DSC 9/15, paragraph 4.3 and MSC.193(79) "BC Code 2004 Edition"
(MSC 79/23/Add.4, annex 40)
Background
1
At the ninth session of the DSC Sub-Committee, Japan submitted a document
(DSC 9/4/2) containing various issues for consideration to facilitate the finalization of the draft
revised Code of Safe Practice for Solid Bulk Cargoes (BC Code). The Sub-Committee
considered only part of the document (paragraph 2.1 and section 4 of the annex of DSC 9/4/2)
due to time limitation, and requested the working group to finalize the draft revised BC Code
incorporating that part of the proposal of Japan with the view to adoption at the seventy-ninth
session of the Maritime Safety Committee. Regarding the other part of the proposal, the
Sub-Committee invited Japan to submit a definitive version of its document for consideration at
DSC 10 (DSC 9/15 paragraph 4.3).
2
At its seventy-ninth session, the Committee adopted the revised BC Code
(2004 BC Code) by resolution MSC.193(79).
Investigation of the 2004 BC Code
3
Responding to the Sub-Committee’s request, The National Maritime Research Institute of
Japan (NMRI) investigated the revised BC Code for the purpose of improvement. The results
of the investigation are set out in the annex to this document.
For reasons of economy, this document is printed in a limited number. Delegates are
kindly asked to bring their copies to meetings and not to request additional copies.

In the investigation, the NMRI mainly examined appendix 1 of the BC Code, i.e., the
individual entries for solid bulk cargoes. Then, the NMRI pointed out the lack of uniformity in
the expression of the requirements and inconsistencies, which may not be related to safety and
could be considered as editorial errors.
5
The purpose of this document is solely to provide information for improvement of the
BC Code and have nothing to do with the mandatory application of the Code.
Action requested of the Sub-Committee

The Sub-Committee is invited to consider the results of the investigation set out in the
annex to this document and take action as appropriate.

ANNEX
RESULTS OF THE INVESTIGATION ON THE CODE OF SAFE PRACTICE FOR
SOLID BULK CARGOES, 2004∗
The revised BC Code, which was adopted at the seventy-ninth session of the Maritime Safety
Committee by resolution MSC.193(79), was investigated for the purpose of improvement,
especially, on the appendix 1 of the Code, i.e., the individual entries for solid bulk cargoes.
1
Unnecessary varieties in expression of requirements in appendix 1
Use of standardized expression in the entries for cargoes was agreed by the Sub-Committee,
based on the submission by the Netherlands DSC 7/4/2, to make the BC Code more user-friendly.
Furthermore, use of such standardized expression facilitates the translation and implementation
of the BC Code. In view of this, we investigated the expressions in appendix 1 of the Code to
make the BC Code more user-friendly. In paragraphs for "STOWAGE & SEGREGATION",
"HOLD CLEANLINESS", "WEATHER PRECAUTIONS", "LOADING", "PRECAUTIONS",
"VENTILATION", "CARRIAGE", "DISCHARGE" and "CLEAN UP", various unnecessary
varieties of expressions were observed, respectively.
1.1
STOWAGE & SEGREGATION
(1)
Segregation from foodstuffs and class 8 liquids
One of the following expressions should be chosen:
"Separated from" foodstuffs and all class 8 liquids.
This text appears in the entries for the following cargoes:
ALUMINIUM FERROSILICON POWDER UN 1395
ALUMINIUM SILICON POWDER, UNCOATED UN 1398
FERROSILICON UN 1408
FERROSILICON (MHB)
SILICOMANGANESE (low carbon) ZINC ASHES UN 1435
"Separated from" foodstuffs.
"Separated from" all class 8 liquids.
ALUMINIUM SMELTING BY-PRODUCTS OR ALUMINIUM REMELTING
BY-PRODUCT UN 3170
"Separated from" foodstuffs and all class 8 materials (goods in packaged form and solid
bulk materials).
FLUORSPAR
(2)
Segregation from foodstuffs
The standardized expression, "separated from" foodstuffs, is used for many cargoes. On the
other hand, the expression "to avoid contamination, this cargo should be "segregated from" all
foodstuffs" is used for FLY ASH. The vague expression "segregated from" should be
substituted by the standardized expression to eliminate ambiguity.

