- Abstract
- [ABSTRACT IN ENGLIGH] Casualties in the course of fires are almost exclusively caused by fire smoke and are often regreted by small and medium fire with little damage in the living- and sleeping area (flats, homes, hotels). The problem 'fire smoke' is a main cause for the consequences of fire and the influence of fire smoke on injuries is extremely high and still increasing. This especially applied to the increasing number of large, roofed-in buidings, i.g., shopping-centers, offices, lounges of airports and so forth, in which very many people spend their time. In large roofed-in areas, housing many people, cautions have to be made to exclude actual or supposed dangers by fires as extensively as possible. The ventilation of the developing smoke has a special improtance besides other cautions. In the ignition phase of a fire as well as in cases of limited fire spread caused by sprinkler or very high smoke-free zones problems arise to ventilate off the mixture of developed smoke and air by the normal buoyance. For these cases a 'combined ventilation system' is presented consisting of emission ventilators and the normal RWA system working because of buoyance. The construction of this system is described and the construction data calculated.
