1 General
1.1 This appendix lists materials which were known at the time of publication to be carried in bulk and identifications of the materials. It should be carefully noted that this list of materials is not exhaustive and that the physical properties attributed to them are for guidance only.
1.2 The meanings of the identifications are as follows:
Group "A" includes materials which may liquefy if shipped at a moisture content in excess of their transportable moisture limit.
Group "B" includes materials which may possess a chemical hazard which could give rise to a dangerous situation on board ship.
Group "C" includes materials which are neither liable to liquefy nor to possess chemical hazards.
When the material is categorized into "A or C " in the Group (cf. "IRON PYTITES"), there are both cases that the material may liquefy and that the material is not liable to liquefy.
When the material is categorized into "B or C " in the Group, there are both cases that the material may possess a chemical hazard and that the material is not liable to possess chemical hazards.
When the material is categorized into "A and B" in the Group (cf. "METAL SULPHIDE CONCENTRATES") the material may liquefy and may possess a chemical hazard.
When the material is categorized into "(A and B) or B" in the Group (cf. "COAL" ), there are both cases that the material may liquefy and may possess a chemical hazard and that the material may possess a chemical hazard and is not liable to liquefy.
1.3 The following materials are non-cohesive when dry:
AMMONIUM NITRATE
AMMONIUM NITRATE FERTILIZERS
AMMONIUM SULPHATE
BORAX ANHYDROUS
CALCIUM NITRATE FERTILIZER
CASTOR BEANS
DIAMMONIUM PHOSPHATE
MONOAMMONIUM PHOSPHATE
MURIATE OF POTASH (POTASSIUM CHLORIDE) (KCI)
POTASH
POTASSIUM NITRATE
POTASSIUM SULPHATE
SODIUM NITRATE
SODIUM NITRATE AND POTASSIUM NITRATE, MIXTURE
SUPERPHOSPHATE
UREA
Prior to completion of loading, the angle of repose of the materials to be loaded should be determined (see section 6) so as to determine which provisions of this Code relating to trimming apply (see section 5).
1.4 All other materials listed in this appendix are cohesive and use of the angle of repose is, therefore, not appropriate. Materials not listed should be treated as cohesive until otherwise shown.
2 Precautions for the materials which may liquefy
2.1 Varying terminology exists to describe mineral concentrates. All known terms are listed below but the list is not exhaustive.
2.2 Many fine-particles materials, if possessing a sufficiently high moisture content, are liable to flow. Thus any damp or wet cargo containing a proportion of fine particles should be tested for flow characteristics prior to loading.
3 Precautions for the materials which may possess a chemical hazard
3.1 In circumstances where consultation with the competent authority is required prior to bulk shipment of materials, it is equally important to consult authorities at the port of loading and discharge concerning requirements which may be in force.
3.2 Where required, the Medical First Guide for Use in Accidents Involving Dangerous Goods (MFAG) should be consulted prior to loading."
(2) As mentioned above, Group "B and C" in the list should be replaced by "B or C". The group for "IRON PYTITES" should be "A or C". The group for "COAL" should be "(A and B) or B"
