4 Fire pumps and water service pipes
4.1 General
4.1.2 In floating
docks of less than 200 tonnes lift, at least one fixed hand operated
pump with a permanent sea suction and discharge to the fire main is
to be provided. Floating docks of 200 tonnes lift and over but less
than 1000 tonnes lift, are to be provided with one power pump and
one fixed hand operated pump with a permanent sea suction and discharge
to the fire main.
4.1.3 In floating
docks of 1000 tonnes lift and over, not less than two independently
driven power pumps are to be provided, preferably one pump being placed
in each wing.
4.1.4 In addition, in floating docks of 2000 tonnes lift and over, if a fire in
any one compartment could put all the pumps out of action there is to be an alternative
means of providing water for fire-fighting. This alternative means is to be a fixed
emergency pump independently driven by an engine, or other approved means. This
emergency pump is to be capable of supplying two jets of water to the satisfaction of
the Surveyor. The pump is to be located in a readily accessible position which is not
likely to be rendered inaccessible by a fire in the compartment containing the main fire
pumps. The pump is to be provided with its own sea suction and discharge to the fire
main. A valve is to be provided for isolating the fire main outside the compartment
containing the main fire pumps. This isolating valve is to be situated in a readily
accessible position outside that compartment. However, if shore based fire-fighting
appliances are readily available, consideration may be given to dispensing with the
emergency pump. This will be at the discretion of the Committee.
4.2 Fire hydrants, hoses and nozzles
4.2.1 The number
of fire-hoses to be provided, each complete with couplings and nozzles,
is to be one for each 30 m length of each wing of the dock and one
spare, but in no case less than a total of six (three on each wing)
for floating docks of 1000 tonnes lift and over and not less than
a total of four for smaller docks. These numbers do not include any
hoses required in any engine or boiler room. If necessary, the number
of hoses is to be increased to ensure that hoses in sufficient number
are available and accessible at all times.
4.2.3 All hydrants
in the machinery spaces of floating docks with oil fired boilers,
oil engines or gas turbines are to be fitted with hoses having, in
addition to the nozzles required by Pt 2, Ch 3, 2.8 Nozzles,
nozzles suitable for spraying water on oil, or alternatively, dual
purpose nozzles.
4.3 Portable fire-extinguishers in accommodation and service spaces
4.3.1 Radio
rooms, accommodation and service spaces are to be provided with a
sufficient number of portable fire-extinguishers to ensure that at
least one extinguisher will be readily available for use in every
compartment of the crew spaces to the Surveyor’s satisfaction.
4.3.2 For galleys,
and for spaces containing domestic boilers, one portable fire-extinguisher
suitable for dealing with oil fires or fires in electric cooking equipment
is to be provided.
4.4 Fire-extinguishing appliances in boiler rooms, etc.
4.4.1 In spaces
where oil fired boilers exceeding 3,5 kg/cm2 are situated,
or in spaces containing fuel oil units or settling tanks in floating
docks exceeding 1000 tonnes lift, any one of the following types of
fixed fire-extinguishing installations complying with Pt 2, Ch 3, 3 Fire detection and fire-extinguishing systems and equipment is to be provided:
-
a pressurized water-spraying
system;
-
a fire-smothering
gas installation;
-
a fixed froth installation
supplemented, if necessary, by a fixed or mobile arrangement for pressurized
water or froth spraying to fight fire above floor plates.
Floating docks that are not within the above category will be
specially considered. The fixed installation is to be of type Pt 2, Ch 3, 4.4 Fire-extinguishing appliances in boiler rooms, etc. 4.4.1.(b) in all cases where the flash
point of the fuel oil is less than 60ºC (closed cup test). In
each case, if the engine and boiler rooms are not entirely separate,
or if fuel oil can drain from the boiler room into the engine room
bilges, the combined engine and boiler rooms are to be considered
as one compartment.
4.4.2 There
are to be at least two approved portable extinguishers discharging
froth, or other approved medium suitable for extinguishing oil fires,
in each firing space in each boiler room and each space in which a
part of the fuel oil installation is situated. In addition, there
is to be at least one extinguisher of the same description with a
capacity of 9 litres for each burner, provided that the total capacity
of the additional extinguisher or extinguishers need not exceed 45
litres of any one boiler room.
4.4.3 In each
firing space there is to be a receptacle containing at least 0,28
m3 of sand, sawdust impregnated with soda, or other approved
dry material and a scoop for distributing this material. Alternatively,
an approved portable extinguisher may be substituted therein.
4.5 Fire-fighting appliances in spaces
containing engines or gas turbines
4.5.1 Where engines or gas turbines are used, with a total power not less than
1000 bhp, floating docks of 1000 tonnes lift and over are to be provided with the
following arrangements Pt 2, Ch 3, 4.5 Fire-fighting appliances in spaces containing engines or gas turbines 4.5.1 and Pt 2, Ch 3, 4.5 Fire-fighting appliances in spaces containing engines or gas turbines 4.5.1.(b), and floating docks of under 1000 tonnes lift with
arrangement Pt 2, Ch 3, 4.5 Fire-fighting appliances in spaces containing engines or gas turbines 4.5.1.(b). For docks of under 200 tonnes lift the provision of a
45 litre extinguisher may be waived:
-
There is to be one
of the fixed arrangements required by Pt 2, Ch 3, 4.4 Fire-extinguishing appliances in boiler rooms, etc. 4.4.1.
-
There is to be in
each engine space one approved froth type extinguisher of not less
than 45 litres capacity or equivalent, and also one approved portable
froth extinguisher for each 1000 bhp of the engines or part thereof;
but the total number of portable extinguishers so supplied is not
to be less than two and need not exceed six.
