5. Checking ventilation performance by scenario

Once the ventilation system has been sized and designed, it is necessary to check that satisfactory performance has been achieved for realistic fire scenarios. This ensures that conditions compatible with user evacuation and emergency response are achieved. If this is not the case, the results of the scenario study will provide information on the revisions to be made to the design.

5.1 Notion of scenario, their choice

A fire scenario is a set of parameters describing the emergency situation we wish to examine. The main parameters are :

  1. the precise location of the fire:

    • positioning on the network (possibly time-dependent if the incident occurs on a moving train),

    • ...
