Schedule source MSC.539(107), Annex 9, Appendix 1, IMSBC Code Amendment 07-23 · pages 399, 400, 401, 402
Description
Residue remaining after oil has been extracted by a solvent process or expelled mechanically from oil-bearing seeds. The cereals and cereal products included in this schedule are those derived from: Bakery materials Mill feed pellets Barley malt pellets Niger seed, expellers Beet Oil cake Bran pellets Palm kernel Brewer’s grain pellets Peanuts Citrus pulp pellets Pellets, cereal Coconut Pollard pellets Copra Rape seed Corn gluten Rice bran Cotton seed Rice broken Expellers Safflower seed Gluten pellets Seed expellers, oily Ground nuts, meal Soya bean Hominy chop Strussa pellets Linseed Sunflower seed Maize Toasted meals Meal, oily The above may be shipped in the form of pulp, meals, cake, pellets and expellers.
Hazard
May self-heat slowly and, if wet or containing an excessive proportion of unoxidized oil, ignite spontaneously. Liable to oxidize, causing subsequent reduction of oxygen in the cargo space. Carbon dioxide may also be produced.
Stowage and Segregation
See 9.3 of IMSBC Code. If the bulkhead between the cargo space and the engine-room is not insulated to class “A-60” standard, solvent extraction seed shall be stowed “away from” the bulkhead.
Hold Cleanliness
Clean and dry as relevant to the hazards of the cargo.
Weather Precautions
This cargo shall be kept as dry as practicable. This cargo shall not be handled during precipitation. During handling of this cargo, all non-working hatches of the cargo spaces into which this cargo is loaded, or to be loaded, shall be closed.
Loading
This cargo shall only be accepted for loading when the cargo is substantially free from flammable solvent and a certificate from a person recognized by the competent authority of the country of shipment specifying the oil content and moisture content is issued. Trim in accordance with the relevant provisions required under sections 4 and 5 of IMSBC Code.
Precautions
Before shipment, this cargo shall be properly aged; the duration of ageing required varies with the oil content. The temperature of this cargo shall be measured regularly at a number of depths in the cargo spaces and recorded during the voyage. If the temperature of the cargo reaches 55°C and continues to increase, ventilation to the cargo shall be stopped. If self-heating continues, then carbon dioxide or inert gas shall be introduced to the cargo space. Notwithstanding the previous requirement, in the case of solvent-extracted seed cakes the use of carbon dioxide or inert gas shall be withheld until fire is apparent. Entry of personnel into cargo spaces for this cargo shall not be permitted until tests have been carried out and it has been established that the oxygen content has been restored to a normal level.* When the planned interval between the commencement of loading and the completion of discharge of this cargo exceeds 5 days, the cargo shall not be accepted for loading unless the cargo is to be carried in a cargo space equipped with facilities for introducing carbon dioxide or inert gas into the space. Smoking and the use of naked lights shall be prohibited in the vicinity of the cargo space during loading and unloading and on entry into the cargo spaces at any other time. Electrical circuits for equipment in cargo spaces which is unsuitable for use in an explosive atmosphere shall be isolated by removal of links in the system other than fuses. Spark-arresting screens shall be fitted to ventilators to the cargo spaces containing this cargo.
Ventilation
Surface ventilation, either natural or mechanical, shall be conducted, as necessary, for removing any residual solvent vapour. To prevent self-heating of the cargo, caution is required when using mechanical ventilation.
Carriage
Hatches of the cargo spaces carrying this cargo shall be weathertight to prevent the ingress of water.
Discharge
No special requirements.
Clean-up
No special requirements. * Refer to Revised recommendations for entering enclosed spaces aboard ships (resolution A.1050(27)).
