ICC Commercial Building Inspector Practice Test

What is the required fire rating for a door separating a laundry chute discharge room from the remainder of the building?

1. 30 minutes

2. 45 minutes

3. 60 minutes

4. 90 minutes

The correct answer is: 45 minutes

The required fire rating for a door separating a laundry chute discharge room from the remainder of the building is indeed 45 minutes. This requirement is based on the understanding that laundry chute discharge areas can present significant fire hazards due to the accumulation of lint and other combustible materials. A door with a 45-minute fire rating serves to adequately limit the spread of fire and smoke from the discharge room into the building's other areas, providing occupants more time to evacuate and improving overall safety. Building codes typically specify fire resistance ratings for different compartments based on the potential risk associated with the materials and activities contained within them. The door’s fire rating helps ensure that the fire protection systems within the building can function effectively and that critical evacuation routes remain accessible for a sufficient duration during an emergency situation. The other options reflect longer fire ratings, which might be applicable in different contexts or to different rooms, but for laundry chute discharge areas specifically, 45 minutes is the correct and code-compliant requirement.
