9.3.1.1 The potential hazards of the cargoes in
Group B and falling within the classification of 9.2.2 and 9.2.3 entail
the need for segregation of incompatible cargoes. Segregation shall
also take account of any identified subsidiary risk.
9.3.1.2 In addition to general segregation as
between whole classes of materials there may be a need to segregate
a particular material from others. In the case of segregation from
combustible materials this shall be understood not to include packaging
material, ceiling or dunnage; the latter shall in these circumstances
be kept to a minimum.
9.3.1.3 For the purpose of segregating incompatible
materials, the words “hold” and “compartment”
are deemed to mean a cargo space enclosed by steel bulkheads or shell
plating and by steel decks. The boundaries of such a space shall be
resistant to fire and liquid.
9.3.1.4 When two or more different solid bulk
cargoes of Group B are to be carried, the segregation between them
shall be in accordance with 9.3.4.
9.3.1.5 Where different grades of a solid bulk
cargo are carried in the same cargo space, the most stringent segregation
provisions applicable to any of the different grades shall apply to
all of them.
9.3.1.6 When solid bulk cargoes of Group B and
dangerous goods in packaged form are to be carried, the segregation
between them shall be in accordance with 9.3.3.
9.3.1.7 Incompatible materials shall not be handled
simultaneously. Upon completion of loading one cargo, the hatch covers
of every cargo space shall be closed and the decks cleaned of residue
before the loading of other material is commenced. When discharging,
the same procedures shall be followed.
9.3.1.8 To avoid contamination, all foodstuffs
shall be stowed:
-
.1 “separated from” a material which
is indicated as toxic;
-
.2 “separated by a complete compartment
or hold from” all infectious materials;
-
.3 “separated from” radioactive materials;
and
-
.4 “away from” corrosive materials.
-
The terms are defined in 9.3.3 and 9.3.4, as appropriate.
9.3.1.9 Materials which may evolve toxic gases
in sufficient quantities to affect health shall not be stowed in those
spaces from where such gases may penetrate into living quarters or
ventilation systems connecting to living quarters.
9.3.1.10 Materials which present corrosive hazards
of such intensity as to affect either human tissue or the ship's structure
shall only be loaded after adequate precautions and protective measures
have been taken.
9.3.1.11 After discharge of toxic or oxidizing
cargoes, the spaces used for their carriage shall be inspected for
contamination before being used for other cargoes. A space which has
been contaminated shall be properly cleaned and examined before being
used for other cargoes.
9.3.1.12 After discharge of cargoes, a close inspection
shall be made for any residue, which shall be removed before the ship
is presented for other cargoes.
9.3.1.13 For cargoes for which in case of an emergency
the hatches shall be opened, these hatches shall be kept free to be
capable of being opened up.
