Staircase Pressurization with Smoke Ventilation
Staircase Pressurization with Smoke Ventilation – Know What It Is & What We Offer
Staircase pressurization is a life safety system designed to keep stairwells in buildings free of smoke during a fire. This works by maintaining a higher air pressure in the stairwell compared to adjacent areas, preventing smoke from entering. This ensures a clear and safe evacuation route for occupants. It also provides a smoke-free environment for firefighters to access the building.
Why is Staircase Pressurization Required?
Safe Evacuation: During a fire, staircases serve as the primary means of egress. Keeping them free of smoke is critical for the safe evacuation of occupants.
Firefighter Access: Clear stairwells allow firefighters to quickly and safely move through the building. This improves their ability to combat the fire. It also helps them rescue occupants.
Compliance with Building Codes: Many building codes need staircase pressurization systems. These systems guarantee the safety of building occupants and emergency responses. Fire safety standards also mandate them.
Prevention of Smoke Infiltration: Smoke inhalation is a leading cause of death in fires. By preventing smoke from infiltrating stairwells, the risk to occupants is significantly reduced.
According to NBC PRESSURIZATION is a method adopted for protecting the exits from ingress of smoke, especially in high-rise buildings.
Staircase pressurization is mandatory for any residential building over 15 meters in height. It is also required for other types of buildings like hospitals, shopping malls, and educational institutions.
Types of Pressurization Systems We Offer :
Single-Injection System: Air is injected at one point, typically at the base or the top of the stairwell.
Multiple-Injection System: Air is injected at multiple points along the height of the stairwell to keep uniform pressure.
Variable Air Volume System: Adjusts the amount of air injected based on the pressure requirements, providing more precise control.
