Notes:
To be applied to both tables 73.1 and 73.2, as appropriate.
-
a For clarification as to which applies see clauses 71 and 74 of this Code.
-
b Where spaces are of the same numerical category and superscript b appears, a bulkhead or deck of the ratings shown in the tables is only required when the adjacent spaces are for a different purpose, e.g. in category (9), a galley next to a galley does not require a bulkhead but a galley next to a paint room requires an A-0 bulkhead.
-
c Bulkheads separating the wheelhouse and chartroom from each other may be 'B-0' rating.
-
d See subclauses (2)(c) and 2(d) of this clause.
-
e For the application of clause 70(2) of this Code, 'B-0' and 'C', where appearing in table 73.1, shall be read as 'A-0'.
-
f Fire insulation need not be fitted if the machinery space of category (7), in the opinion of the Chief Surveyor, has little or no risk.
-
Where an asterisk appears in the tables, the division is required to be of steel or other equivalent material but is not required to be of 'A' class standard. For the application of clause 70(2) of this Code an asterisk, where appearing in table 73.1 except for categories (8) and (10), shall be read as 'A-0'.
74. Protection of Stairways and Lifts in Accommodation and Service Spaces
(1) All stairways shall be of steel frame construction except where the Chief Surveyor sanctions the use of other equivalent material, and shall be within enclosures formed of 'A' class divisions, with positive means of closure at all openings, except that:
(a) a stairway connecting only two decks need not be enclosed, provided the integrity of the deck is maintained by proper bulkheads or doors in one 'tweendeck space. When a stairway is closed in one 'tweendeck space, the stairway enclosure shall be protected in accordance with the tables for decks in clauses 72 or 73 of this Code.
(b) Stairway enclosures shall have direct communication.
