What is the impact of a malfunctioning emergency exit during a drill or incident?

• A. It has no impact on safety.
• B. It speeds evacuation due to crowding elsewhere.
• C. It hinders rapid evacuation and requires immediate repair or alternative routing.
• D. It only affects personnel in the immediate area.

Answer: (C)

When emergency exits can’t be used, the flow of people evacuating is created from a fixed network of routes. An exit that doesn’t function removes a portion of that network’s capacity, forcing everyone to funnel through fewer safe routes. That makes the remaining exits work harder, often leading to longer travel distances, crowding, and slower clearance of people from the area. The safest response in a drill or real incident is to repair the malfunctioning exit as quickly as possible or to implement an alternative routing plan—directing occupants to other usable exits, providing clear temporary signage, and possibly assigning staff to manage movement—to keep evacuation as rapid as possible.

In contrast, assuming no impact ignores the real effect of a compromised exit on overall safety. Expecting crowding elsewhere to automatically speed things up is misleading—the bottleneck at the remaining exits generally slows everyone. And the issue isn’t limited to those nearest the problem; it can affect anyone who would have used that exit, broadening the impact across the facility.
