Stairwells
There are five (5) stairwells located throughout 600 Mass Ave. For your own safety and that of your co-workers and visitors please become familiar with all stairwell locations on your floor for rapid egress in the event of emergency.
For your protection, the stairwells are locked from the stairway side. Please keep all stairwell doors closed to maintain the calibrated balance of our building air control and temperature system and avoid potential security and fire protection issues. Please be advised that in the event of a fire alarm, all stairwell doors are designed to unlock automatically.
