1. Basic Concepts of Stairwell Pressurization

John Klote, P.E., Fellow Life Member, John Klote Fire and Smoke Consulting, Leesburg, VA 

The intent of pressurized stairwells is to provide tenable conditions in stairwells for the evacuation or relocation of occupants during a fire. Pressurized stairwells are designed to operate between a minimum and maximum pressure difference. Stack effect and building complexity are major challenges to achieving acceptable pressurization.

 Pressurization systems consist of single and multiple injection systems, compartmentalization, stairwells with vestibules, stairwells with fire floor exhaust and compensated stairwells. The extent of a design analysis depends on the extent of the challenges that have to be dealt with and design analysis can range from very simple calculations to sophisticated network modeling
