Section
3 Requirements for assignment of ECL(2)
3.1 General
3.1.3 Full-scale
mock-up tests are to be carried out, representing all intended combinations
of container sizes and locations and all intended lashing arrangements.
Documentary evidence is to be provided to the Surveyor’s satisfaction
that the tests have been carried out.
3.2 Working areas
3.2.2 The height
of working areas is to be compatible with the proposed stowage of
containers.
3.2.3 Where lashing
is from the hatch cover, a suitable platform should be provided, preferably
at the same level as the top of the hatch cover.
3.2.4 Lashing positions
are to be free of obstructions, such as piping, lashing gear, equipment,
storage bins and hatch cover guides.
3.2.5 Working areas,
excluding lashings in place, are to provide a clear sight of twistlock
handles and allow for the manipulation of lashing gear.
3.3 Fall protection
3.3.1 The opening
below the lowest course of intermediate fencing rails is not to exceed
230 mm and the opening between other courses is not to exceed 380
mm.
3.3.2 Stanchions
are to be fitted about 1,5 m apart.
3.3.3 Gap closing
devices are to return to the closed position when released, except
where this would make them vulnerable to damage during container handling
operations.
3.3.4 Where a rigid
top rail of permanently installed fencing will interfere with movement,
access or cargo-handling operations, lengths of chain may be accepted
as the top rail provided they are fitted between two adjacent fixed
stanchions or a similarly rigid structure spaced at not more than
about 1,0 m apart.
3.3.5 Wire rope
may be accepted as the top rail of folding, hinged or removable fencing,
provided it is used only in limited lengths.
3.3.6 Toeboards
should preferably be 150 mm high. Where this is not possible they
are to be at least 100 mm high.
3.4 Transit areas
3.4.2 The width
of walkways and transit areas is to be at least 600 mm.
3.4.3 Vertical
clearance of walkways and transit areas is to be at least 2,0 m.
3.4.4 Walkways
and transit areas, as far as practicable, are to be free of obstructions,
such as piping, lashing gear, equipment, storage bins and hatch cover
guides.
3.5 Movement between levels
3.5.1 Access openings
are not to be situated in transit areas unless unavoidable.
3.6 Signs and indications
3.7 Access openings
3.7.1 Access openings
are to be provided with adequate handholds.
3.7.2 Access openings
are to be large enough for persons to safely enter and leave.
3.8 Ladders
3.8.1 Ladders with
a potential fall height exceeding 3,0 m are to be provided with safety
cages.
3.8.2 Ladders from
which a person may fall into a hold are to be provided with safety
cages.
3.8.3 Where it
is necessary to ascend or descend by ladder between two or more decks,
the ladders are to be offset at each deck, and protected by fencing
at the top of each ladder.
3.8.4 Where a fixed
ladder gives access to a lashing position through an opening in the
platform, either an adequate handhold is to be provided on the platform,
or the stringers are to be carried above the floor level of the platform
by at least 1,0 m. The ends of the stringers are to be given lateral
support. The top step or rung is to be level with the floor of the
platform.
3.8.5 A fixed ladder
should not slope at an angle greater than 25° from the vertical.
3.8.6 Where the
slope of a ladder exceeds 15° from the vertical, the ladder is
to be provided with suitable handrails not less than 540 mm apart,
measured horizontally.
3.9 Steps
3.9.1 No requirements
for ECL(2).
3.10 Lashing bridges
3.10.2 Manhole
openings at different levels of the lashing bridge should not be located
directly below one another, as far as practicable.
3.10.3 Dimension
‘C1’, see
Table 1.5.1 Container securing dimensions -
ECL(1), ECL(2) and ECL(3), defines the maximum horizontal reach from a lashing bridge
when fitting or removing a lashing rod, thereby reducing the risk
of back injury. Required dimension ‘C1’ may be increased
where necessary, but should not exceed 1300 mm, provided there is
clear indication in the CSM.
3.11 Sightlines and signalling
3.11.1 No requirements
for ECL(2).
3.12 Lashing equipment
3.12.2 The maximum
permissible length of lashing rod is that required, when standing
at the stack foundation, to reach the bottom corner fitting of a 3rd tier container on top of two high-cube containers.
3.12.3 To prevent
hand injury during tightening or un-tightening operations there is
to be a minimum clearance of 70 mm around turnbuckles. This requirement
may be waived provided there is clear indication in the CSM.
3.12.4 Turnbuckles
are to incorporate a locking mechanism which will ensure that the
lashing does not work loose during the voyage.
3.12.5 Lashing
equipment stowage places are to be located in close proximity to the
lashing positions and arranged so that the lashing equipment can be
easily retrieved from the stowage location.
3.12.6 Bins are
to be designed for ease of use and handling.
3.13 Electrical requirements
3.13.1 The level
of lighting is to be even between one area and another.
3.13.2 Lighting
is to be arranged to minimise glare to deck workers.
3.13.3 Minimum
light levels are as follows:
-
Access routes –
10 lux.
-
Lashing positions
– 50 lux.
