What is a staircase pressurisation system? The pressurisation of stairwells is engineered to prevent smoke and heat from leaking past closed doors and infiltrating stairwells. The systems control air pressures to restrict smoke and heat movements.A staircase pressurization system is a safety feature commonly used in high-rise buildings and underground structures. Its primary purpose is to maintain a higher air pressure inside a staircase compared to the surrounding areas, such as the building lobby or the outdoors. This pressure difference helps prevent smoke from entering the staircase during a fire, thus providing a safer escape route for building occupants. Where is stair pressurization required? Most building codes require the fire stairwells in a high-rise building to be pressurized to keep smoke out. The stairwell pressurization serves several purposes: • Inhibit migration of smoke to stairwells, areas of refuge, elevator shafts, or similar areas. These systems keep emergency exit routes clear of smoke and fire in the event of an outbreak by controlling the air pressure in an escape route. The air pressure differences between the area on fire and the stairwell ensure a smoke and heat-free emergency escape route.
