Stairwells are for emergency use and may be utilized for routine travel between floors, if card readers are installed inside the stairwell, on your leased floor. Please do not prop stairwell fire doors open; doing so defeats a major safety system and affects the security system. Access into the stairwells is always available. However, once inside, exit should be made on the exit floor or on the first floor. Elevators are available for unrestricted use on a continual basis, except during emergency situations.
