This staircase leads to all three floors of the reading room.
One half level down from the mezzanine entrance level leads to the Discussion Room, while on the top floor of this staircase is the photocopier / printer / scanner machine.
In case of emergency, take this staircase all the way down to the fire exit in the basement that opens out onto the Back Lane, which is the nominated fire evacuation assembly point on the right hand side of the library building.
If the fire alarm sounds in the library, leave all your posessions behind and, if leaving via this exit, head calmly down this staircase all the way to the bottom, push the fire exit door open and proceed up the short ramp and out onto the Back Lane. Do NOT go back into the Library until you have been told by the Duty Fire Officer (usually one of the Lodge staff) that it is safe to do so.
Never try to use a fire extinguisher on the fire, unless you have been fully trained in how to use a fire extinguisher.
