What is the maximum allowed length for a dead end corridor?

1. 10 feet

2. 15 feet

3. 20 feet

4. 25 feet

The correct answer is: 20 feet

The maximum allowed length for a dead end corridor being 20 feet aligns with commonly accepted safety codes and guidelines established by fire safety regulations. These regulations are designed to ensure that, in the event of an emergency, occupants can quickly and effectively evacuate a building. A dead end corridor is defined as a corridor that is not directly connected to an exit, meaning it leads to a point where there is no further pathway to an exit. By limiting the length of a dead end corridor to 20 feet, safety codes help to minimize the risk of occupants becoming trapped and provide them with a more manageable distance to reach safety. This regulation reflects a balance between building design needs and the safety requirements necessary to protect the occupants. Longer dead end corridors could increase the time it would take to evacuate, heightening the risk during emergencies where every second counts. In contrast, options like 10 feet, 15 feet, and 25 feet do not align with established safety guidelines, as they either provide insufficient safety measures in emergencies or exceed reasonable limits that might complicate evacuation efforts.
