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

2-Life safety damper


Larry Felker, Life Member, Belimo Americas, Sparks, NV, USA, Sparks, NV

There are four types of life safety dampers recognized in the International Building Code (IBC) and International Fire Code and certified to the UL 555 family of standards. Within these four types,

there are many variations. This presentation defines each type, discusses the requirements for each type in IBC,

Chapter 7 (structural elements of fire and smoke protection) and Chapter 9 (systems for fire and smoke
protection), and clarifies the application for each type of life safety damper
