Staircase Pressurization System
A staircase pressurization system protects escape routes and fire-fighting shafts against the ingress of smoke. Smoke and fire ventilation is maintained by the pressure within the escape route being higher than that in the adjacent spaces. This provides no protection within the space containing the fire, contain the smoke and heat so that it cannot enter the main building escape routes.
A pressurization system consists of three main components: Supply Air (where air is injected into the area that is to be protected), Pressure Relief (to avoid overpressure when doors are closed) and Air Release (air and smoke is released from the adjoining fire area). Combining these elements creates a positive pressure difference which prevents lobbies and staircases from filling up with smoke.

Smoke Extraction System
Smoke is more dangerous to everyone in fires than heat, flames or structural collapse. The installation of smoke control is defined as an inevitable aid to life safety. The purpose of the smoke control system is to release smoke from the building during the early stages of the fire, permitting low level escape routes to remain clear of smoke and allowing the occupants of the building to evacuate in relative safety.
