Builders are exploring new ways to
make office workers feel safe. Options include protective steel plating on the building's facade, blastproof escape routes, safety floors where people can wait out a fire, and laser-based
devices that can identify dangerous chemicals.
1. Refuge areas: Located at 15-floor intervals, these concrete-reinforced bunkers have high heat resistance.
2. Bombproof elevator shafts: These will enable firefighters to quickly reach the problem area.
3. Pressurized stairwells: Located within the building's concrete core, these fireproof stairwells connect to the refuge areas and provide a smoke-free escape route.
4. Emergency command center: The building's security facility is located on a floor above the lobby where it is less vulnerable to car bombs.
5. Concrete core: A central vertical column of concrete suppots the building's weight and provides a fireproof shell for emergency stairs and elevators.
Concrete-encased steel columns: Concrete's heat resistance will delay the melting of structural columns during a fire.
Exterior steel plating: Covering a building's concrete facade with steel plates will help deflect a high-speed impact.
Wireless fire alarms: Sensors on each floor are connected independently to the emergency command center.
Poison and explosives detectors: A laser spectrometer continuously analyzes air samples and alerts security staff to chemical dangers.
Sprinklers: High-tech sprinklers emit a mist that extinguishes fires without damaging sensitive equipment.