Inconsistencies
2.1
AMMONIUM SULPHATE
Though this cargo is group C, there is the following text in "HAZARD":
Dust may cause skin and eye irritation. Harmful if swallowed. Danger of heavy
corrosion of framing, side plating etc. if sweating of cargo space occurs.
In the schedule for "AMMONIUM NITRATE BASED FERTILIZERS (non-hazardous)", there is
the following text in "HAZARD":
Even though this cargo is classified as non-hazardous, it will behave in the same way as
the ammonium nitrate fertilizers in class 9 when heated strongly, by decomposing and
giving off toxic gases.
I:\DSC\10\4.doc
DSC 10/4
ANNEX
Page 14
Taking the above text into account, for user-friendliness, the following text can be incorporated
as the text for "HAZARD" in the schedule for "AMMONIUM SULPHATE", instead of the text
"danger of heavy corrosion of framing, side plating etc. if sweating of cargo space occurs":
Even though this cargo is classified as non-hazardous, it may cause heavy corrosion of
framing, side plating etc. if sweating of cargo space occurs.
2.2
POTASSIUM CHLORIDE
Though this cargo is group C, there is the following text in "HAZARD":
Potassium Chloride is corrosive when wet.
Taking into account the text in the schedule for "AMMONIUM NITRATE FERTILIZERS
(non-hazardous)" (see the above paragraph for "AMMONIUM SULPHATE"), the text can be
substituted by the following:
Even though this cargo is classified as non-hazardous, it may cause heavy corrosion when
wet.
2.3
POTASH
This cargo is hygroscopic and "surface ventilation" is required for this cargo, while "do not
ventilate" is required for hygroscopic cargoes, in general.
2.4
PEANUTS (in shell) and TAPIOCA
Based on the description in the entries for these cargoes, these cargoes may heat spontaneously,
though these cargoes are in Group C. On the other hand, surface ventilation is required for
these cargoes while ventilation should generally be limited for cargoes which may heat
spontaneously. The requirements for these cargoes should be reviewed.
2.5
Procedures for gas monitoring of coal cargoes
In the appendices of entries for "BROWN COAL BRIQUETTES" and for "COAL", procedures
for gas monitoring of BROWN COAL BRIQUETTE/COAL cargoes are included. In
paragraphs 2.2.1 of these procedures, siting of sampling points are required as follows:
Two sample points should be provided per hold, one on the port side and one on the
starboard side of the hatch cover.
On the other hand, in paragraphs 2.2.2 of these procedures, the requirements on the sampling
points are the following:
Each sample point should comprise a hole of diameter approximately 12 mm positioned
as near to the top of the hatch coaming as possible.
Sampling points are sited on the side of hatch cover or on the hatch coaming depending on the
structure of hatch covers. Therefore, the relevant wording in the both texts above should be
read as "hatch cover or hatch coaming".

Among these cargoes, the following are the dangerous goods other than class 7:
AMMONIUM NITRATE UN 1942 (Class 5.1)
AMMONIUM NITRATE BASED FERTILIZER UN 2067 (Class 5.1)
AMMONIUM NITRATE BASED FERTILIZER UN 2071 (Class 9)

SODIUM NITRATE UN 1498 (Class 5.1)
SODIUM NITRATE AND POTASSIUM NITRATE MIXTURE UN 1499
(Class 5.1)
On the other hand, natural ventilation is required for solid bulk dangerous goods other than
class 7 by regulation II-2/19.3.4.3 in SOLAS Convention as follows:
3.4.3
Natural ventilation shall be provided in enclosed cargo spaces intended for the
carriage of solid dangerous goods in bulk, where there is no provision for
mechanical ventilation. (See also table 19.2 in chapter II-2.)
If the requirement in SOLAS Convention was just for structure and equipment, there could be no
inconsistency between the above mentioned ventilation requirements in the BC Code and in
SOLAS Convention. However, if the requirement in SOLAS Convention was interpreted as the
operational requirement for natural ventilation, there could be inconsistency between these
requirements. Clear interpretation of the requirement in SOLAS Convention may be necessary.

