8.1 Case 1: Congestion takes place on deck 5 (door
1 and stair A), deck 6 (door 1, stairs A and B), deck 7 (corridor

the total time is below the limit (see paragraph 9.1 of this example)
and no design modifications are needed.
8.2 Case 2: Congestion takes place on deck 6 (stairs
A, B and C) and deck 7 (stairs A, B and C). However, since the total
time is below the limit (see paragraph 9.2 of this example) no design
modifications are needed.
