Which measures are recommended to protect egress routes in large spaces?

• A. Increase occupancy pressure to evacuate faster.
• B. Install only additional red exit signs.
• C. Compartmentation, smoke control, illumination, wayfinding, and maintain clear, protected paths.
• D. Remove doors along egress to create open corridors.

Answer: (C)

Protecting egress routes in large spaces requires an integrated approach that both limits the spread of fire and guides people safely to exits. Compartmentation uses fire-resisting barriers to slow fire and smoke, giving occupants time to evacuate and preventing exits from becoming engulfed too quickly. Smoke control helps keep the area near exits as tenable as possible, reducing smoke inhalation risk and improving visibility and travel speed. Adequate illumination remains critical, especially if power is lost or during smoke events, so occupants can see their path to exits. Clear wayfinding and signage help people identify routes, destinations, and assembly points even when visibility is compromised. Maintaining clear, protected paths means exits and corridors stay unobstructed and protected by appropriate doors and barriers that preserve compartmentation and smoke control. Removing doors or relying on signs alone would not provide the necessary barriers, and increasing occupancy pressure would impede orderly evacuation rather than protect routes.
