SEED CAKE, containing vegetable oil UN 1386

 (b) solvent extractions and expelled seeds, containing not more than 10% of oil and when the amount of moisture is higher than 10%, not more than 20% of oil and moisture combined

The provisions of this schedule do not apply to the following materials, due to those materials not meeting the criteria for class 4.2 materials:

• .1 solvent-extracted rape seed meal, rape seed pellets, soya bean meal, cotton seed meal and sunflower seed meal, containing not more than 4% oil and 15% oil and moisture combined;

• .2 mechanically expelled citrus pulp pellets containing not more than 2.5% oil and 14% oil and moisture combined;

• .3 mechanically expelled corn gluten meal containing not more than 11% oil and 23.6% oil and moisture combined;

• .4 mechanically expelled corn gluten feed pellets containing not more than 5.2% oil and 17.8% oil and moisture combined; and

• .5 mechanically expelled beet pulp pellets containing not more than 2.8% oil and 15.0% oil and moisture combined.

A certificate from a person recognized by the competent authority of the country of shipment shall be provided by the shipper, prior to loading, stating that the oil and moisture content of the material is as specified above.

Note: This entry covers the following:

• .1 all solvent-extracted and expelled seed cakes containing not more than 10% oil, and not more than 10% moisture; and

• .2 all solvent-extracted and expelled seed cakes containing not more than 10% oil and moisture content higher than 10%, in which case the oil and moisture combined must not exceed 20%.

  • The range of oil and moisture content is indicated in the figure.

When, in solvent-extracted seed cake, the oil or oil and moisture content exceeds the percentages stated above, guidance shall be sought from the competent authorities.

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:

The above may be shipped in the form of pulp, meals, cake, pellets and expellers.

Characteristics

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 this 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 this 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.^footnote 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.

Emergency procedures

Remarks

The use of CO₂ is limited to controlling the fire and further amounts may need to be injected from time to time during the sea passage to reduce the oxygen content in the hold. On arrival in port, the cargo will need to be dug out to reach the seat of the fire.