The texts in the columns for "VENTILATION" in entries for "WOODCHIPS" and "WOOD
PULP PELLETS" are "see precautions". However, there are no concrete requirements for
ventilation in the columns for "PRECAUTIONS" in these entries. This issue should be
considered and appropriate amendment to the BC Code should be made.
2.7
Description on fire risk of COAL
In the column on HAZARDS of COAL, the following is described:
This cargo has a low fire-risk.
On the other hand, in the column on HAZARDS of BROWN COAL BRIQUETTES, the
description is as follows:
Briquettes are easily ignited, liable to spontaneous combustion and will deplete oxygen in
cargo space.
We suppose that the description for COAL was made to keep the consistency with table 1 in
MSC/Circ.671 which said COAL was "low fire risk cargo". On the other hand, in table 1 in
MSC/Circ.1146, i.e., revised MSC/Circ.671, COAL and BROWN COAL BRIQUETTES are
listed as the cargoes for which a fixed gas fire-extinguishing system may be exempted by the
reason that these are listed in regulation II-2/10 in SOLAS Convention. In MSC/Circ.1146, it is
not said that COAL is "low fire risk cargo".
Thus, the description for COAL should be reviewed to keep the consistency with the description
for BROWN COAL BRIQUETTES.
2.8
AMMONIUM NITRATE BASED FERTILIZER (non-hazardous)
In the entry for AMMONIUM NITRATE BASED FERTILIZER (non-hazardous) under
HAZARDS, the following sentences appear:
This cargo is non-combustible or with a low fire-risk.
Even though this cargo is classified as non-hazardous, it will behave in the same way as
the ammonium nitrate based fertilizers classified in class 9 under UN 2071 when heated
strongly, by decomposing and giving off toxic gases.
Though this cargo is in Group C, the entry for this cargo has EMERGENCY PROCEDURES
similar to the entries for AMMONIUM NITRATE BASED FERTILIZER UN 2067 & UN 2071.
The group of this cargo should be re-evaluated. If this cargo is categorized as group B,
amendment to MSC/Circ.1146 may be necessary.
2.9
Stowage of ammonium nitrate cargoes
In the column for STOWAGE & SEGREGATION in the entries for AMMONIUM NITRATE
BASED FERTILIZER UN 2067 & UN 2071, it is required that these cargoes should not be
stowed immediately adjacent to any tank or double bottom containing fuel oil heated to more
than 50°C. On the other hand, in the entry for AMMONIUM NITRATE UN 1942, there is no
such requirement. Inclusion of such requirement into the entry for AMMONIUM NITRATE
UN 1942 should be considered for consistency.
I:\DSC\10\4.doc
DSC 10/4
ANNEX
Page 17
For AMMONIUM NITRATE BASED FERTILIZER UN 2067, the following is required:
"If the bulkhead between the cargo space and the engine-room is not insulated to
class A-60 standard, the competent authority should approve an equivalent arrangement."
For AMMONIUM NITRATE BASED FERTILIZER UN 2071, the following is required:
"Fertilizers of this type should be stowed out of direct contact with a metal engine-room
boundary. This may be done, for example, by using flame retardant bags containing
inert materials or by any equivalent barrier approved by the competent authority. This
requirement need not apply to short international voyages."
These requirements, including the application to AMMONIUM NITRATE UN 1942, should be
reviewed for safety and consistency, taking into account that the insulation A-60 is required to
prevent high rate of temperature rise of a surface but the insulation A-60 cannot be effective for
preventing increase of temperature of a surface in the case that the other surface is heated long time.

Requirements which may not be related to safety
As described in DSC 9/4, i.e., the report of the working group on the BC Code at 8th session of
the Sub-Committee, it was agreed that the provisions of the BC Code should be intended only for
safety and not for commercial purposes. In view of this, the provisions which may not be
related to safety should be examined.
3.1
Requirements for non-hazardous cargoes
In appendix 1 of the revised BC Code, there are 87 entries for cargoes categorized into group C,
i.e., the group of cargoes which are neither liable to liquefy (Group A) nor to possess chemical
hazards (Group B). Description in the columns for "HAZARDS" in the entries for 69 cargoes
are "no special hazards" and in the column for "HAZARDS" in the entry for "IRON ORE" only
the effect on magnetic compasses is referred to. On the other hand, the following requirements
are provided in the entries for these cargoes including "IRON ORE". These requirements or the
descriptions in the columns for "HAZARDS" should be reviewed.

Prior to loading, a declaration should be provided by the manufacturer or shipper, stating
that the material has been sufficiently heat-treated and is ready for loading.
MAGNESIA (DEADBURNED)
Overstow pebbles with a layer of sacks.
PEBBLES (sea)
Check vessel stability and stresses. When the cargo is loaded, bulldozers may be used to
trim the cargo reasonably level to the boundaries of the cargo space. To avoid excessive
stress, pig iron, if possible should not be stowed in the 'tween decks' unless in tubs or
bolsters. The amount of the cargo depends on the ship's stability requirements, bolsters
or tubs available and 'tween deck' loading limitations. Any bolsters or tubs stowed on
steel decks require dunnage under them and suitable lashings.
PIG IRON
Salt is water-soluble. In the case of ingress of water into the holds, the risk to the loss of
the stability of the ship through dissolution of salt (formation of a liquid base and shifting
of cargo), should be recognized. The parts of the hatch in contact with the cargo should
be lime washed or coated with paint to prevent corrosion, e.g. tanktops, hoppers, side
plating and bulkheads.
