How should high-rise buildings address life-safety challenges?

• A. With robust egress design (stairs with proper pressurization), fire service access, compartmentation, and smoke control.
• B. By relying solely on sprinklers without egress design.
• C. By evacuating via elevators during a fire.
• D. By removing all doors to speed egress.

Answer: (A)

High-rise life safety hinges on an integrated design that keeps occupants safe during a fire while enabling firefighters to reach the scene. Robust egress design means protected stairs with proper pressurization to keep smoke out, adequate width, clear signage, and fire-rated enclosures so people can evacuate or reach refuge areas without being overwhelmed by smoke. Fire service access ensures firefighters can rapidly reach the fire floor, connect to standpipes, and operate effectively inside the building. Compartmentation uses fire barriers and fire-resistance-rated construction to slow fire and smoke spread, preserving life-safety zones and giving occupants time to escape. Smoke control systems manage where smoke travels, keeping means of egress tenable and reducing exposure for both evacuees and responders. This approach addresses the realities of high-rise fires more comprehensively than relying on sprinklers alone, using elevators for evacuation, or removing doors, all of which undermine safe egress, containment, or both.
