Can a path of egress travel pass through a secondary space that may be closed by doors or contain storage materials?

The correct answer is that a path of egress must remain unimpeded and accessible to ensure safe and efficient evacuation during emergencies. Egress paths should not pass through secondary spaces that could potentially be closed off by doors or obstructed by stored materials. Such obstructions could hinder or delay escape, contradicting safety regulations which are designed to provide a clear and safe route for individuals to exit a building quickly.

The primary concern is the safety of occupants, which is why codes and standards typically require that paths of egress be free of any barriers. The integrity of these paths is critical during emergencies, as any obstruction could lead to confusion, increased evacuation time, or prevent individuals from exiting safely.

Considering the other options, marking a path (as mentioned in one choice) or ensuring it has the proper width does not address the fundamental requirement for an unobstructed egress route. Even with appropriate markings or dimensions, if the path can be blocked by doors or storage materials, it cannot meet the necessary safety standards. Therefore, any configuration that allows for potential obstruction is not permissible.
