The following is the formula for calculating the time of emergency evacuation from the platform level given under Subclause of CFDOM: ])1([ 21 21 BANA T  (1) where Q1 is the number of passengers on train。 Q2 the waiting passengers and station staffs on platform。 A1 the throughput capacity of automatic escalator,person/(min m)。 A2 the throughput capacity of passenger staircase,person/(min m)。 N the number of automatic escalators。 B is the total width of passenger staircases(m).In Eq.(1),1 is the response time of the personnel,which is fixed by CFDOM according to the response time of alarming system,broadcasting system design inside the subway. on entries/exits Subclause of CFDOM stipulates:The number of entries and exits of a metro station shall be provided in accordance with the passenger flow to be admitted and ,at least two shall be width of each entry/exit shall be calculated with the designed farfuture directionspecific passenger flow multiplied by a uniformity factor of ～ . on staircase and escalator Subclause of CFDOM stipulates:Other than meeting the passenger admitting and discharging requirements,the total number of passenger staircases and automatic escalators provided shall also be verified against the requirement on the time of emergency evacuation from the platform level which should be no more than 6 firefighting staircases and vertical lifts should not be taken into account when planning for the emergency evacuation. on throughput capacity and width of evacuating passage In China metro construction,maximum passenger throughput capacity of all parts and minimum width of all architectural locations of the metro station should be designed according to subclause of CFDOM. occupant evacuation requirements of fire engineering In fire engineering,requirement on occupant evacuation is that all occupants must be evacuated to safe venue(or places)before a fire is developed into hazard to human can be described in . Mathematic description is as follows: ASETRSET (2) where ASET is the available safety Egress time。 RSET the required safety Egress time. of ASET According to the research results currently available(Shi,Li,Huo et al.,2020。 Shi,Lu,Chow et al.,2020),in fire safety engineering analysis,occupant safe evacuation process during a fire is generally divided into severa stage。
