In which of the following areas are visual evacuation signals required to be seen?

Visual evacuation signals are specifically designed to ensure that individuals can quickly and easily identify the best route during an emergency. Hallways are critical areas for these signals because they often serve as the main thoroughfare for occupants to evacuate a building. In many building codes and standards, hallways are required to have visual evacuation signals prominently displayed to provide clear guidance in situations where visibility may be compromised due to smoke or other obstructions.

While stairwells, break rooms, and external exits may require some form of signage or indication for safety, the emphasis on visible signals during an evacuation concentrates heavily on hallways where people are likely to gather or pass through. This is because hallways can lead to multiple egress routes, making clear visual signals essential in directing the flow of people safely out of a building. Therefore, the requirement for visual evacuation signals in hallways ensures effective communication and guidance during critical moments of an emergency.
