Floor Pressurization As A Means Of Controlling Smoke During A High-rise Fire

摘要

With advanced strategies and software, total evacuation need not be the last word(s) in life safety strategy. The size and role of elevator shafts, selective pressurization, and the ability to evaluate multiple reactions quickly may combine to form a safer and swifter reaction to the threat of flames and smoke. Three out of four deaths resulting from structural fires are from smoke inhalation. Consequently, being able to predict and control the paths that smoke will travel throughout a building is of vital importance. The goal of maintaining smoke-free areas is particularly important in high-rise buildings due to the world-wide trend in construction of super-tall buildings. With extended escape routes and the added challenges of extinguishing a fire in a tall building, a well-planned smoke management scheme is essential to a successful pre-fire life safety plan.
