The pipes and hydrants shali be so placed that the fire hoses m?y be easily coupled to them The"rr".rg.-.nt of pipes and hydrants shall be such as to avoid the possibility of fr,eezing. Suitable drainagepro'oiiion, shail te provided for fire main piping. Isolation valves shall be installed for all open deck firemain branch., .rr.d for purposes other than-fire fighting.

.1.3 if fitted with periodically unattended machinery spaces in accordancc with regulation Il-1'154'the Administiation shall determine provisions for fixed water fire-extinguishing arrangementsfor such spaces equivalent to those required for normally attended machinery spaces;

.2 in cargo ships:

.2.1 to the satisfaction of the Admrnistration; and

.2.2 with a periodically unattended machinery space orwhen only one person is required on watch,there shall be immediate water delivcry from the fire main system at a suitable pressure, eitherby remote starting of one of the main fire pumps with remote starting from the navigationbndge and fire co-ntrol station, if any, or permanent pressurization of.the fire main system byon.*of the main fire pumps, excepf that the Administration may waive this requirement forcargo ships of less than i,600 gtos totr.r"ge if the fire pump starting arrangement in themachinery space is in an easily accessible position-

The ladder shall be fixed in sucha way that heat is not transGrred into the cnclosure through non-insulated fixing points. Theprotected enclosure shall have minimum intcrnal dimensions of at least fl00 mm x 800 mm,and shall have emergency lighting provisions; or

.2 one sreel ladder leading to a door in the upper part of thc space from which access is providcd to theembarkation deck and additionally, in the lower part of the space and in a position well separatedfrom the ladder referred to, a steel door capable of being operated from each side and whichprovides access to a safe escape route from the lower part of the space to the embarkation deck.

Handrails and othcr handholds shall. ,rf such srrength as to withstand a diitribulcd horizontal load of 750 N/m applied_in the direction of the.:rrre of the clrridor or space, and a distributed vertical load of 750 N/m applied in the downward

'::rction. The two loads need not be applied simultaneously.

t 4 Euacuation analysis*: .i.rpe routes shall be evaluated by an evacuation analysis early in the design proce-ss. The analysis shall be

.-'.1 ro identifir and eliminatc, as far as practicable , congcstion which may develop during an abandonment,:.:. ro norm"i-orr"-.nt of passengeis and crew along escape routes, includingthe possibiliry that crew,.1. leed to move along these rout; in a direction opposite to the movement of passengers. In addition,

.

.. llalysis shall be.rr"Jto dcmonstrate that escape arrangements are sufficiently flexiblc to provide for the:- ,.sibiliry that certain escape roures, assembly stitions, embarkation stations or survival craft may not be

rilable as a result of a casualry.
