SECTION 2.6 STATION SMOKE CONTROL AND MECHANICAL VENTILATION SYSTEMS ROOT OBJECTIVES The primary intentions of this section are encapsulated in the following statements:- R2.6.1 Maintain tenable conditions for evacuation of occupants. R2.6.2 Provide smoke management in the station for fire-fighting operations. SUB-OBJECTIVES The following criteria define the conditions necessary to fulfil the intentions of this section:- S2.6.1 Provisions for ventilation for life safety purposes such that, in the event of a fire, evacuation routes are maintained:- (i) below thermal threshold for human tenability; and (ii) at visibility levels adequate for occupant evacuation; and (iii) below toxicity threshold for human tenability; and (iv) not impeding the movement and evacuation of occupants. for the period of time required for evacuation. S2.6.2 Provisions for ventilation to maintain safe conditions in the means of escape for evacuees for the period of time required for evacuation. S2.6.3 Provisions for appropriate smoke management system in the station to facilitate fire-fighting operation. S2.6.4 Provisions for adequate ventilation for equipment emitting flammable vapour, to prevent undesirable accumulation of such flammable vapour. Standard for Fire Safety in Rapid Transit Systems 108
