Smoke movement in egress routes in a high rise building

Recently, a series of full-scale fire tests were conducted in the NRC ten-storey tower facility during which corridors on the fire floor and the stair shaft were filled with smoke. These tests were part of a project with government and private sector organizations to investigate the use of positive pressure ventilation to vent smoke from high rise buildings. In this paper, the results of the initial stage of fire tests using typical residential furniture (sofas and beds) are discussed including the impact of various parameters on smoke movement in the egress routes. In addition, the experimental data is compared to the results determined using network and multi-compartment zone models.Ces derniers temps, une s\ue9rie d?incendies exp\ue9rimentaux en vraie grandeur ont \ue9t\ue9 r\ue9alis\ue9s dans la tour de 10 \ue9tages du CNRC, au cours desquels on a provoqu\ue9 l?enfumage des couloirs de l?\ue9tage du foyer d?incendie et de la cage d?escalier. Ces essais faisaient partie d?un projet men\ue9 avec des organismes gouvernementaux et le secteur priv\ue9 en vue d?investiguer l?utilisation de la ventilation en surpression pour \ue9vacuer la fum\ue9e des immeubles de grande hauteur. On traite dans ce document des r\ue9sultats obtenus aux stades initiaux des essais sur des \ue9l\ue9ments de mobilier r\ue9sidentiel types (sofas et lits), notamment de l?incidence de divers param\ue8tres sur le mouvement de la fum\ue9e le long des parcours d?\ue9vacuation. De plus, on compare les donn\ue9es exp\ue9rimentales aux r\ue9sultats \ue9tablis au moyen de mod\ue8les en r\ue9seau de zones \ue0 compartiments multiples.Peer reviewed: YesNRC publication: Ye
