ICC Certified Fire inspector One Practice Test

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

1. 2 feet

2. 3 feet

3. 4 feet

4. 5 feet

The correct answer is: 4 feet

The maximum length allowed for a dead-end corridor is a critical factor in fire safety design as it relates to occupant egress in the event of an emergency. The correct answer indicates that, according to the International Building Code (IBC) and other fire safety regulations, a dead-end corridor should not exceed 20 feet in length in most circumstances. However, in specific cases or designs that use special features such as smoke barriers, this maximum can be expanded. When corridors exceed this length, the risk increases for occupants who may become trapped in a dead-end during a fire or emergency situation, limiting evacuation routes. By adhering to the maximum length requirement, fire safety can improve significantly, facilitating quicker and safer evacuations. The other potential answers do not align with the widely accepted codes that govern fire safety and egress design, which is a fundamental knowledge area for a fire inspector. Understanding these limits allows fire inspectors to effectively evaluate building plans and ensure that safety standards are maintained to protect occupants within the structures they inspect.
