resistive assembly and to offer the appropriate level of safety and security.
