Know the location of the alarm signal-stations and how they operate. The Dispatcher at the Security Office will notify the Fire Department when an alarm is transmitted. When the fire alarm sounds, leave at once. Close doors behind you. Proceed to the nearest stairwell and evacuate the building.
Elevator shafts are like chimneys.
Smoke could enter the elevator shaft and asphyxiate the occupants trying to evacuate the building. If the door feels cool, open cautiously. Be braced to slam door shut if hall is full of smoke or you feel heat pressure against the door. If hall is clear, proceed to stairwell. If it is hot or smoke is seeping in do not open it.
