(1) In addition to the specific provisions for
fire integrity of bulkheads and decks required elsewhere in this part
the minimum fire integrity of bulkheads and decks shall be as prescribed
in table 1 and table 2 of this regulation.
(2) The following requirements shall govern application
of the tables:
-
(a)
tables 1 and 2 shall apply respectively to bulkheads
and decks separating adjacent spaces; and
-
(b) for determining the appropriate fire integrity
standards to be applied to divisions between adjacent spaces, such
spaces are classified according to their fire risk as follows:
-
(i) Control stations (1)
-
Spaces containing emergency sources of power and lighting.
Wheelhouse and chartroom.
Spaces containing the vessel's radio equipment.
Fire-extinguishing rooms, fire-control rooms and fire-recording
stations.
Control room for propulsion machinery when located outside the
machinery space.
Spaces containing centralized fire alarm equipment.
-
(ii) Corridors (2)
-
Corridors and lobbies
-
(iii) Accommodation spaces (3)
-
Spaces as defined in regulation
2(10) and (11) excluding corridors.
-
(iv) Stairways (4)
-
Interior stairways, lifts and escalators other than those
wholly contained within the machinery spaces and enclosures thereto.
In this connection, a stairway which is enclosed only at one level
shall be regarded as part of the space from which it is not separated
by a fire door.
-
(v) Service spaces of low fire risk (5)
-
Lockers and store-rooms having areas of less than 2 m2,
drying rooms and laundries.
-
(vi) Machinery spaces of category A (6)
-
Spaces as defined in regulation
2(14).
-
(vii) Other machinery spaces (7)
-
Spaces as defined in regulation
2(15) including fishmeal processing spaces, but excluding machinery
spaces of category A.
-
(viii) Cargo spaces (8)
-
All spaces used for cargo, including cargo oil tanks, and
trunkways and hatchways to such spaces.
-
(ix) Service spaces of high fire risk (9)
-
Galleys, pantries containing cooking appliances, paint rooms,
lamp rooms, lockers and store-rooms having areas of 2 m2 or
more, and workshops other than those forming part of the machinery
spaces.
-
(x) Open decks (l0)
-
Open deck spaces and enclosed promenades, spaces for processing
fish in the raw state, fish washing spaces and similar spaces containing
no fire risk.
-
The air spaces outside superstructures and deckhouses.
-
The title of each category is intended to be typical rather
than restrictive. The number in parenthesis following each category
refers to the applicable column or row in the tables.
(3) Continuous B class ceilings or linings in
association with the relevant decks or bulkheads may be accepted as
contributing wholly or in part to the required insulation and integrity
of a division.
(4) Windows and skylights to machinery spaces
shall be as follows:
-
(a) where skylights can be opened they shall be
capable of being closed from outside the space. Skylights containing
glass panels shall be fitted with external shutters of steel or other
equivalent material permanently attached;
-
(b) glass or similar materials shall not be fitted
in machinery space boundaries. This does not preclude the use of wire-reinforced
glass for skylights and glass in control rooms within the machinery
spaces; and
-
(c) in skylights referred to in subparagraph (a)
wire-reinforced glass shall be used.
(5) External boundaries which are required by regulation 3(1) to be of steel or equivalent
material may be pierced for the fitting of windows and sidescuttles
provided that there is no requirement elsewhere in this part for such
boundaries to have A class integrity. Similarly, in such boundaries
which are not required to have A class integrity doors may be of materials
to the satisfaction of the Administration.

Note To be applied to both tables 1 and 2, as appropriate.
a No special requirements are imposed upon
these bulkheads in methods IIF and IIIF fire protection.
b In case of method IIIF “B” class bulkheads
of “B-0” rating shall be provided between spaces or groups of spaces of
50 m2 and over in area.
c For clarification as to which applies see
regulations 4 and 5.
d Where spaces are of the same numerical
category and superscript d appears, a bulkhead or deck of the
rating 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 piant
room requires an “A-0” bulkhead.
e Bulkheads separating the wheelhouse,
chartroom and radio rom from each other may be “B-0” rating.
f Fire insulation need not be fitted if the
machinery space in category (7), in the opinion of the Administration,
has little or no fire risk.
* Where an asterisk appears in the tables
the division is required to be of steel or equivalent material but is not
required to be of “A” class standard.
