SAFETY AND FIRE PROTECTION

normally not be at a height of more than one metre.

producing approximately 1,000 litres of foam and provide a typical jetย์นาวี
Dry chemical extinguishers are recognised as the most appropriate type
of extinguisher for the quick knock-down of small hydrocarbon fires.

Carbon dioxide extinguishers have little value at berths or on jetties,
except at points where minor electrical fires could occur. However,
enclosed electrical sub-stations or switch rooms located on marine
terminals should be equipped with an adequate number of carbon dioxide
extinguishers or should have a fixed carbon dioxide system installed.

Foam extinguishers with a capacity in the order of 100 litres of pre-mix
foam solution are suitable for use at berths. They are capable of

length of about 12 metres.

Small foam extinguishers with capacities of about 10 litres are, in most
cases, too limited to be effective in the event of a fire at a terminal.

Where portable foam/water monitors are recommended in Table 19.1,
they may be either portable or wheeled, but should have a discharge

capacity of at least 115 m /hr of foam and water in solution.
At least two portable foam/water monitors should be provided for each
wharf or jetty, together with adequate lengths of foam induction hose and
fire hose to facilitate deployment at their maximum range.

19.5.3 Terminal Fixed Fire-Fighting Equipment

19.5.3.1 Fire Water Supply
Fire water at marine terminals is often provided by the unlimited
supply available from the sea, rivers or dock basin.

Where the fire water supply is obtained from static storage, such
as a tank or reservoir, then the reserve for fire-fighting purposes
should be equivalent to at least 4 hours continuous use at the
maximum design capacity of the fire-fighting system. The reserve
for fire-fighting would normally be additional to that required by
any other user taking water from the same static storage. The
piping arrangements at such storage facilities should be arranged
to prevent use of the fire-fighting reserve for other purposes and
the integrity of the make-up water supply to such a reserve would
need to be assured.

Fire water flow rates and pressures should be sufficient to cover
both extinguishing and cooling water requirements for a fire that
might realistically occur. For typical flow rates, reference should be
made to Table 19.1.
