9.4.2.1.3 Cargoes liable to give off vapours or gases which can form an explosive mixture with air should be stowed in a mechanically ventilated space.
9.4.2.1.4 Prohibition of smoking in dangerous areas should be enforced, and clearly legible "NO SMOKING" signs should be displayed.
9.4.2.2 Materials of class 5.1
9.4.2.2.1 Cargoes of this class should be kept as cool and dry as reasonably practicable and should be stowed clear of all sources of heat or ignition. They should also be stowed "separated from" other combustible materials.
9.4.2.2.2 Before loading cargoes of this class, particular attention should be paid to the cleaning of the cargo spaces into which they will be loaded. As far as reasonably practicable, non-combustible securing and protecting materials and only a minimum of dry wooden duunage should be used.
9.4.2.2.3 Precautions should be taken to avoid the penetration of oxidizing materials into other cargo spaces, bilges, etc.
9.4.2.3 Materials of class 7
9.4.2.3.1 Cargo spaces used for the transport of Low Specific Activity materials (LSA-I) and Surface Contaminated Objects (SC0-I) should not be used for other cargoes until decontaminated by a qualified person such that the non-fixed contamination on any surface when averaged over an area of 300 cm イ does not exceed the following levels:
4 Bq/cm2 for beta and gamma emitters and the low-toxicity alpha emitters; natural uranium; natural thorium; uranium-235 or uranium-238; thorium-232; thorium-228 and thorium-230 when contained in ores, physical or chemical concentrates; radionuclides with a half-life of less than 10 days; and
0.4 Bq/cm2 for all other alpha emitters.
9.4.2.4 Materials of class 8 or materials having similar properties
9.4.2.4.1 These cargoes should be kept as dry as reasonably practicable.
9.4.2.4.2 Before loading these cargoes, attention should be paid to the cleaning of the cargo spaces into which they will be loaded and in particular whether these spaces are dry.
9.4.2.4.3 Penetration of these materials into other cargo spaces, bilges, wells and between the ceiling boards should be prevented.
9.4.2.4.4 Particular attention should be paid to the cleaning of the cargo spaces after unloading, as residues of these cargoes may be highly corrosive to the ship's structure. Hosing down of the cargo spaces followed by careful drying is preferred.
9.4.3 Segregation between bulk materials possessing chemical hazards and dangerous goods in packaged form
Unless otherwise required in this section or in the individual entries in [Group]B, segregation between bulk materials and dangerous goods in packaged form should be in accordance with the following table.
For packaged dangerous goods the individual schedules of the IMDG Code should be consulted for additional requirements with regard to stowage and segregation."
・ By the same reason, the word "material(s)" in the tables and the notes should be retained as the existing description.
(30-12) Section 10
The expressions in the existing Code should be retained.
(30-13) Section 12
See comment (39).
(31) Re: Foreword - Editorial
Regarding the sentences proposed by Norway. I would like to propose the following changes including deletion of the last sentence, by the reason that the latest amendment to Chapter VI of the Convention is just the amendments to the wordings in the requirement on Cargo Securing Manuals which is not related to the carriage of solid bulk cargoes:
(32) Re: Foreword - Information
Regarding the sentences proposed by Norway, It should be noted that the regulation numbers in Chapter II-2 will be changed as follows at 1 July, 2002:
"Detailed fire protection arrangements for ships carrying solid bulk cargoes are incorporated in Chapter II-2 of the Convention by regulations [53 and 54] [10 and 19]. Attention is drawn to regulation [54.3] [19.3] which provides for a Document of Compliance to be issued to ships carrying dangerous goods including those carried in bulk."
Note: New regulation 19 is almost the same as the existing regulation 54. New regulation 10.6.2 is the requirement for the cargo spaces carrying dangerous goods.
(33) Re: Section 3.5.2.2
I am of the opinion that paragraph 3.5.2.2 should not be deleted.
".2 if maintaining ventilation endangers the ship or the cargo, it may be interrupted unless there is a risk of explosion or other danger due to interruption of the ventilation;"
