A fire evacuation guidance system includes a pair of dissimilarly colored laser beams generated by at least one laser emitting device. The dissimilarly colored laser beams are generated substantially parallel to hallways of a (5) structure and subsequently reflected, where required, to direct occupants to a shortest exit route in the event of a fire emergency. That is, a first laser beam of one color is generated substantially parallel to one side of a hallway while a second laser beam of a second color different from the first color is generated substantially parallel to the opposite side of the hallway. So long as an occupant (10) of the structure positions himself or herself between the two laser beams and keeps the laser beam of the first color on his or her right hand side, the occupant will be directed to the closest exit in the event of a fire emergency.

L'invention concerne un système de guidage d'évacuation incendie. Ce système comprend deux faisceaux laser de couleurs différentes générés par au moins un dispositif d'émission laser. Les faisceaux laser de couleurs différentes sont générés sensiblement parallèles aux couloirs d'une structure et sont subséquemment réfléchis, le cas échéant, pour orienter les occupants vers la sortie de secours la plus proche, en cas d'incendie. Un premier faisceau laser d'une couleur est généré sensiblement parallèle à un côté d'un couloir, tandis qu'un second faisceau laser d'une seconde couleur différente de la première couleur est généré sensiblement parallèle au côté opposé du couloir. Lorsqu'un occupant de la structure se positionne entre les deux faisceaux laser et garde le faisceau laser de la première couleur à son côté droit, l'occupant est dirigé vers la sortie de secours la plus proche en cas d'incendie.
