3.1 Arrangements which may be more suitable for
special types of ships may be accepted, provided that they are equally
safe.
3.2 The length of the accommodation ladder should
be sufficient to ensure that its angle of slope does not exceed 45°.
In ships with large draft ranges, several pilot ladder hanging positions
may be provided, resulting in lesser angles of slope. The accommodation
ladder should be at least 600 mm in width.
3.3 The lower platform of the accommodation ladder
should be in a horizontal position and secured to the ship's side
when in use. The lower platform should be a minimum of 5 m above sea
level.
3.4 Intermediate platforms, if fitted, should
be self-levelling. Treads and steps of the accommodation ladder should
be so designed that an adequate and safe foothold is given at the
operative angles.
3.5 The ladder and platform should be equipped
on both sides with stanchions and rigid handrails, but if handropes
are used they should be tight and properly secured. The vertical space
between the handrail or handrope and the stringers of the ladder should
be securely fenced.
3.6 The pilot ladder should be rigged immediately
adjacent to the lower platform of the accommodation ladder and the
upper end should extend at least 2 m above the lower platform. The
horizontal distance between the pilot ladder and the lower platform
should be between 0.1 and 0.2 m.
3.7 If a trapdoor is fitted in the lower platform
to allow access from and to the pilot ladder, the aperture should
not be less than 750 mm x 750 mm. The trapdoor should open upwards
and be secured either flat on the embarkation platform or against
the rails at the aft end or outboard side of the platform and should
not form part of the handholds. In this case the after part of the
lower platform should also be fenced as specified in paragraph 3.5
above, and the pilot ladder should extend above the lower platform
to the height of the handrail and remain in alignment with and against
the ship's side.
3.8 Accommodation ladders, together with any suspension
arrangements or attachments fitted and intended for use in accordance
with this recommendation, should be to the satisfaction of the Administrationfootnote.
