Many believe burns to be the leading cause of death in fire victims. Statistics, however, indicate that smoke inhalation causes between 70% and 80% of fire-related deaths. Burns primarily affect specific parts of a person’s body, whereas smoke inhalation affects all organs.

In the event of an emergency, it takes longer to evacuate multi-storey buildings. Smoke and heat-free emergency escape routes.

Enable fire and rescue services first to evacuate high-risk occupants. A pressurized stairwell provides the remaining evacuees with a smoke and heat-free area where they can wait until evacuated.
Provide fire and rescue services employees with safe areas from which to fight fires.
Provide fire and rescue services employees with escape routes if needed.

Fire smoke is highly toxic, consisting of gases such as carbon monoxide and hydrogen cyanide. The toxicity increases the longer a fire rages. Respiratory distress, loss of consciousness, asphyxiation, and organ failure are some of the effects of smoke inhalation.

What is the stairwell pressurization system?

A stairwell pressurization system is mechanically designed to establish air pressure variations between adjoining areas – such as an emergency escape route and a burning room. These air pressure differences (or variations) ensure that one side of a wall has positive and the other negative air pressure.

In the event of a fire, stairwell doors are opened for entry and exit purposes. The increased air pressure counters the flow of smoke and heat, preventing both from entering the stairwell.
