(1) Stairways and ladders leading to and from
an accommodation spaces and in spaces in which the crew is normally
employed, other than machinery spaces, shall be so arranged as to
provide ready means of escape to the open deck and thence to the survival
craft. In particular in relation to these spaces.
-
(a) at all levels of accommodation at least two
widely separated means of escape shall be provided which may include
the normal means of access from each restricted space or group of
spaces;
-
(b)
-
(i) below the weather deck the means of escape
shall be a stairway and the second escape may be a trunk or a stairway;
and
-
(ii) above the weather deck the means of escape
shall be stairways or doors to an open deck or a combination thereof.
Where it is not practicable to fit stairways or doors, one of these
means of escape may be by means of adequately sized portholes or hatches
protected where necessary against ice accretion;
-
(c) exceptionally the Administration may permit
only one means of escape, due regard being paid to the nature and
location of spaces and to the number of persons who normally might
be accommodated or employed there;
-
(d) a corridor or a part of a corridor from which
there is only one route of escape shall preferably not exceed 2.5
m in length and in no case be greater than 5.0 m in length; and
-
(e) the width and continuity of the means of escape
shall be to the satisfaction of the Administration.
(2) Two means of escape shall be provided from
every machinery space of category A which shall be as widely separated
as possible. Vertical escapes shall be by means of steel ladders.
Where the size of the machinery spaces makes it impracticable, one
of these means of escape may be omitted. In such cases special consideration
shall be given to the remaining exit.
(3) Lifts shall not be considered as forming one
of the required means of escape.
