Regulation 9 – Containment of Fire
6 Paragraph 7 is replaced with the following:
(This paragraph applies to ships constructed on or after
1 January 2016)
7.1.1 Ventilation ducts, including single and double wall
ducts, shall be of steel or equivalent material except flexible bellows of short length
not exceeding 600 mm used for connecting fans to the ducting in air-conditioning rooms.
Unless expressly provided otherwise in paragraph 7.1.6, any other material used in the
construction of ducts, including insulation, shall also be non-combustible. However,
short ducts, not generally exceeding 2 m in length and with a free cross-sectional
areafootnote not exceeding 0.02 m2, need not be of steel or equivalent
material, subject to the following conditions:
-
.1 the ducts shall be made of non-combustible
material, which may be faced internally and externally with membranes having low
flame-spread characteristics and, in each case, a calorific valuefootnote not exceeding 45 MJ/m2 of their surface area for the
thickness used;
-
.2 the ducts are only used at the end of the ventilation
device; and
-
.3 the ducts are not situated less than 600 mm,
measured along the duct, from an opening in an "A" or "B" class division,
including continuous "B" class ceiling.
7.1.2 The following arrangements shall be tested
in accordance with the Fire Test Procedures Code:
-
.1 fire dampers, including their relevant means
of operation, however, the testing is not required for dampers located
at the lower end of the duct in exhaust ducts for galley ranges, which
must be of steel and capable of stopping the draught in the duct;
and
-
.2 duct penetrations through "A" class divisions.
However, the test is not required where steel sleeves are directly
joined to ventilation ducts by means of riveted or screwed connections
or by welding.
7.1.3 Fire dampers shall be easily accessible.

paragraphs 7.2.4.1.1 and 7.2.4.1.2; and
-
.2.2 insulated to "A-60" class standard throughout
the spaces they pass through, except for ducts that pass through spaces of
category (9) or (10) as defined in paragraph 2.2.3.2.2.
7.2.5 For the purposes of paragraphs 7.2.4.1.4
and 7.2.4.2.2, ducts shall be insulated over their entire cross-sectional
external surface. Ducts that are outside but adjacent to the specified
space, and share one or more surfaces with it, shall be considered
to pass through the specified space, and shall be insulated over the
surface they share with the space for a distance of 450 mm past the
ductfootnote.
7.2.6 Where it is necessary that a ventilation
duct passes through a main vertical zone division, an automatic fire
damper shall be fitted adjacent to the division. The damper shall
also be capable of being manually closed from each side of the division.

visible indicator which shows the operating position of the damper. Fire dampers
are not required, however, where ducts pass through spaces surrounded by "A" class
divisions, without serving those spaces, provided those ducts have the same fire
integrity as the divisions which they penetrate. A duct of cross-sectional area
exceeding 0.075 m2 shall not be divided into smaller ducts at the
penetration of an "A" class division and then recombined into the original duct
once through the division to avoid installing the damper required by this
provision.
7.3.2 Ventilation ducts with a free cross-sectional
area exceeding 0.02 m2 passing through "B" class bulkheads
shall be lined with steel sheet sleeves of 900 mm in length, divided
preferably into 450 mm on each side of the bulkheads unless the duct
is of steel for this length.
7.3.3 All fire dampers shall be capable of manual
operation. The dampers shall have a direct mechanical means of release
or, alternatively, be closed by electrical, hydraulic, or pneumatic
operation. All dampers shall be manually operable from both sides
of the division. Automatic fire dampers, including those capable of
remote operation, shall have a failsafe mechanism that will close
the damper in a fire even upon loss of electrical power or hydraulic
or pneumatic pressure loss. Remotely operated fire dampers shall be
capable of being reopened manually at the damper.
