Thus, if forced ventilation is to be used, and built-in systems are not available, PPV and NPV are the obvious tactics the fire service would employ. Of these, PPV is considered the more effective as it provides a known route in for fresh air, and overpressure inside the building will lead to quicker movement of air smoke and gases to the outside, than can be achieved by negative pressurisation. In some circumstances, such as where it is critical that the designated exit vent is the only one to be employed, NPV can be used effectively.

pressurized stairwell Explanation: Fire prevention. Thanks to a filter and an engine the air in the stairwell is kept "pressurized". In case of fire it makes sure that the flames do not spread. -------------------------------------------------- Note added at 2 ore (2008-05-31 14:23:12 GMT) -------------------------------------------------- A reference on the internet: "3.3.6 Pressurized Stairwells. A type of smoke-control system in which stair shafts are mechanically pressurized, with respect to the fire area, with outdoor air to keep smoke from contaminating them during a fire incident." from http://www.nfpa.org/assets/files/PDF/ROP/92A-05-ROPDraft.pdf The explanation sounds a bit different than mine, but I clearly remember dealing once with a scheme in which filter and engine were drawn. |
