There are two stairwells in the building, both of which are pressurized when the building is in alarm or when manually activated at the smoke control panel. Both stairwells have vestibules to access each floor, and contains a Class 1 standpipe. Each vestibule contains a fire phone jack, or in the case of the 3rd and 8th floors, a full fire phone handset. Floor 5 through 10 are locked and require a magnetic key card to access the vestibule from the stairwell. Key cards are on each set of keys in the key box in the Fire Control Room. Stairwell locks can be manually over-ridden by means of a switch in the Fire Control Room. Stair 1 is located in the north end of the center core and contains the floor isolation valves for the sprinkler system. The valves are located between 10 and 12 feet off the floor in the stairwell vestibule, depending which floor you are on. Stair 1 allows access to the roof by means of a roof hatch that is accessed by a wall ladder. The key to the lock on the hatch is on each set of keys in the key box in the Fire Control Room. Stair 2 is located in the south end of the center core and is the best choice to use for roof access. The stairwell continues all the way up to the roof to allow access to the penthouse. If the door to the roof is locked, it can be opened using the master key on each set of keys in the key box in the Fire Control Room. This stairwell's standpipe continues all the way up to the roof level and there is an additional fireman's phone jack at the roof level. |

On the 3rd and 8th floors of each stairwell, a full fireman phone handset is present instead of a handset jack.
