Regulation 13.3.3.2
The term “lowest open deck” shall be understood as the lowest fire category 10 area (regulation 9.2.3.3.2). This
applies regardless of position of accommodation and position of this open deck (forward / aft). Areas of open
deck of insignificant area (mooring stations, etc.) can be disregarded.
Regulation 13.3.3.3 and.4
For spaces above the lowest open deck, DNV may on a case by case basis accept trunk or ladders to deck above
as means of escape from corridors that otherwise would be considered dead end corridors. This is, however,
only accepted if two other means of escape according to Regulation 13.3.3.3 is arranged from one end of such
corridor. A window is however not accepted in this regard.
Regulation 13.3.3.4
A dead end corridor is defined as a corridor or part of a corridor from which there is only one escape route.
