Pressurised Fire Escape Staircase Systems
Some multi-storey buildings are fitted with pressurising systems which protect Fire Escape Corridors, Lobbies, Lifts, Escape Routes and Fire-Fighting Staircases against the ingress of Smoke in the event of a fire.
When the building Fire Alarm is activated, large fans operate which gently pressurize the Escape Routes and Fire-Fighting Staircases with fresh air, which keeps deadly smoke out and allows people to breathe as they vacate the building. The resulting air pressures, door forces and air velocities produced must be tightly controlled.
We are experts in the maintenance and repair of these systems, using specialist equipment to measure air pressure, door forces and velocities produced against the current regulatory standards.
