Example of use<br />
Overpressure smoke <strong>co</strong>ntrol method; this system <strong>co</strong>nsists of pressurization by<br />
means of the injection of air in spaces which are used as escape routes for people in<br />
case of fire, such as stair wells, passageways, <strong>co</strong>rridors, elevators, etc. Above all in<br />
densely occupied tall buildings. This method is based on smoke <strong>co</strong>ntrol by means of<br />
the speed of air and the artificial barrier which is created by excess air pressure over<br />
smoke, so that it cannot enter escape routes.<br />
