3.1 Identification of assembly stations

 For both MVZ 1 and MVZ 2, the assembly stations are located at deck 8, which is also the embarkation deck.

3.2 Identification of escape routes

  3.2.1 In MVZ 1, the escape routes are as follows (see figure 3):

  • .1 Deck 5 is connected with deck 6 (and then deck 8 where assembly stations are located) through one stair (stair A) in the fore part of the zone. Four corridors (corridors 1, 2, 3 and 4) and two doors (respectively door 1 and 2) connect the cabins with stair A. The clear widths and lengths are:

  • .2 Deck 6 is connected with deck 7 (and then deck 8) through two stairs (stairs A and B respectively in the fore and aft part of the zone). Four corridors (corridors 1, 2, 3 and 4) and two doors (doors 1 and 2) connect the fore cabins with stair A; and two corridors (corridors 5 and 6) and two doors (doors 3 and 4) connect the aft cabins with stair B. The clear widths and lengths are:
