Which action best improves egress safety through blast-prone areas?

• A. Blast-resistant route design.
• B. Removing all alarms.
• C. Increasing vehicle traffic near exits.
• D. Reducing staff training.

Answer: (A)

The main idea is that keeping people safe as they escape through blast-prone areas relies on making the escape routes themselves capable of withstanding blast effects. Blast-resistant route design is the best choice because it directly protects the path occupants use, helping maintain a clear, usable egress even under overpressure and fragmentation. This approach includes reinforcing walls and doors along the route, using blast-rated glazing where needed, adding shielding or barriers to limit debris, and selecting routes that minimize exposure to the blast source while providing redundancy so other exits are available if one path is compromised. By preserving the integrity and function of the egress path, it reduces blockage, collapse risk, and injuries, enabling a quicker, safer evacuation. In contrast, removing alarms eliminates critical warning and guidance, increasing confusion; increasing vehicle traffic near exits worsens congestion; and reducing staff training leaves people unprepared to respond effectively.
